Which shows the correct ordering of atoms in terms of increasing size?

Question

a.) N b.) Be c.) N d.) Be

Answer 1

If you have your periodic table handy, look at the key for the table, where it will tell you which corner of each element's block has the atomic radius. You will notice that atomic radius tends to increase as you go down the rows of the table. Makes sense; More electrons means a larger atom. As you go from right to left, however, you will see that, in any one row, the radius decreases until you get to about the middle of the row; then the radius begins to increase with the atomic weight. On any row, the element at the left end (lower atomic weight) has a larger diameter than the one on the right end (higher atomic weight). All of this out of the way, Beryllium is larger than Carbon, which is in turn, larger than Nitrogen.

Answer 2

length of atoms will advance from top to left on the era and from backside to fabulous on the communities if an ion has a cost it has a similar length to the atom with that properly-known style of electrons. so Co3+/Fe2+ Fe3+

Answer 3

D
Atomic masses are:
Be=9.012, C=12.001, N=14.007

Answer 4

(D), Be-C-N The larger the atomic number the bigger the atom
