Which group of elements 7 valence electrons?
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
Does a group of elements share the same number of valence electrons?
Yes In Groups 1A through 8A
How Are Groups On A Periodic Table Numbered?
Groups on the periodic table are numbered from 1 to 18, with the group number corresponding to the number of valence electrons in the elements of that group. Group 1 elements have 1 valence electron, group 2 elements have 2 valence electrons, and so on. Groups 1, 2, and 13-18 are known as the main group elements.
What is the rule on finding valence electrons for groups 13-18?
The number of Valence electrons in the groups 3 to 12 is variable, and depends on the element that it is being bonded with.For example:If Iron (Fe) is going to form a compound with Sodium (Na), the Fe will act as though it has 7 valence electrons (i.e. it is willing two accept the one Na Valence electron).
How do you determine the number of valence electrons if you know the group no of elements?
valence electrons are electrons at the outermost shell as we all know, group in PE can be determined by looking at the valence electron thus if it is in group 1..then the valence electron is 1
What sublevels are the valence electrons in groups 13-18?
13-18 is p
Which group of elements 7 valence electrons?
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
Does a group of elements share the same number of valence electrons?
Yes In Groups 1A through 8A
What is the valence electron for group 3?
The number of valence electrons in groups 3 through 7 is the same as the group number, and for group 12 the number of valence electrons is 2. For groups 8 through 11, the number of valence electrons must be determined individually from individual electronic configurations.
How can you find out an element in the representative groups number of valence electrons?
To find the number of valence electrons for an element in the representative groups (Group 1, 2, 13-18), you can look at the group number. Elements in Group 1 have 1 valence electron, Group 2 have 2 valence electrons, Group 13 have 3 valence electrons, and so on up to Group 18 which have 8 valence electrons. The group number gives you the number of valence electrons for elements in the representative groups.
How do you figure out how many valence electrons an atom has based on its location on the periodic table?
For groups 1-2 the number of valence electrons is equal to the number of the group.For groups 13-18 the number of valence electrons is equal to the number of the group, but with numbering starting up from 3 (13), 4 (14) , etc. (transition metals excluded).

What are the valence electron of an atom?
The valence electrons are found on the valence shell, the outermost shell of an atom. By using the periodic table and the group numbers, one can find the number of valence electrons for elements in groups (vertical columns) 1-2 and 13-18. For the 1st 2 groups (1 and 2), the group number tells the number of valence electrons for elements which belong in that group Elements in the 1st group have 1 valence electron and elements in the 2nd group have 2 valence electrons. For groups 13-18, refer to the tens' value (the teen value that is not the "1" in these cases). Elements in group 13 have 3 valence electrons, elements in group 14 have 4 and so on to the the final group, 18, where electrons have a full octet of valence electrons.
Which group has different numbers of valence electrons?
Noble gases have a full valence shell with 8 electrons, while all other groups typically have fewer valence electrons. Transition metals have varying numbers of valence electrons depending on their position in the periodic table.
How do you find the valence electron for groups one and two?
Group one has one valence electron, and group two has two valence electrons
