There would be two electrons. The electronic configuration would be just 1s2 and this is termed the duplet configuration.
There are 8 electrons in the outer energy level of xenon. Xenon belongs to the noble gas group on the periodic table, which have a full outer energy level with 8 electrons.
Bromine has 7 electrons in its outer energy level, making it one electron short of a full outer shell.
The halogens have 7 electrons in their outer shell desparate to gain the 1 electron to make a full shell of 8 electrons.
A full outer ring of an atom is when it has achieved the stable electron configuration known as the octet rule, where the outermost energy level is filled with 8 electrons (2 electrons for hydrogen and helium). This makes the atom more stable and less reactive.
Alkali earth metals have 2 electrons in their outer energy level. This outer level is known as the valence shell, and having 2 electrons makes these metals highly reactive and likely to form ionic bonds to achieve a full outer shell of 8 electrons.

Bromine has 7 electrons in its outer energy level, making it one electron short of a full outer shell.
Nonmetals almost have a full outer energy level while metals have few electrons in their outer energy level.
The halogens have 7 electrons in their outer shell desparate to gain the 1 electron to make a full shell of 8 electrons.

If an atom has 6 electrons in its outer energy level it will acquire two more electrons two give it a full octet. This will be done through the formation of two chemical bonds or a double bond.
Noble gases are the gases in the rightmost column of the Periodic Table that have a full outer energy level. This is why the noble gases do not react with other elements readily. When an atom has a full outer energy level, it means that it has the maximum number of electrons in these outer shells, making it stable.
because they both want to gain full outer shell. They don't have completed outer shells. Hydrogen has one electron in it's outer shell so it wants to ger rid of that by giving it to oxygen. (oxygen itself needs two electrons to get full outer shell which is 8 electrons, so two hydrogens are needed to complete one oxygen atom) and then water is formed.

If the outer energy level of an atom is already filled with electrons, it is less likely to react because atoms tend to be more stable when their outer energy levels are full. This full outer level signifies that the atom has achieved a more stable electron configuration (usually the octet rule for most elements).
Oxygen has 6 valence electrons. These are in the outer orbit.
