The group number in the periodic table tells you the number of valence electrons for main group elements. The group number is the same as the number of valence electrons, except for transition metals.
To determine the number of valence electrons in an atom, look at the group number on the periodic table. The group number indicates the number of valence electrons. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
To determine the number of valence electrons in an element, look at the group number on the periodic table. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, while elements in Group 2 have 2 valence electrons.
The number of valence electrons in an atom can be determined by looking at the group number of the element on the periodic table. The group number indicates the number of valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
To determine the number of valence electrons in an atom, look at the group number on the periodic table. The group number indicates the number of valence electrons. For example, elements in group 1 have 1 valence electron, while elements in group 18 have 8 valence electrons (except for helium, which has 2).
its a valence number which is and above
the number of valence electrons is the number group on the table its on
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
The group number in the periodic table tells you the number of valence electrons for main group elements. The group number is the same as the number of valence electrons, except for transition metals.
Two valence electrons.
It has 4 valence electrons and a valence electron potential of 95.2

To determine the number of valence electrons in an element, look at the group number on the periodic table. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, while elements in Group 2 have 2 valence electrons.
Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.
