Ammonia is made for one nitrogen atom and three hydrogen atoms.
Ten, in all.
Nonmetals become stable by gaining or sharing enough valence electrons to have a set of eight valence electrons in a shell or energy level
Atoms that are neutrally charged will have the same number of protons as electrons, because one proton will cancel out one electron. To achieve a net charge of 0, 12 protons must be countered with 12 electrons.
====================================== My explaination will be Carbon,the non-metal element that contains of 6electrons,2.4 .....the positive charge 4 valenced electrons will share its electron with 2 oxygen atoms that consists of 4 valenced electrons too,in order to achieve stable octet electron arrangement,thus CO2 is formed
On the periodic table, there are periods that are rows, and groups that are columns. Elements in the same group react like the other elements in the group.
An electron moving towards the nucleus slows down and any energy it contains from a higher shelf is released.
nitrogen has 5 valence electrons. It should gain 3 electrons to achieve a noble gas configuration.
Nitrogen has to gain three electrons
By gaining 3 electrons
Nitrogen must gain three electrons.
nitrogen should give 5 electrons (or better gain 3 electrons) to attain noble gas configuration.
3
it has to gain 3
-3 charge. Nitrogen has to gain three electrons to achieve the noble gas configuration of neon, so it will have -3 charge (as in N3- ion or nitride ion)
carbon and nitrogen atoms form covalent bonds with one another in order to achieve an octet (8) of valence electrons between them.
Magnesium is group II and has two valance electrons to donate to achieve the octet state. Nitrogen has 5 valance electrons so it accepts 3 into its outer shell to make an octet. So Mg3N2
The nitride ion, N3­­­ˉ, has an electron arrangement of 1s2, 2s2, 2p6 The elemental nitrogen, N, has an electron arrangement of 1s2, 2s2, 2p3. Since the nitride ion, N3-, has 3 extra electons, those 3 extra electrons fill the 2p orbital giving the electron arrangement above. This stabilizes the nitride ion because it is similar to a noble gas.
The reason why nitrogen isn't inert is due to the layout of electrons around the nucleus. the electrons are found in layers/shells. For all elements except the noble gases the outer most shell is incomplete. Having a complete outer shell is the most stable any atom will get as it requires massive quantities of energy to remove them. The noble gases have full outer shells and this is why they are inert. All the other elements try to achieve this state. I will use nitrogen as an example. Nitrogen has 5 electrons in its outer most shell. The closest noble gas is Neon with 8 electrons in its outer shell. For nitrogen to achieve a full outer shell it needs 3 more electrons which it will find through bonding to other elements. Basically put nitrogen isn't inert because it will react with other elements to try and achieve a full outer shell of 8 electrons.
