Which list of elements shows increasing atomic size, from
smallest to largest.
o be, mg, ca, sr
o
k, ca, cr, co
o xe, kr, ai, ne
ai, si, p, s

The answer is one of two options

K, Ca, Cr, Co

or

Ai, Si, P, S

Explanation:

For one look at a periodic table

But how you get the answer is by looking at the atomic number that is how many protons and electrons are in the atom ex: Oxygen or O has a atomic number of 8 because it has EXACTLY 8 protons and EXACTLY 8 electrons.

Now the reason I put two answers is because if it has to be a perfect line with no elements in between it is the second choice

But if it doesn't it can be either or.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
