【2 Steps】How Many Protons Does Beryllium Have?||Number of Protons in Beryllium||Atomic Number of Beryllium

How Many Protons Does Beryllium  Have?||Number of Protons in Beryllium

First,we have to look for the symbol for beryllium in the  periodic table.

From the periodic table,we see that the symbol for beryllium is Be.Look at IIA group .

                Step-2:

Now we will look at the number situated upper right of the beryllium element's symbol. 

From periodic table ,we observe that  this number for beryllium is 4.This number is called atomic number and expresses the number of protons in the beryllium's element.So there are four protons in beryllium.

                 

Nice to know:

Remember that the atomic number of beryllium is 4.This means that in a neutral beryllium atom we have four protons and four electrons.

As the charge of proton is +1 and  the charge of electron is -1,equal number of protons and electrons make a beryllium atom neutral or chargeless
