To find the number of atoms in 1 gram of boron, we first need to know its molar mass, which is approximately 10.81 grams per mole. Using Avogadro's number, which is about (6.022 \times 10^{23}) atoms per mole, we can calculate the number of atoms in 1 gram of boron. The number of moles in 1 gram is (1 , \text{g} / 10.81 , \text{g/mol} \approx 0.0925 , \text{moles}). Thus, the number of atoms is approximately (0.0925 \times 6.022 \times 10^{23} \approx 5.57 \times 10^{22}) atoms.

An electrically neutral atom of boron has 5 electrons. This is because the number of electrons in a neutral atom equals the number of protons, and boron has an atomic number of 5, indicating it has 5 protons. Therefore, to maintain electrical neutrality, it also has 5 electrons.
