What is the ionic formula of nitrogen and magnesium?
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
What are valanced electrons?
Good Question Valance electrons are simply the number of electrons in the outer shell of an atom. An easy way to figure this out is to look at the families (the vertical columns of the Periodic Table) and count over from left to right. The number in the ones place is the number of valance electrons that the element will have. The goal is usually to fill the number of valance electrons using the octet rule. The octet rule is filling it to its max so it becomes stable the number is usually eight. There are some exceptions such as helium which has two.
How does the octet rule relate how active an element is?
The octet rule states that all elements form ions to reach 8 valance electrons, or the nearest noble gas. If an element is a noble gas, it already has 8 valance electrons, therefore does not need to form ions to bond with other ions, thus becoming un-reactive.
What rule is it when representative elements form bonds until they have eight electrons in their valance shells?
The octet rule also known as the rule of eight
How many valence electrons do alkali metals lose to obtain an octet?
they lose one electron
Do ions have an unusual number of electrons?
Cations donate electrons from their valance shell, have less, to reach their octet state. Anions accept electrons into their valance shell, have more, to reach their octet state.
Why is Zn not anoble gas?
It's valance shell does not contain an octet of eight valance electrons. That simple.
Is argon a reactive element?
Not really. Argon is a Nobel gas with a full valance octet; 8 valance electrons that do not need to accept or donate electrons to be '' happy. ''
What makes a group not reactive on the periodic table?
A full octet, valance shell. A valance shell with eight electrons, such as the Nobel gases have, doe not need to donate or accept electrons into or out of the valance shell to be stable.
How many valance electrons does the oxygen have?
six valence electrons.....It only requires two more to complete octet....
What is the ionic formula of nitrogen and magnesium?
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
How many more electrons does silicon need in order to have a stable octet?
Silicon, like carbon, has four valance electrons, and needs another four to have a stable octet.
How is the reactivity of elements related to valence electrons in atoms?
Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.
Chemical bonds have what kind of electrons?
well when chemical bond for them to be stable they have to form a octet where all the valance electrons add up to 8.
Why noble gases require the group 8 in the periodic table?
They have a perfect octet of valance electrons; eight in number.
Is chlorine an electron doner or an acceptor?
Chlorine has 7 valance electrons so the easiest way for it to fill it's valance shell and have an octet is to be an electron acceptor; an anion.
Does oxygen give its electrons away?
No, oxygen is a strong electron acceptor and accepts two electrons into it's valance shell to complete it's octet.
