Please answer true or false I will submit if it's right you get brainliest

True

Explanation:

The number of valence electrons governs its bonding behavior (octet rule).

yes, The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table

Explanation:

hope this helps sorry if incorrect have a good rest of your day :) ❤

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
