Why do elements in same group have similar chemical and physical properties?

Why do elements in same group have similar chemical and physical properties?

A vertical column in the periodic table of elements is called group. So, we can say that elements in a group have the same physical and chemical properties because their atoms have the same number of valence electrons or same valence shell electronic configuration.

How the elements in group 2 are similar?

The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals. All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2.

How are element similar to those in the same group on the periodic table?

All the elements in one group have the same number of valence electrons. Since elements in a group have the same number of valence electrons, they behave similarly in chemistry. An example would be the alkali metals (excepting hydrogen. Hydrogen is in this group only because it has one valence electron.

Why do elements in Group 2 have similar chemical properties?

Two different elements are likely to have similar chemical properties when they have the same number of valence electrons. All elements in the second column of the Periodic Table have 2 valence electrons in an s orbital. These elements are known as Group 2A metals or alkaline earth metals.

Why do the Group 2 metals have similar properties?

All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge. Most of the chemistry has been observed only for the first five members of the group; the chemistry of radium is not well established due to its radioactivity.

Why do elements in a group all behave similarly?

The elements in a group often look and behave similarly, because they have the same number of electrons in their outermost shell — the face they show to the world. Group 18 elements, on the far right side of the table, for example, have completely full outer shells and rarely participate in chemical reactions.

Why are group elements called representative elements?

The elements of “s” and “p” blocks except “d” group elements are called as representative elements because Their outer shells are not completely filled with electrons and The elements get the nearest inert gas configuration by losing or gaining or sharing of electrons.They are chemically active.

What do elements in a group have the same number of?

Every element in a group has the same amount of electrons in their outer shell. For Example, all elements in Group 2 – Alkaline Earth Metals have 2 electrons in their outer shell. Elements in the same group also have very similar characteristics such as what they react with etc.

What do elements in Group 1 have in common?

Group one elements share common characteristics. They are all soft, silver metals. Due to their low ionization energy, these metals have low melting points and are highly reactive. The reactivity of this family increases as you move down the table.
