What element's neutral atoms have 20 protons?
The atomic number of this atom should be 20. The element is potassium. Its electron configuration is [Ar] 4s2.
What is the difference between a neutron and a nucleus?
Well a neutron and a nucleus are different from each other because a neutron is a particle within the atom nucleus with a neutral charge The nucleus however is all the neutrons and the protons. Nucleus could also mean the nucleus of a cell, which is commonly refered to as well, but is completely different.
Why are electrons in the 1s subshell much closer to the nucleus in Ar than in He?
It is due to the increased in the effective nuclear charge in argon. Helium has 2 protons in its nucleus. On the other hand, argon has 18 protons in its nucleus.Therefore, it has greater attractive power. Due to this, all the electrons are pulled closer to nucleus.
Which of these is not a fundamental subatomic unit of an element protons nucleus electrons neutrons?
Protons and neutrons ar fomed from quarks and are not considered as fundamental particles; they are components of the atomic nucleus.
