Group 2 elements are all metals, which already tend to lose 2 electrons. A simple way of explaining why group 2 loses two electrons is that atom's are most stable with 8 valence electrons, group 2 has has 2 valence electrons and therefore it is easier to lose 2 rather than gain 6.
Elements of the same group generally share the same number of valence electrons, which are the electrons in the outer energy level only. These are the electrons that participate in a chemical reaction, so elements in the same group behave similarly in chemical reactions, which makes predictions and generalizations possible.
Elements within a group have a similar number of valence electrons. These electrons are responsible for the chemical properties of an element, which is why elements within the same group often have similar chemical behavior.
Elements in the same group behave similarly because they all have the same number of electrons in their outer-most orbits. These electrons are what determines the types of bonds and chemical reactions the atom can undergo.
Elements in the same group have similar chemical properties but not necessarily similar atomic numbers. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical properties.
They have the same number of valence electrons which, in general, gives them similar oxidation numbers and other similar chemical and physical properties. The similarities are most pronounced in the groups at either side of the standard periodic table, and are least pronounced for the transition and rare earth elements.

Elements in group have same number of valence electrons. They also have same chemical properties.
Elements within a group have a similar number of valence electrons. These electrons are responsible for the chemical properties of an element, which is why elements within the same group often have similar chemical behavior.
Because their outer electronic structure is nearly the same, they also have the same amount of valence electrons, so it leads to similar chemical reactions (or similar bonds with other atoms)
Elements in the same group behave similarly because they all have the same number of electrons in their outer-most orbits. These electrons are what determines the types of bonds and chemical reactions the atom can undergo.
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.
Elements in the same group have the same number of valence electrons, which dictates their chemical behavior. Valence electrons are responsible for the way atoms interact with each other in chemical reactions. This similarity in valence electron configuration leads to similar chemical reactivity among group members.

Group 13A elements, also known as boron group, tend to lose three electrons during chemical reactions. This is because they have three valence electrons in their outermost energy level. Losing these electrons allows them to achieve a stable octet configuration and form a +3 charge.
Yes it is. This makes it easy to predict how another element in the same group will react in a chemical reaction. It's done this way on purpose.
Group number describes the number of valence electrons. It helps in estimating chemical properties of that element.For example-group-1 elements have 1 valence electronThe group number of an element is equal to the number of valence electrons. The number of valence electrons is responsible for the chemical properties. So the chemical properties of the element can be determined by the group number.
