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 the same number of valence electrons and hence have similar properties.
They have the same number of valence electrons, and valence electrons are what primarily determine an atom's chemical behavior.
Elements of the same group tend to react in similar ways because each group contains elements with similar chemical properties.
All elements in group 7 have the same no. of electrons in their outermost shells... and this no. correspondes to the group no.
All the Group 14 elements has 4 electrons in its outer energy level.
The elements in Group 0 - Inert Gases group are all highly unreactive and so don't combine with other elements.
group 1A
According to Chemists, the elements of sodium and chlorine belong to the same atomic family as well as carbon and lead.
All of the elements in group 1 on the periodic table will behave similarly to sodium.
The core of the configuration is the same for all elements in a group, the outer shell electrons are also arranged similarly.
the elements all behave differently an elements behaviors are what happens when they are reacted upon
The elements in the Periodic Table are arranged so that elements in the same group (column) will exhibit certain similar characteristics with others in that same group, but different periods (rows). So you can predict, with a certain degree of confidence, how a certain element may behave by where it is located on the periodic table, based on what you know about how other elements in the same group behave. This is mainly due to the valence electrons (the outermost electrons) being the same configuration as others in the same group. The valence electrons are a big determining factor as how that element will react with other elements. They do not all behave exactly the same, but similar.
All substances are made of tiny particles called atoms. An element though, contains just one type of atom. So all atoms of the element gold are alike :) hope this helps!
Of what group??
All elements in group 7 have the same no. of electrons in their outermost shells... and this no. correspondes to the group no.
All elements in a group have same chemical properties. They have same number of valence electrons.
Group 1 Elements (elements in the first group [column]) are classed as Alkali Metals. Group 2 Elements (elements in the second group [column]) are classed as Alkaline Earth Metals. All elements not in a representative group are classed as Transition Metals. Group 3 Elements (elements in the third full group [coulumn]) are classed as Earth Metals
Elements in the same group (column) have the same properties. All the elements in group one have similar properties. All the elements in group two have similar properties. And so on...
All the Group 14 elements has 4 electrons in its outer energy level.
All elements in the groups (excluding transition metals) have the same number of electrons as the group number.
