electrons. Ions exist when an atom gains or loses electrons
Charge
An isotope has extra or fewer neutrons in the nucleus than the average number for that element. This may or may not result in a radioactive isotope. An ion has extra or fewer electrons orbiting the nucleus. This usually increases the chemical reactivity.

Sr, Strontium (atom no. 38)
A neutral atom differs in charge from a positive or negative ion.
There 38 protons in strontium. Strontium is No. 38 in the Periodic Table.. This indicates the number of protons and electrons in a neutral atom of strontium . Strontium is named after the Scottish village, Strontian, in the Highlands of Scotland, where it was first discovered.
Strontium can have a full electron shell noble gas state if it loses two of it's electrons.

38
The nuclear atom differs from the uniform sphere model, because they both are made from different atoms because of the elements.
The neutral atom of strontium has 38 electrons.
