Question

An element t has total noof Proton are 18 and neutron are 20 .
Name the element ?​

Answer 1

Answer:

You gots Z=18 , the atomic number, where Z is the number of nuclear protons. The number of protons defines the element....and thus we got calcium.... ....and with 20 neutrons we got the 38Ca isotope....the which is rather short-lived

Answer 2

Explanation:

The element has total number of protons are 18 thus the number of electrons will be 18

Here the number of neutron is 20 so the atomic mass of elements = 18 + 20 = 38

So the element is Argon.
