They all have a different electrons
they all have a differnet number of electrons, but all have a charge of 1-
Elements in group 1 have a lower number of electrons with respect to the other elements in the same period.
Such atoms belong to a group in the periodic table of elements.
Elements in the same family have the same number of valence electrons.
You can look at the periodic table of the elements and determine the number of valence electrons in that element. The Alkali metals have one The Alkaline earth metals have two The Transition metals have one to three, it depends The Boron family have three The Carbon family have four The Nitrogen family have five The Oxygen family have six The Halogen family have seven The Noble gases have eight
Group I (alkali metals) and group II (earth-alkali metals)
they all have a differnet number of electrons, but all have a charge of 1-
Elements in the same family are related because of shared properties. For example, all the elements in the noble gas family do not react to anything and are colorless, nonflammable, odorless, and tasteless under normal circumstances.
similar chemical properties and characteristics
Elements in group 1 have a lower number of electrons with respect to the other elements in the same period.
Such atoms belong to a group in the periodic table of elements.
the same number of valence electrons (which is the same number of electrons in the atom's outermost shell)
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).
Elements in the same family have the same number of valence electrons.
Elements in the same family (or group) have the number of valence electrons in common. Ex: Family 16 - 6 valence electrons.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.
