(a)
Interpretation:
The name of the parent
Concept introduction:
In the periodic table, the elements occupy a specific position based on their
The formula to calculate the mass number of an element is,
(b)
Interpretation:
The name of the parent atom, mass number, group and period numbers of the ionic depiction is to be determined.
Concept introduction:
In the periodic table, the elements occupy a specific position based on their atomic numbers. Elements with similar properties are placed in proximity to each other. The atomic number is the number of protons in the element. The mass number of an element is the sum of the protons and neutrons present in the nucleus of the atom.
The formula to calculate the mass number of an element is,
(c)
Interpretation:
The name of the parent atom, mass number, group and period numbers of the ionic depiction is to be determined.
