Question

An element has atomic number 11 and a mass number 23 how many numbers of neutrons protons electrons does it have

Answer 1

No. Of protons =no. Of electrons =atomic no. =11
No.of neutrons=mass no. - atomic no. =23-11=12

Hope this helps
And if it helped please mark as brainliest

Answer 2

Here is your answer

Atomic number of element is 11
So, it will have 11 protons in its nucleus
No. of protons= no. of electrons in an element
So, no. of electrons= 11

Atomic mass= proton+neutron
so, a/q--- 23= 11+ n
n= 23-11= 12
no. of neutrons= 12
