Which change is likely to happen to an atom of the element strontium (Sr) during bonding?
It will give up electrons, forming a negative ion.
It will gain electrons, forming a negative ion.
It will gain electrons, forming a positive ion.
It will give up electrons, forming a positive ion.

Well, let me put on my clown nose for this one! When strontium (Sr) bonds with another element, it does a little electron dance. And guess what? It loves to boogie by giving up electrons, forming a positive ion! So, Strontium likes to strut its stuff and become a positively charged ion! Keep on grooving, strontium!
To understand how an atom of the element strontium (Sr) behaves during bonding, we need to consider its position on the periodic table. Strontium is located in Group 2, which means it has two valence electrons in its outermost energy level.
When atoms form chemical bonds, they do so to achieve a more stable electron configuration, usually by either gaining or losing electrons from their outermost energy levels. In the case of strontium, it is easier for the atom to lose its two valence electrons rather than gain six more to fill its energy level.
Therefore, the correct answer is:
It will give up electrons, forming a positive ion.
By giving up its two valence electrons, the strontium atom becomes a positively charged ion, known as a cation. This ion will have a 2+ charge because it now has two more protons (positive charges) than electrons (negative charges).
SrCl2 is strontium chloride
Sr++ and 2 Cl-
Sr gave up an electron to each Cl atom becoming positively charged since it now has 2 more protons than electrons.
