Concept explainers
(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
(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.
(c)
Interpretation:
The electronic configuration for the element Zinc needs to be written and the electrons which are lost in the formation of
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.
