Question

What are the five typical elements with the smallest atomic radii?

Answer 1

The first five elements in the periodic table: hydrogen, helium lithium, berylium and boron.  The lower the atomic number, the smaller the radius.

Answer 2

dunno

Answer 3

The atomic radius of each element depends on both how many orbitals there are and how many protons are in the nucleus to attract the electrons to it.

Generally speaking, the more orbitals that exist, the larger the atomic radius and the more protons in the nucleus, the smaller the atomic radius.

Some atomic radii have been measured empirically, [1] however, I will supply you with the calculated values.

The smallest elements by atomic radius are [1]:

1. Helium: 31 picometres (pm)

2. Neon: 38 pm

3. Fluorine: 42 pm

4. Oxygen: 48 pm

5. Hydrogen: 53 pm
