Question

2) How does the size of the atom measured?​

Answer 1

Answer:

$\large\mathbb{\underbrace\purple{ANSWER}}$

The size of an atom is defined by the edge of its orbital. ... The units for atomic radii are picometers, equal to 10−12 meters. As an example, the internuclear distance between the two hydrogen atoms in an H2 molecule is measured to be 74 pm. Therefore, the atomic radius of a hydrogen atom is 742=37 pm 74 2 = 37 pm .

Answer 2

Answer:

The atomic radius is the size of the atom, typically measured by the distance from the nucleus of the atom to the electron clouds around the nucleus. Covalent radius can be calculated by measuring the distance between the two nucleus of two atoms in covalent compound.
