How is valence and reactivity related?
Valence electrons are the electrons on the outer shell of an atom. Valence electrons help to determine the reactivity of a substance because atoms do their best to "fill" their outer shell with 8 electrons, thus achieving a more stable energetic state. Different atoms have different numbers of valence electrons, which affects their reactivity. For instance, noble gases are inert because they possess a full set of valence electrons and don't need to "borrow" or "give away" electrons to have a full outer shell. Halogens, on the other hand, are 1 electron away from filling their outer shell, and are very reactive as a result (they attempt to "borrow" an electron with other atoms by forming a chemical bond).
How many electrons does each atom desire?
Atoms do not actually have desires as such, although the metaphor can be useful. Atoms are more stable when they have a full outer electron shell. The smaller atoms, hydrogen, helium, lithium, and beryllium, can obtain a full outer shell with only two electrons in it. The heavier atoms require 8 electrons to have a full outer shell. That is known as the octet rule (an octet is a set of eight).
Which atoms will have their outer energy level filled with 2 electrons?
There are more than two such atoms. Perhaps there was a list of atoms you had to chose from. Anyway, two such atoms are beryllium and magnesium.
Are atoms with more than 4 outer electrons are nonmetals?
No, but metals have more than three-fourths.
Atoms are more stable in their outer shell if they have?
A chemical stable atom is when it has the same number has electrons and protons. When the electrons and the protons are same it cannot react with any other atom till then and the atoms are called as inert atoms.

Why do outer shells of atoms hold more electrons?
Because the shell can only hold eight electrons. check
What is the name of an element that lends electrons?
Firstly I would like to correct you on your grammar. The question should in fact ask 'which' element gains 5 electrons. The question is also flawed form the start because more than one element gains 5 electrons. All elements in group 3 of the Periodic Table have 5 spaces in the outer shell. All elements want to feel complete, and the maximum amount of elements on the outer shell is 8. Therefore 3 + 5 = 8. So hey presto this is my answer to you. ~K :)

What if the outer orbital is not full of electrons?
If the outer orbital is not full of electrons, the atom is unstable. It will react with other atoms to fill its outer shell.
Are atoms with more than 4 outer electrons are nonmetals?
No, but metals have more than three-fourths.
How do the atoms connect to form minerals?
Chemical bonding is driven by several different mechanisms by which atoms obtain more stable arrangements of their outer electron shells. The basic rule is, complete outer shells are more stable. The smallest atoms can have complete outer shells with just two electrons (or even with zero electrons, in the case of hydrogen) but most atoms require eight electrons in the outer shell (which is known as the octet rule). Atoms can either share electrons with other atoms (forming covalent bonds or in the case of metals, metallic bonds) or exchange electrons with other atoms (forming ionic bonds). In minerals, most of the bonds are ionic. Atoms with too many electrons give excess electrons to atoms with too few electrons and they both become more stable, and also acquire electrical charges. They then attract each other, due to their electrical charges (opposite charges attract, as stated by Coulomb's Law) and that is how they connect to form minerals or other compounds.
What do electrons have to do with chemical bonds?
Each element has shells of electrons and they are limited to how many can be shared in the outer shell. This lets us know what and how many atoms can combine with it. Hydrogen has the need for one electron in its outer shell. Oxygen has the need for two more electrons in its outer shell. Therefore, 2 hydrogen atoms can combine with oxygen.
Why do some atoms gain electrons while other atoms lose electrons during ionic bonding?
The most stable electron configuration for any atom is to have a complete outer shell. For the smallest atoms, that can be no electrons at all (for H+) since no shell is equivalent to a complete shell, or just two electrons in the outer shell, such as for a helium atom, but for most elements that means 8 electrons in the outer shell. We then have atoms which have five or more electrons in their outer shell and therefore need three or less to complete their shell, and they tend to gain electrons because it is easier to gain three than it is to lose five. Similarly, there are atoms with three or fewer electrons in their outer shell, and they tend to lose electrons because it is easier to lose three than it is to gain five. In the middle we have an atom such as carbon, with four electrons it its outer shell; it can gain or lose electrons with equal ease.
Why do atoms share gain or lose electrons?
Atoms gain, share, or lose electrons to try and become more stable. Atoms will gain, share, or lose electrons until they have a stable 8 valence electrons in their outer shell which is called an octet, which is stated in the octet rule. See the attached links for information on the octet rule.
Why does nitrogen not bond to more then 4 other atoms?
Nitrogen only bonds to three other atoms because its outer shell contains five electrons. An atom is most stable when it has eight electrons in its outer shell, and it can get there either by owning eight electrons of its own, like a noble gas does, or by sharing electrons with other atoms, like you see when nitrogen bonds to three hydrogen atoms to form ammonia.
