How many electrons does the valance shell in hydrogen have?
1
How many shells are in hydrogen?
Hydrogen has one shell with only 1 electron on the valance shell.
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.
Why does oxygen have more electronegativity than hydrogen?
Oxygen has more electronegativity than hydrogen because it has more protons in its nucleus, which creates a stronger positive charge to attract electrons. Additionally, oxygen is smaller in size than hydrogen, which leads to stronger electron-nucleus attraction.
Is the valance shell innermost or outtermost?
outermost
Why is Zn not anoble gas?
It's valance shell does not contain an octet of eight valance electrons. That simple.
Why does sulfur have a valency of 4 and 6 when it needs only 2 electrons for stable configuration?
It has 6 electrons in it's valance shell and needs 2 more electrons in it's valance shell to become stable. Some atoms, phosphorous for instance ( valance # 5 ), can reach deeper into their valance shell and make additional covalent bonds.
Complete valance shell holds electrons?
8
Does calcium have three electrons in its valence shell yes or no?
No. It has Two electron in its valance shell.
How many atoms in the valence shell of sodium?
There is one electron in sodium's valance shell.
Can hydrogen can be place in group 7?
No, hydrogen does not belong to group 7 of the periodic table. It is placed in group 1 since it has 1 electron in its outer shell.
Outer shell electrons are known as?
Valance electrons
