Elements in group 8 all have 8 valence electrons, this is why these elements are in group 8, they are called noble gases, some examples are Argon, Xenon,
Argon has 8 valence electrons, as it is in group 18 (noble gases) on the periodic table.
The number of Valence Electrons of Xenon is 8 because it is in the eighth group on the periodic table
26
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
8 valence electrons- 1s22s2p63s2p6
Argon has 8 valence electrons, as it is in group 18 (noble gases) on the periodic table.
There are 8 valence electrons in the element Neon, as it is in group 18 of the periodic table.
The number of Valence Electrons of Xenon is 8 because it is in the eighth group on the periodic table
Krypton has 8 valence electrons, as it is in Group 18 (Noble Gases) of the periodic table.
26
Neon is in group 8 of the periodic table, so it has 8 valence electrons.
Since krypton is a noble gas in the group number 18, it has 8 valence electrons. Eight is the maximum number of valence electrons.
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
8 valence electrons- 1s22s2p63s2p6
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
Iron (Fe) is in group 8 on the Periodic Table and it does not have 8 valence electrons. Iron has 2 valence electrons in its 4s orbital and 6 valence electrons in its 3d orbital, making a total of 8 valence electrons.
Cl- has 8 valence electrons. This is because chlorine, in its neutral state, has 7 valence electrons (group 17), and the -1 charge of the chloride ion indicates the addition of an extra electron.
