Hydrogen can hold only 1 electron.
Hydrogen has one electron. Its outer shell the first energy level has just one orbital, 1s which could hold a maximum of 2 electrons, so hydrogen only partially fills the level.
Yes, hydrogen can fill its outer shell with two electrons. Hydrogen has one electron in its first shell, so by gaining one more electron it can achieve a stable configuration with two electrons in its outer shell.
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
4 electrons are required to fill the outer shell of a carbon atom. This, the second shell of carbon, can contain two 2s electrons and six 2p electrons, but in a neutral carbon atom it actually contains only two 2s electrons and two 2p electrons. Therefore, four more electrons are required to fill the outer shell.
An atom of nitrogen has 5 electrons in its outer shell. This makes nitrogen a nonmetal and means it requires 3 more electrons to fill its outer shell and become stable.
Two electrons will fill a hydrogen's outer, or valence, shell.
Hydrogen has one electron. Its outer shell the first energy level has just one orbital, 1s which could hold a maximum of 2 electrons, so hydrogen only partially fills the level.
Yes, hydrogen can fill its outer shell with two electrons. Hydrogen has one electron in its first shell, so by gaining one more electron it can achieve a stable configuration with two electrons in its outer shell.
Not by itself, no (that is, hydrogen is not a noble gas). A neutral hydrogen atom starts out with 1 electron, but it needs 2 electrons to fill its shell. Therefore, a hydrogen atom will often form 1 covalent bond with another atom, in order to gain that 1 extra electron it needs to fill its shell. Important note: Most elements need 8 electrons to get a full shell, but hydrogen is the exception: it only needs 2 electrons to get a full shell.
Sulfur has 6 electrons in its outer shell. Therefore, it needs 2 more electrons to fill its outer shell.
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
There is only one electron inhabiting hydrogen and the compound therefore only has one shell, effectively making that shell the outer shell. TL;DR There is 1 electron in the outer shell of hydrogen.
Nitrogen needs 3 more electrons to fill its outer shell. It has 5 electrons in its outer shell, and it typically needs a total of 8 electrons to achieve a full outer shell (octet rule).
Carbon needs 4 electrons to fill up its outer shell. It has 4 valence electrons and can achieve a full octet by gaining 4 more electrons.
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
