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 as potassium, such as sodium and lithium, would react similarly due to their similar outer electron configurations. These elements are all alkali metals and exhibit similar reactivity characteristics, such as forming ionic compounds easily and reacting violently with water.
Well, darling, elements in a group have the same number of valence electrons because they are all too lazy to go out and make new friends. They prefer to stick together and share the same electron configuration, making them behave similarly in chemical reactions. It's like a group of friends who all have the same favorite hangout spot - they just can't be bothered to venture out on their own.
Group 1 elements have an oxidation number of +1.
All of the elements in group 17/VIIA, known as the halogens, will react the same as chlorine, a member of this group. All halogen atoms have 7 valence electrons, so they will form ionic bonds or covalent bonds to get 8 valence electrons.
Barium and calcium are elements that exhibit similar chemical properties to strontium due to their position in the same group (group 2) of the periodic table. They all have similar reactivity when forming compounds with elements like oxygen and chlorine.
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.
Elements in the same group as potassium, such as sodium and lithium, would react similarly due to their similar outer electron configurations. These elements are all alkali metals and exhibit similar reactivity characteristics, such as forming ionic compounds easily and reacting violently with water.
the elements all behave differently an elements behaviors are what happens when they are reacted upon
Of what group??

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.
Group 1 elements have an oxidation number of +1.
All elements in a group have same chemical properties. They have same number of valence electrons.
All of the elements in group 17/VIIA, known as the halogens, will react the same as chlorine, a member of this group. All halogen atoms have 7 valence electrons, so they will form ionic bonds or covalent bonds to get 8 valence electrons.
All elements in the groups (excluding transition metals) have the same number of electrons as the group number.
All elements in the same A group will have the same number of valence electrons.
