How many valence electrons does a Strontium (Sr) atom have?

A strontium atom has 2 valence electrons, which are located on the outermost shell of the strontium. 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 36 seen as internal. The electron configuration of Strontium is

1s22s22p63s23p63d104s24p65s2 or it can also be represented as [Kr] 5s2. The atomic number is 38, and the Atomic mass is 87.62 u

Strontium is a chemical element. It is metal, which is soft and silver. Strontium has several uses. One important use is that it blocks X-rays that TV tubes emit. Strontium is also what allows glow-in-the-dark paint to do what its name says.

One use that all will be familiar with is related to fireworks. The color red that we sell in fireworks is Strontium. It is highly reactive and is the 15th most abundant element on Earth. Its atomic number is 38, and the symbol is Sr. When Strontium is at room temperature, it is solid.
