What is an atom shell?
electron shells are like the orbits of electrons around the protons and neutrons the atoms can have 1-3 shells
How many electrons would be expected in the outer most shell of an atom with an atomic number of 10?
Given what we know about electron structure, we would expect there to be 8 electrons in the outer shell of an atom with the atomic number of 10. And that's how many there are. Element 10 is neon, and like all noble or inert gases, it has a full outer shell.There are only two electron shells for all the elements up through element 10 (neon). The first shell will only accept 2 electrons. That's the s shell, and it's the outer shell (and the only shell) for helium (the lightest inert gas). The next 8 electrons will fill the second electron shell, which is the p shell. That means element 10 (the inert gas neon) will have a full s shell (2 electrons) and a full p shell (8 electrons).
An atom of element X has two outer electrons that do not fill the outer shell is it a metal?
It would be a non-metal and a halogen. Group 18 or the noble gases, all have 8 electrons in their outer shell. Therefore, the group before it would have seven electrons in the outer shell. This group is made up of all non-metals.
An atom of argon rarely bonds to an atom of another element because an argon atom has what?
Atoms of argon have a full outer (valence) shell, and this is why argon is inert. The electrons of an atom have different energy levels. It's conventional to call each collection of possible states of electrons for a given energy level a shell. Shells have finite capacity and argon has a full outer shell. Chemical reactions tend to rely on electrons jumping from one atom to another or two sharing the orbit of 2 electrons (a type of shell around 2 electrons if you like). If the shells are full it is usually more energy efficient for an electron to stay put rather than jump to another atom. consequently argon with its full shells rarely bonds.
Electrons are located in?
Electrons, unlike neutrons and protons, are not located in the nucleus. Instead, they orbit around the nucleus. It's kinda like the moon orbiting the Earth.
Why is sulfur atom similar to oxygen atom?
Because it has 6 electrons in its outer shell, just like oxygen.

Why is O the element symbol for oxygen?
A lone oxygen atom has 6 outer shell or valence electrons but like other atoms, is most stable with a full outer shell of 8 electrons. In order to get this full outer shell, the oxygen atoms shares electrons with another atom, this is called a covalent bond. In the O2 molecule there are two oxygen atoms bonded together. Each atom contributes 2 electrons to be shared between both atoms, allowing each atom to achieve a full outer shell.
Is an atom that has six electrons stable?
No, an atom with six electrons will try to react with another atom to gain two more electrons. Actually the fewer electrons the atom needs the more reactive it will be unless it has exactly eight valence electrons in its outer shell like a noble gas(He, Ne, Ar, etc.) Hope this helps!

How are valence electrons imoprtant?
Valence electrons can determine the reactivity of the atom. An atom with a full shell of valence electrons, like neon, will be less reactive than an atom with only one electron in its valence shell, like sodium.
How many electrons does the element silicon have in its outer shell?
Silicon (or Silicium) has 4 electrons in its outer shell, just like Carbon, Germanium, Tin and Lead.
What term is used for the electrons in the outermost shell?
there called valence electrons

Why do hydrogen like to make covalent bond?
Each hydrogen atom has one electron on its outer shell. The first electronic shell of any element can only hold 2 electrons, this means that each hydrogen atom needs one electron. 2 hydrogen atoms 'share' their electrons with each other, this can be shown on a dot and cross diagram. Each hydrogen now has 2 electrons on their outer shell and they have become stable. ;)

What does the number of electrons in the outer energy level of an atom indicate about the element?
What it bonds with. If you have a noble gas (like Krypton), since its outer energy level is full, it won't bond with anything. But if you have Hydrogen, who has one electron in the outermost level, it can bond with any other element with enough space on it's outermost energy level.
