Which number tells you the number of valence electrons?
The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.
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).
How do you use te periodic table to identify the number of electrons available for bonding?
Valence electrons describe the number of available electrons for bonding. The group number describes outermost electron. The elements in same group has same valence electrons.The number of electrons available for bonding are the valence electrons. In an element, the group number is equal to the number of valence electrons. So the number of electrons available for bonding can be identified by the group number.
Which group contains eight valence electrons?
Group 18 contains eight valence electrons, namely the noble gases.
What does the group number help tell you in columns?
Group number describes the number of valence electrons. It helps in estimating chemical properties of that element.For example-group-1 elements have 1 valence electronThe group number of an element is equal to the number of valence electrons. The number of valence electrons is responsible for the chemical properties. So the chemical properties of the element can be determined by the group number.
Which group contains least number of valence electrons?
Group 1 with one valence electrons

What is the expected number of valence electrons for a group 3 A element?
The expected number of valence electrons for a group 3 A element is 5 number of 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 can you find the number of valence electrons?
the number of valence electrons is the number group on the table its on
What is the different about the valence electrons for all elements in a group?
The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
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.
What does the group number of a element tell about valence electrons?
All elements in the same A group will have the same number of valence electrons.
Which group contains eight valence electrons?
Group 18 contains eight valence electrons, namely the noble gases.
Where are elements with the same number of valence electrons?
All elements in the same group have the same number of valence electrons.
