Valence Electrons
Number of valence electrons
Chemical elements that are in the same group within the periodic table have the same numbers of electrons in the outermost shell. This gives them similar reactivity.
The chemical elements in a group have similar properties.
Elements with similar properties occur within the groups(columns) on the periodic table.Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
Elements of same group have the same number of valence electrons and hence have similar properties.
Elements within a group always have the same number of valence electrons.
Elements in the same group have similar properties. The groups are made according to the properties of elements. Elements in a group have an equal number of valence electrons.
The elements in the same groups usually do. Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
No. Elements in the same group have same number of valence electrons.
Elements in the same group have similar electronic configurations. For example, all elements in Group 1 contain 1 unpaired electron located in an S orbital. It's the electronic configuration of atoms (and to a lesser degree, their size and charge) which dictate their chemical properties. Nuclear properties, on the other hand are dictated largely by the atoms size and number of protons and neutrons. Chemists, for the most part, aren't interested in these.
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 same number of valence electrons and hence have similar chemical and physical properties.
