Elements with 7 electrons in their outermost energy levels are most likely halogens. This is group 17 (or 7A) on the periodic table, and they include the common and highly reactive elements fluorine (F), chlorine (Cl), bromine (Br), and iodine (I).

∙ 12y agoThis would be helium and the other "noble gases"(neon, argon, krypton, xenon, radon) that have filled outer electron shells. This makes them less likely to chemically react with other elements. The noble gases are the rightmost column in the Periodic Table (IUPAC Group 18).

Which elements is the carbon family have 4 valence electrons?
All of the members of the carbon family have 4 valence electrons.
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.
How many valence electrons in the nean family?
There are 8 valence electrons in the noble gases, the family of elements furthest to the right on the periodic table.
Do a family of elements share the same number of valence electrons?
Yes they do. Groups/Families tell the number of valence electrons (the number of electrons in the outermost energy level).
Why do elements as a family or group share similar properties?
Because they have the same number of valence electrons and need the same number of electrons to fill their valence shells
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
Which elements is the carbon family have 4 valence electrons?
All of the members of the carbon family have 4 valence electrons.
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.
Elements in a group or family have similar properties?
Because groups/families determine how many valence electrons the element will have. Therefore, all the elements in a group/family have the same number of valence electrons Chemimal and Physical.
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
How many valence electrons in the nean family?
There are 8 valence electrons in the noble gases, the family of elements furthest to the right on the periodic table.
What group of elements has seven valence electrons?
The name of the family is the Halogen family.
Do a family of elements share the same number of valence electrons?
Yes they do. Groups/Families tell the number of valence electrons (the number of electrons in the outermost energy level).
How many valence electrons do the nitrogen family have?
Five valence electrons. They all exhibit different oxidation numbers too!!!!
Why do elements as a family or group share similar properties?
Because they have the same number of valence electrons and need the same number of electrons to fill their valence shells
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 highly reactive family of elements with 7 valence electrons.?
halogen
