The group numbers represent the number of valence electrons. 1 has 1, 2 has 2. Then, skipping over transition metals, 13 has 3, 14 has 4, etc.

Which number tells you the number of valence 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.


What is the number of valence electrons for group 2 elements?

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).


What is the difference of number of valence electrons and periodic table group number?

Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.

How do you determine the number of valence electrons in an atom?

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.


How do you determine the number of valence electrons in an element?

To determine the number of valence electrons in an element, you look at the group number on the periodic table. The group number tells you how many valence electrons an element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.


How to determine the number of valence electrons in an atom?

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).


Which group contains least number of valence electrons?

Group 1 with one valence electrons


How many valence are in chlourine?

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.
