Question

4. The size of an atom is determined by its.​

Answer 1

Explanation:

Every atom is different in its number of protons, its mass, and its size. The size of the atoms is determined by the size of their orbitals. The larger the quantum number "n" is, the larger the orbital is, which increases the size of the atom

Answer 2

• The number of protons, mass, and size of each atom are all unique.
• The size of the orbitals of the atoms determines their size.
• The bigger the quantum number "n," the larger the orbital, and hence the atom's size grows.

• We can't quantify the size of an isolated atom since we can't tell where the electrons that surround the nucleus are.
• However, we may determine an atom's size by assuming that an atom's radius is half the distance between neighbouring atoms in a solid.
• Metals, which produce solids made of extended planes of atoms of that element, are most suited to this approach.
• As a result, the findings of these measurements are frequently referred to as metallic radii.
