Valence electron configuration in group 1A:
ns1
in which n=1, 2, 3, 4, 5, ... etc.
Starting with Hydrogen, H, electron configuration:
1s1
followed by Lithium, Li, electron configuration:
(1s2), 2s1
(non valence electrons in () brackets)
Valence electron configuration in group 7A (halogens): ns2, np5 in which n=2, 3, 4, 5, ... etc. Starting with fluorine, F, electron configuration: (1s2), 2s2 2p5 (non valence electrons in () brackets)
The general electronic configuration of nitrogen group elements is ns2np3, where "n" represents the valence shell. Each element in this group has 5 valence electrons, with 2 in the s orbital and 3 in the p orbital. This configuration gives these elements similar chemical properties, such as the tendency to form covalent bonds.
The valence electron configuration for Group 6A elements is ns^2 np^4. This means that Group 6A elements have 6 valence electrons in their outermost shell.
Elements that have configuration of ns2np5 are members of the Halogen group(Group VIIA). They are, Fluorine, Bromine, Iodine and Astatine.
Elements in group 1 (alkali metals) have 1 valence electron. This single electron is in the outermost energy level of the atom, making these elements very reactive and likely to lose this electron to achieve a stable electron configuration.

valence electrons and electronic configuration.
All elements in group 1 have 1 valence electron.
Elements that have configuration of ns2np5 are members of the Halogen group(Group VIIA). They are, Fluorine, Bromine, Iodine and Astatine.
well I am a teacher and I say that it is elements and compounds
Elements in group 1 (alkali metals) have 1 valence electron. This single electron is in the outermost energy level of the atom, making these elements very reactive and likely to lose this electron to achieve a stable electron configuration.
Atoms of elements in Groups 13-18 have 10 fewer valence electrons than their groups numbers.However , helium atoms have only 2 valence electrons.
All elements in group 16 share similar properties because their valence shells all contain the s2p4 electron configuration.
All elements in group 16 share similar properties because their valence shells all contain the s2p4 electron configuration.
The Elements have a different Total Number of Electrons, but the same number of Valence Electrons.
