Each electron in an atom has a charge of -1 , and each proton has a charge of +1 . What is the overral charge of an atom that cointains 2 eletrons and 2 protons

0

Step-by-step explanation:

It would be the same as adding 2 to 0 then taking the same 2 away.

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
