Why atomic radius remains almost unchanged as you move through period 2 from group 14 to 18?

Electrons are all being added to the same "p" sublevel so no new energy levels are being added. Actually as you go across the size will decrease slightly due to the increase in the charge of the nucleus.

What happens to an atomic level when an element melts?
The atomic level is unchanged.
When an unstable isotope breaks down but doesn't change to another element the atomic number always?
The atomic number is unchanged.
Which sub-atomic particle cannot change?
The sub-atomic particles does not change is electron. Electron not remains negatively charged but its mass remains the same too.
What is the atomic mass of a diamond?
As diamonds are almost pure carbon, the atomic mass would be carbon's atomic mass: 12.0107
What is the atomic number for CH3?
Atomic number remains same for another isotope but only mass number changes. So it will be 1
What happens to an atomic level when an element melts?
The atomic level is unchanged.
What happend to the atomic number of an element which emits alpha particle and two beta particle?
THe atomic number would decrease by 2 as alpha particle comes out. But for two beta particles the atomic number would increase by 2. So the atomic number remains unchanged due to emission of one alpha followed by 2 beta particles.
Does an atomic increase through gamma radiation?
it remains the same gamma rays have no mass and no electrical charge
When an unstable isotope breaks down but doesn't change to another element the atomic number always?
The atomic number is unchanged.
What is the atomic name for oxygen?
It remains "oxygen."
Which sub-atomic particle cannot change?
The sub-atomic particles does not change is electron. Electron not remains negatively charged but its mass remains the same too.

As diamonds are almost pure carbon, the atomic mass would be carbon's atomic mass: 12.0107
What change in atomic mass when an atom emits gamma radiation?
It remains the same.
What is the atomic number for CH3?
Atomic number remains same for another isotope but only mass number changes. So it will be 1
Ask us happens at the atomic level when a metal is subjected to pressure such as a blow from a hammer?
The atom remain unchanged but the arrangement of atoms in the lattice is modified.
What happen to atomic number and mass number of nucleus when it emits electron?
"Number" goes up by one, mass stays the same.
What happens when a radioactive isotope decays?
It emits an electron and an antineutrino and increases by one in atomic number while ending up with one fewer neutrons, or it emits a positron and a neutrino and decreases by one in atomic number while ending up with one more neutron. In both cases the total number of protons and neutrons remains unchanged, and the number of orbital electrons will eventually change to match the new atomic number.
