Number of group indicates valence electrons. There are 18 groups.
Uranium is a member of the actinoids family; period 7, block f, no group number.
Elements in the same family (group) on the periodic table have the same number of valence electrons and hence they have similar properties and reactivities.
A family on the periodic table is a group of elements that share similar chemical properties due to their similar electron configurations. Each family is represented by a column on the periodic table, such as the alkali metals in Group 1 or the halogens in Group 17.
A column in the periodic table is called a group or a family. Elements within the same group share similar chemical properties due to having the same number of valence electrons. There are 18 groups in the periodic table.
The group no. of Lithium is 1 and its period number is 2.
Each group/family on the periodic table can determine valence electrons by the last number of the group/family number, like helium. It's a noble gas that has 8 valence electrons because it's on the 18 family/group
The family name for group 17 elements in the periodic table is the Halogens.
Bromine belongs to the halogen family and is in group 17 (group VIIA) of the periodic table.
Gold sits in the transitional metal family on the periodic table, group number 11.
Uranium is a member of the actinoids family; period 7, block f, no group number.
Iron's family number on the periodic table is 8. This means that iron is part of Group 8, also known as the transition metals.
Halogen, group 9, atomic number 17
Yes it is a group is a family remember that when dealing with the periodic table.
Group 13 is boron family
Sulfur is in the group 16 (chalcogens) and period 3 of the periodic table of Mendeleev.
Elements in the same family (group) on the periodic table have the same number of valence electrons and hence they have similar properties and reactivities.
Bromine is in the halogen family or group in the periodic table.
