It is in the same row as sodium on the periodic table
It is in the same column as sodium on the periodic table
It had one more proton than sodium
It has an equal number of protons as sodium

Answer 1

It is in the same column as sodium on the periodic table.

Step-by-step explanation:

Answer 2

I think it's in the same column as a sodium on the periodic table because chemical properties are based on their electron structure and the columns called groups are elements with the same shell structure which increases in mass as you go down the column, therefore the elements which are similar to sodium must be in the same group.
