Strontium ion has 0 electrons in its outer shell because it has lost two electrons to become stable. In its neutral state, strontium (Sr) has 2 electrons in its outer shell.
Usually three will be lost.
There are no unpaired electrons in strontium.
Strontium is a metal element. There are 87 electrons in a single atom.
Only three electrons.

There are no unpaired electrons in strontium.
There is zero NET loss or gain of electrons
Strontium is a metal element. There are 87 electrons in a single atom.
You can determine how many electrons are gained or lost by looking at the atom's charge. If the atom gains electrons, it becomes negatively charged; if it loses electrons, it becomes positively charged. The difference between the atom's original and final charge tells you how many electrons were gained or lost.
Only three electrons.
There are 2 electrons in the outermost shell of strontium. Strontium has an electron configuration of [Kr] 5s^2, indicating that it has two electrons in its outermost shell.
Strontium has 38 electrons.
the oxidation number
Strontium has 38 electrons. (Protons and electrons are the same)
Strontium has 2 valence electrons. It is in group 2 of the periodic table, which means it has 2 electrons in its outermost energy level.
