The family containing 7 valance electrons is called the Halogens. They are all called (in order of increasing valance electrons): Alkali Metals(1), Alkaline Earth Metals(2), Boron Group(3), Carbon Group(4), Nitrogen Group(5), Oxygen Group/Chalcogens(6), Halogens(7), and Noble Gasses(8/full).

What family of elements has 4 valence electrons?
The family of elements that has 4 valence electrons is the carbon family, which includes carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb). These elements are located in Group 14 of the periodic table.
Atoms that have the same number of valence electrons in their outer shell?
Such atoms belong to a group in the periodic table of elements.
Where are elements with the same number of valence electrons?
All elements in the same group have the same number of valence electrons.
Why do the elements in the vertical columns all have the same chemical properties?
Group 1 have one valence electron. The elements in Group 2 have two. The elements in Group 17 have seven valence electrons, and Group 18 elements have eight. Because the valence electrons within a family are the same, the elements in that group have similar properties.
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
What group of elements has seven valence electrons?
The name of the family is the Halogen family.
What family of elements has 4 valence electrons?
The family of elements that has 4 valence electrons is the carbon family, which includes carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb). These elements are located in Group 14 of the periodic table.
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 do elements in the family have in common?
Elements in the same family (or group) have the number of valence electrons in common. Ex: Family 16 - 6 valence electrons.properties
Atoms that have the same number of valence electrons in their outer shell?
Such atoms belong to a group in the periodic table of elements.
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.
What does the group of A elements tell about valence electrons?
All elements in the same A group will have the same number of valence electrons.
Why do elements in a group have the same number of valence electrons?
The elements in a group, also called a family, have similar properties, one of which is the same number of valence electrons. This accounts for why the elements in a group have similar properties.
Where are elements with the same number of valence electrons?
All elements in the same group have the same number of valence electrons.
What is a family of elements in group 2 with 2 valence electrons?
Alkali-earth metals
How many valence electrons can an atom have?
That depends on the element in question. Atoms can have anywhere from 1 to 8 valence electrons. For the main group elements, Groups 1,2,13-18, the number of valence electrons are the number in the one's place in their group number, as follows: Group 1 Elements: 1 valence electron Group 2 Elements: 2 valence electrons Group 13 Elements: 3 valence electrons Group 14 Elements: 4 valence electrons Group 15 Elements: 5 valence electrons Group 16 Elements: 6 valence electrons Group 17 Elements: 7 valence electrons Group 18 Elements: 8 valence electrons The transition metals, Groups 3 - 12, are more complicated because they are adding d electrons, some of which behave like valence electrons, and many transition metals can have different numbers of valence electrons. For example manganese can have anywhere from 2 to 7 valence electrons.
