The amount of electrons. Electrons fill according to occupying the lowest energy state, and also by not spin pairing until each suborbital of same energy has one electron in each. Beware when entering the d orbitals, i.e. Cr and Cu, they will prefer to fill 4s1,3d5 and 4s1,3d10 respectively as this is more satisfying in being the lowest energy state.

Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled and why?
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
What does t he energy levels of an atom hold?
The energy levels of an atom hold electrons.
What is the neutral atom that has the first two energy levels filled and has 4 electrons in its third energy level?
You appear to mean silicon. Please see the link.
What is an electron that is in the highest energy level of an atom and determines the atom's chemical properties is called?
valence electrons
When an atom has one or more electrons in higher energy levels?
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled?
the one that is completely filled
What is the neutral atom that has its first two energy levels filled has 6 electrons in its third energy level and has no other electrons?
What is the neutral atom that has its first two energy levels filled, has 5 electrons in its third energy level, and has no other electrons? Enter the name of the element, not the abbreviation.
What atom has its first three energy levels which are fully occupied by electrons?
Neon has the 1s2, 2s2, and 2p6 levels filled.
How are the energy levels filled with electrons for a phosphorus atom?
1s2 2s2 2p6 3s2 3p3
How many elecrtons shells would be filled by a neutral xenon atom?
The first 3 energy levels are filled, the 4s and 4p and 4d sublevels are filled, and the 5s and 5p sublevels are also filled. So only the first three energy levels are completely filled. The fourth and fifth energy levels are partly filled. The electron configuration is 1s22s22p63s23p63d104s24p64d105s25p6 or [Kr]4d105s25p6.
What is the neutral atom that has its first two energy levels filled has 1 electrons in its third energy level and has no other electrons?
Sodium

If s and p sub levels of an atom of an element in period 3 are filled with electrons which orbitals are filled in this atom?
The Third
What is the neutral atom that has its first two energy levels filled has 5 electrons in its third energy level and has no other electrons?
Phosphorus, I think. Please see the link.
Determines the level that the electrons occupy in an atom?
