Question

the radius of sodium atom is 2.44×10-⁸ mm. the radius of oxygen atom is 1.22×10-⁵ mm. compare the radius of oxygen atom to sodium atom​

Answer 1

Answer:

radius of O = 2.44×10-⁸

radius of Na = 1.22×10-⁵

Or/Na r = 2.44×10-⁸ / 1.22×10-⁵

= 2×10-³

Radius of oxygen atom is 2×10-³ time higher than radius of sodium atom
