Question

How many protons, neutrons, and electrons does Sr^2+

Answer 1

38 protons 36 electrons 30 neutron because of 29 isotope

Answer 2

36 electrons

Step-by-step explanation:

The # of protons is always equal to the atomic number. In the case of Sr (Strontium), it is 38 protons.

The 2+ at the end means that it has a charge of +2, meaning that it LOST two electrons to become a cation with a full valence shell. So, 38 - 2 = 36 electrons
