Answer:

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.
