Question

which element atomic size is bigger berilium or corbon?why?​

Answer 1

Answer:

The sizes of atoms and ions are important in determining the properties of both covalent and ionic compounds. You should already have some appreciation of the factors which govern atomic sizes from the color-coded dot-density diagrams of Hydrogen, Helium, and Lithium and of Beryllium, Boron and Carbon. From the leftmost diagram below, one can see that Hydrogen seems to have a larger atomic radius than Helium, but not larger than Lithium (although it's "radius" is quite spread out). On the right side, one can see that the atomic radius steadily decreases as you go down the line. Note the relative locations of these elements on the periodic table and predict what the trend might be.

Answer 2

Answer:

it's beryllium

Explanation:

Because Beryllium comes in the group 2 and Carbon comes in the group 16 so, as the elements goes from left to right the atomic size increases and as we go down the atomic size too increases.
