Generally speaking, the metals give away electrons during a reaction. Not all metals are equally reactive, however. The metals of group 1 (the alkali metals) all have 1 valence electron. This 1 electron is given away very easily, making this group the most reactive of all the metals. They are so reactive, in fact, that these elements do not exist by themselves; only in compounds.
The chemical bond formula group. To find this out you have to do: Mass divided by volume, that gives you the density. Then divide that answer in half(2) to get the chemical bond formula group.
The groups of elements that easily gains one valence electrons is group 7A. This is what is commonly known as halogens.
If you are thinking about electricity, that would be conductors.
Group 7 (now known as Group 17)...also known as the halogens.
groups of seventy.
Group 17 - the halogens.
Group 7, halogens
-- JT
group 16
It becomes an ion.
Ion. Any atom that loses or gains an electron becomes an ion.
The same number of valence electrons as xenon.
If one electron is gained, then it has a charge of -1.
Group-17 in the periodic table gains electron most readily. The elements in this group require only one electron to complete its octet.
An Electron
It becomes an ion.
A negatively charged "ion".
Ion. Any atom that loses or gains an electron becomes an ion.
Ion. Any atom that loses or gains an electron becomes an ion.
When an atom gains or looses a valence electron it becomes a charged particle called an ion
Ion.
Ion.
The same number of valence electrons as xenon.
because they can each get a full valence shell by combining electrons, and have no need to share with other elements. (NA gives away one electron, giving it eight in its valence shell, and CL gains that electron, which also makes its valence shell eight).
Elements that are in the same group of the periodic table have the same number of electrons in their outer energy level. In the case of lithium and sodium, they each have one electron in their farthest shell.
