Want this question answered?
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most shell.
There is one electron on cobalts outer shell.
Covalent bonds
Compounds form their shapes due to the size of the atoms and the repelling of bonding pairs of electrons. The electron pairs repel the the furthest parts of the atom that they can(It's easier if you imagine the atom's outer shell as a sphere, where the electron pairs are as far apart as possible)
Hydrogen has 1 electron in its outer shell, and in fact only 1 electron in total.

The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
no it only has 1 electron in the outer shell
Bromine has 7 electrons in its outer shell and needs to gain one electron to have a full outer shell and become an ion. It will gain this electron from an atom that has one electron in its outer shell such as Lithium or Sodium.
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most shell.
There is one electron on cobalts outer shell.
The element with chemical symbol As, is Arsenic. Arsenic in part of the Group 15 family of elements along with Nitrogen, Phosphorus, Antimony and Bismuth. Arsenic has 33 electrons in a standard atom, with 4 electron shells and 5 electrons in the outer shell.
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
I think it is that there is only 1 electron in its outer shell.
manganese have 2 electrons in their outer most shell
