Hydrogen need 1 more electron to fill outermost orbit. Then, H will act as anion.
The outermost ring of hydrogen, or the first energy level, can only hold a maximum of 2 electrons.
When these elements have five electrons on the outermost shell of electrons.
Selenium needs two more electrons.
Two electrons will fill a hydrogen's outer, or valence, shell.
Hydrogen has one electron and needs one more. Helium has two electrons and has filled shell. Carbon needs four more electrons to fill the valence shell Oxygen needs two more electrons to fill the valence shell
Helium already has a full valence shell. Because the first orbital holds two, and the second orbital holds eight...Helium is already filling the first shell with its two electrons, and it has no more electrons to spill into the second orbital, therefore it's one and only shell is full. Hydrogen tends to gain one electron in order to fill its outermost energy level. Hydrogen only has one, but it needs two to fill it's valence shell, so it will gain one. Long story short, helium is already full (that's why it's in the noble gas group) and hydrogen tends to gain one electron, and form a negative ion. No honey it has a number and that is 2 duh!!
1: The outermost ring of hydrogen is the s-level, which can contain only two electrons, and a hydrogen atom itself already has one of these electrons.
Chlorine is MUCH more likely to fill its outermost orbital by gaining electrons.
It would gain 2 electrons.
Atoms can fill their outermost energy level by either gaining electrons from other atoms or by sharing the outermost electrons with another atom.
This value could vary from element to element and atoms could have 1 to 8 valence electrons.
The outermost energy level of an atom typically has between 1 and 8 electrons.
8
When these elements have five electrons on the outermost shell of electrons.
It is the most stable element in the universe and does not need anymore electrons. Its outermost energy level is full.
The sharing of electrons occurs in covalent bonding.
Covalent Bonds. :)
no!
