Two valence electrons
all the elemants have valence electrons the last number of the elecotrons is the elemets valence electrons
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
Krypton has 8 valence electrons, as it is in Group 18 (Noble Gases) of the periodic table.
As,Arsenic belongs to nitrogen family in periodic table so it has 5 valence electrons.
Strontium has 2 valence electrons because it is part of the Alkaline Earth Metals or Group 2 of the periodic table which all have 2 valence electrons
I want answer
Valence electrons
The valence electrons of gallium (Ga) are located in the p-block of the periodic table. Gallium is in Group 13, which means it has 3 valence electrons in its outermost shell.
The d block of the periodic table contains 10 valence electrons.
its in column two on the periodic table, so therefor it has two valence electrons .
Argon has 8 valence electrons, as it is in group 18 (noble gases) on the periodic table.
all the elemants have valence electrons the last number of the elecotrons is the elemets valence electrons
To determine the number of valence electrons, you look at the group number of an element on the periodic table.
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
As is present in group-15. It has 5 valence electrons.
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.
