How many valence electrons does a Strontium Sr atom have

Valence electrons are electrons that are present in the outermost shell, The chemical symbol of Strontium Sr, It is a very reactive chemical that is often silver-white yellowish in color, Strontium is a chemical element that belongs to the group two element on the periodic table, The strontium has 2 valence electrons because it has 2 atoms in the 5 orbit of the shell, which makes the remaining

How to write the electron configuration for Strontium Sr

In order to write the Sr electron configuration we first need to know the number of electrons for the Sr atom there are 38 electrons, When we write the c

What is the electron configuration of Sr2+?

Strontium is atomic number 38 so its electron configuration can be written: 2,8,18,8,2, In orbital notation this is: 1s22s22p63s23p63d104s24p65s2, The noble gas shorthand notation is: [Kr]5s2, When strontium forms a 2+ ion the 2 outer 5s electrons are lost so Sr2+ can be written as: 1s22s22p63s23p63d104s24p6,
