Question

What is the number of protons housed in the nucleus?

Answer 1

The number of protons housed in the nucleus gives `Z`, `"the atomic number.........."`

Explanation:

`Z` gives the number of positively charged, massive particles present in the nucleus (what do we call these?). And `Z` gives the identity of the atom absolutely:

`"Z=1, the element is hydrogen........."`

`"Z=2, the element is helium........."`

`"Z=3, the element is lithium........."`

`"Z=4, the element is beryllium........."`

`"Z=25, the element is manganese........."`

`"Z=92, the element is uranium........."`

For a given element, say manganese, how many electrons are present in the neutral atom? You should be able to answer this pdq.
