The atomic number Z of plutonium is 94 see inside front cover of the text. The problem is to find the number of neutrons, which is A — Z. The number of protons in the nucleus of an atom is the atomic number Z. The following rules are useful in predicting nuclear stability. We need to arrange the correct conversion factors so that all the units cancel, leaving us with years. We can deduce that number of protons equals number of electrons if the atom is electrically neutral. Atoms and the Periodic Table 42 Atom C:

Chapter 2: These numbers actually have an infinite number of significant figures because they are the result of counting objects. They are the building blocks of all matter. An element is a substance that is made up of a single type of atom.

Atoms and the Periodic Table b. X rays are a form of electromagnetic radiation similar to light but of shorter wavelength. Atoms and the Periodic Table 10 r 18 2. Cathode rays are drawn toward positively charged plates. Protons are positively charged particles in the nucleus.

Neutrons are electrically neutral subatomic particles in the nucleus. Electrons are negatively charged particles that are distributed around the nucleus. Thomson determined the ratio of electric charge to the mass of an individual electron. Millikan calculated the mass of an individual electron and proved that the charge on each electron was exactly the same.

James Chadwick discovered neutrons. Most of them passed through the foil, whereas a small proportion were deflected or reflected. Here 18 is the atomic number of Argon. Atomic number Z is the number of protons. Mass number A is the sum of protons and neutrons. Here, 40 is the mass number. We can deduce that number of protons equals number of electrons if the atom is electrically neutral.

Thus, atomic number helps to detect the number of electrons present. For electrically neutral atoms, this equals the number of electrons, which is unique for every element. On the other hand, the number of neutrons is not restricted by the number of protons or electrons, so the mass number of an element can vary. It indicates the chemical identity of the atom.

A is the mass number. It is the number of protons plus the number of neutrons. Z is the atomic number. It is the number of protons. Atoms and the Periodic Table Solution: The mass number A is the total number of neutrons and protons present in the nucleus of an atom of an element.

The number of protons in the nucleus of an atom is the atomic number Z. The atomic number Z of iron is 26 see inside front cover of the text. The in Pu is the mass number. The atomic number Z of plutonium is 94 see inside front cover of the text. The superscript denotes the mass number A and the subscript denotes the atomic number Z.

The atomic number is 3, so there are 3 protons. The atomic number is 13, so there are 13 protons. The atomic number is 23, so there are 23 protons.

The atomic number is 34, so there are 34 protons. The atomic number is 77, so there are 77 protons. Since all the atoms are neutral, the number of electrons is equal to the number of protons. The atomic number is 8, so there are 8 protons. The number of electrons equals the number of protons, so there are 8 electrons. The atomic number is 14, so there are 14 protons.

The number of electrons equals the number of protons, so there are 14 electrons. The atomic number is 28, so there are 28 protons. The number of electrons equals the number of protons, so there are 28 electrons. The atomic number is 39, so there are 39 protons. The number of electrons equals the number of protons, so there are 39 electrons.

The atomic number is 73, so there are 73 protons. The number of electrons equals the number of protons, so there are 73 electrons. The atomic number is 81, so there are 81 protons.

The number of electrons equals the number of protons, so there are 81 electrons. The atomic number Z can be found on the periodic table.

The atomic number of beryllium Be is 4, so there are 4 protons. The atomic number of sodium Na is 11, so there are 11 protons. Atoms and the Periodic Table 2 c.

The atomic number of selenium Se is 34, so there are 34 protons. The atomic number of gold Au is 79, so there are 79 protons. The atomic number of chlorine Cl is 17, so there are 17 protons. The atomic number of phosphorus P is 15, so there are 15 protons.

The atomic number of antimony Sb is 51, so there are 51 protons. The atomic number of palladium Pd is 46, so there are 46 protons.

The number of protons Z is the atomic number found in the periodic table. These numbers are called magic numbers. Nuclei with even numbers of both protons and neutrons are generally more stable than those with odd numbers of these particles. All isotopes of the elements with atomic numbers greater than 83 are radioactive.

All isotopes of technetium and promethium are radioactive. Most radioactive nuclei lie outside this belt.

In the case of 2 He , there are two protons but no neutrons. We first convert the mass in amu to grams. Then, assuming the nucleus to be spherical, we calculate its volume. Dividing mass by volume gives density. The mass is: The following rules are useful in predicting nuclear stability. Lithium-9 should be less stable. Sodium is less stable.

Its neutron-to-proton ratio is too high. Scandium is less stable because of odd numbers of protons and neutrons. Therefore, the elements with even atomic numbers are more likely to be stable. These elements are nickel Ni , selenium Se , and cadmium Cd. Neon should be radioactive. Actually this isotope is radioactive. All technetium isotopes are radioactive. Mercury should be radioactive.

Mercury has an even number of both neutrons and protons. Atoms and the Periodic Table 13 38 b. All curium isotopes are unstable. Bismuth is on the edge of the belt of stability, so either it is stable or it has a very long half-life. Recent investigations show that bismuth has a half-life of approximately 1. Every element is a mixture of isotopes. The atomic mass of every element on the periodic table, including carbon, is the weighted average mass of the relative abundance of each isotope.

Each isotope contributes to the average atomic mass based on its relative abundance. Multiplying the mass of each isotope by its fractional abundance percent value divided by will give its contribution to the average atomic mass. Each percent abundance must be converted to a fractional abundance: Once we find the contribution to the average atomic mass for each isotope, we can then add the contributions together to obtain the average atomic mass.

Multiplying the mass of an isotope by its fractional abundance percent value divided by will give the contribution to the average atomic mass of that particular isotope. It would seem that there are two unknowns in this problem, the fractional abundance of Tl and the fractional abundance of Tl. However, these two quantities are not independent of each other; they are related by the fact that they must sum to 1.

Start by letting x be the fractional abundance of Tl. Since the sum of the two fractional abundances must be 1, the fractional abundance of Tl is 1 — x. The fractional abundances of the two isotopes of Tl must add to 1.
