Chapter 2, Problem 2.142P

(a)

Interpretation Introduction

Interpretation:

The name, symbol, atomic number, atomic mass, period number and group number of all the elements present in the red building-block is to be determined.

Concept introduction:

The mass of one mole of a substance in grams is called molar mass. The S.I unit of molar mass is $\text{g/mol}$.

The molar mass of an element is equal to the mass of $6.023\times {10}^{23}$ atoms. The molar mass of an element can be determined from the periodic table.

The general representation for an atom is given as ${}_Z^A\text{X}$. Here, $A$ is a mass number and $Z$ is the atomic number of an atom.

The atomic number is equal to the number of protons present in an atom.

The atomic mass equals to the sum of a number of proton and neutron in an atom.
