They have the same number of electrons on their outer shells
Hope this helped, if it does please recommend me it would be much appreciated
All elements in the groups (excluding transition metals) have the same number of electrons as the group number.
Elements with the same number of valence electrons are found in the same group or column of the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their chemical properties. For example, all elements in group 1 have 1 valence electron.
Yes, elements with similar chemical properties are often found in the same group on the periodic table. This is because elements within the same group have the same number of valence electrons, leading to similar reactivity and chemical properties.
The elements in a group do not have the same number of shells, however, the elements in a horizontal row do have the same number of shells.
Elements in group have same number of valence electrons. They also have same chemical properties.
Elements with the same number of valence electrons are found in the same group or column of the periodic table. For example, all elements in Group 1 (such as lithium, sodium, potassium) have 1 valence electron.
Elements with similar chemical properties are found in the same group on the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their chemical behavior. Elements in the same period have different numbers of electron shells, leading to varying chemical properties.
Elements that have the same number of valence electrons are found in the same group of the periodic table. For example, all elements in Group 1 (e.g. H, Li, Na) have 1 valence electron, while elements in Group 18 (e.g. He, Ne, Ar) have 8 valence electrons. Valence electrons determine an element's chemical properties and reactivity.
Elements in the same group have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
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.
Two elements that belong to the same group are lithium and sodium. Both elements are found in Group 1 of the periodic table, also known as the alkali metals group. They share similar chemical properties due to having the same number of valence electrons.
