Atoms often form ions by losing or gaining enough electrons to end up with a full outer shell. How many electrons are in a full outer shell for most atoms? Don't know? How about Googling full outer shell?
There are 7 valence electrons in elements of group-17. They are called halogens.
Nitrogen has five valence electrons and needs three more to achieve a full valence shell of eight electrons, in accordance with the octet rule. By gaining three electrons, nitrogen can complete its outer shell, typically forming covalent bonds with other elements to achieve this stable configuration.
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
A total of 7 valence electrons. If I remember correctly, the number of valence electrons of all group A elements are designated by their group number. Chlorine is in group VIIA, hence 7 valence electrons.
From one - e.g. Copper - to eight - e.g. Nickel.
How many valence electrons do transition elements have?
Nitrogen will have two valence electrons forming a triagonal pyramid structure.
Halogen family members, or elements in group 17, have 7 valence electrons.
There are 7 valence electrons in elements of group-17. They are called halogens.

Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.
Calcium has 2 valence electrons, like all Group 2 elements.
there are 36 electrons in a valence shell. -cmoney
Group 16 (VIB or VIA) elements have six valence electrons.
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
Group 3 elements have 3 valence electrons. These elements include boron, aluminum, gallium, indium, and thallium.
Group 16 (VIB or VIA) elements have six valence electrons.
