Electron outer shell tee hee =^-^=
An Ion
Two electrons in the outer shell of radium.
depends on the atom and how many electrons it needs to complete its outer shell. Elements like Oxygen, Florine i.e. the right side of the periodic tableexcludingthe noble gases, these elements want to take an electron off of the metal groups which are generally on the left side of the Periodic Table, the metal elements for example arePotassium, Magnesium etc. The metals want to lose an electron because they are closer to having an full outer shell if they get rid of 1 or two electrons
An atom of Hydrogen (H) has one electron (-1) and one proton (+1), and is uncharged (0). H+ indicates that the Hydrogen atom has lost an election (-1) but still has the proton (+1) and thus has a positive charge (H+). Because it only had one electron to begin with, when H becomes H+ it does not have any electrons left. Therefore, H+ does not have any electrons.
Seven , outer shell electrons or valence electrons increase as you move from left to right on the periodic table not including the transition metals which vary, they start with 1 valence in the alkali earth metals , and finish with 8 valence electrons on the noble gasses (group 18)
In a covalent bond, each atom retains its outer shell of electrons. The atoms share pairs of electrons to achieve a full outer shell, which makes the bond stable.
A lithium atom has one electron on the outer shell. This is because there is 2 electrons maximum on the inner shell, so there is one left over for the outer shell. Hope you understand now xx
An Ion
It would be a non-metal and a halogen. Group 18 or the noble gases, all have 8 electrons in their outer shell. Therefore, the group before it would have seven electrons in the outer shell. This group is made up of all non-metals.
Two electrons in the outer shell of radium.
These electrons are called "outershell electrons" or "valence electrons."
filled with electrons
The number of electrons an atom has in its outer shell determines its reactivity. Atoms tend to gain, lose, or share electrons to achieve a stable electron configuration, usually with a full outer shell of electrons. This process allows atoms to become more stable and less reactive.
