The strontium ion is Sr2+ with the same electron configuration as Kr. Sr element has an atomic number of 38- the neutrl Sr tom has 38 protons in its nucleus and 38 electrons - therefore the ion Sr2+ has 2 less - 36.

The strontium ion, Sr^2+, would have 36 electrons. This is because a neutral strontium atom has 38 electrons, but when it loses 2 electrons to become an ion, its electron count decreases to 36.
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.
Strontium will lose 2 electrons to form a 2+ ion.
The strontium ion is called the Sr2+ ion. It has a 2+ charge due to the loss of two electrons from a neutral strontium atom.
A strontium atom is neutral, meaning it has an equal number of protons and electrons. A strontium ion, on the other hand, has lost or gained electrons, resulting in a positive or negative charge, respectively.
Strontium, element with atomic number 38, will lose 2 electrons to form a stable ion as it tends to lose electrons to attain a noble gas configuration.
