Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
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.
The representative element in period 4 with 3 valence electrons is phosphorus.
Hydrogen has 1 valence electron, whereas helium has 2 valence electrons.
Elements in the same group (or column) of the periodic table share similar chemical properties because they have the same number of valence electrons, which are the electrons involved in chemical bonding. This similarity in electron configuration leads to comparable reactivity and the formation of similar types of compounds. In contrast, elements in a period (or row) have varying numbers of valence electrons, resulting in diverse chemical behaviors and properties.
Families or _GROUPS_ of elements are similar due to similarities in their number of valence electrons.Answer:
Elements within the same period have the their valence electrons in the same principle energy level. For example, those elements in period 2, have their valence electrons in the 2nd energy level.
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
Elements in the same group have similar properties because they have the same number of valence electrons. In contrast, elements in the same period do not necessarily have similar properties, as their chemical behavior is determined by the number of electron shells they have.
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
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.
The representative element in period 4 with 3 valence electrons is phosphorus.
Yes, elements within the same period of the periodic table have the same number of electron shells, which determines their chemical properties. Elements in the same period also have the same number of energy levels and are influenced by similar trends in atomic radius and electronegativity due to the reactivity of their valence electrons.
Hydrogen has 1 valence electron, whereas helium has 2 valence electrons.
Elements in the same group have similar properties because they have the same number of valence electrons. This influences their chemical behavior and reactivity. Elements in the same period have similar atomic size but vary in other properties due to the changing number of electron shells.
Groups are the number of outer shell electrons in the elements and periods are the number of outer shells in the elements. eg. group 4, period 3 is Silicon which means that it has 3 shells where the electrons are stored and in the last shell it has 4 electrons
Elements with similar properties appear at regular intervals in the periodic table because of their similar electron configurations. As you move across a period, the number of electrons in the outer shell increases, leading to similar chemical reactivity. Additionally, elements in the same group have the same number of valence electrons, which influences their properties.
