Chapter 3, Problem 79P

Interpretation Introduction

(a)

Interpretation:

The number of protons and electrons in neutral zinc atom needs to be determined.

Concept introduction:

In an atom, number of protons and electrons can be calculated from atomic number and mass number. The atomic number is equal to the number of protons and electrons present in the neutral atom. The mass number is sum of number of neutrons and protons in the nucleus of an atom.

Interpretation Introduction

(b)

Interpretation:

The number of protons and electrons in Zn²⁺ ion needs to be determined.

Concept introduction:

In an atom, number of protons and electrons can be calculated from atomic number and mass number. The atomic number is equal to the number of protons and electrons present in the neutral atom. The mass number is sum of number of neutrons and protons in the nucleus of an atom. The positive and negative ions are formed due to difference in the number of protons and electrons in an atom. If number of electrons is more, the ion will be negatively charged and if number of protons is more, the ion will be positively charged.

Interpretation Introduction

(c)

Interpretation:

The electronic configuration for the element Zinc needs to be written and the electrons which are lost in the formation of Zn2+ needs to be identified.

Concept introduction:

Electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals. This helps to indicate electrons and orbitals easily.

Answer true or false. (a) The octet rule refers to the chemical bonding patterns of the first eight elements of the Periodic Table. (b) The octet rule refers to the tendency of certain elements to react in such a way that they achieve an outer shell of eight valence electrons. (c) In gaining electrons, an atom becomes a positively charged ion called a cation. (d) When an atom forms an ion, only the number of valence electrons changes; the number of protons and neutrons in the nucleus does not change. (e) In forming ions, Group 2A elements typically lose two electrons to become cations with a charge of 12. (f) In forming an ion, a sodium atom (1s22s22p63s1) completes its valence shell by adding one electron to fill its 3s shell (1s22s22p63s2). (g) The elements of Group 6A typically react by ac- cepting two electrons to become anions with a charge of 22.
