I have improved the question but even so - it needs clarifying further
Valence electrons are responsible for chemical boding.
Balanced or neutral elements. They are more stable because they have a balanced number of protons and electrons.
Valence electrons are responsible for reacting and bonding with other elements. These are the electrons in the outermost energy level of an atom and determine the atom's ability to form chemical bonds with other atoms.
Electrons are the subatomic particles that govern potential chemical reactions among elements. They are responsible for forming chemical bonds between atoms by either sharing, gaining, or losing electrons.
The electron cloud form the electrically negative part of an atom; electrons are responsible for the chemical activity of elements.
Elements within a group have a similar number of valence electrons. These electrons are responsible for the chemical properties of an element, which is why elements within the same group often have similar chemical behavior.
The number and arrangement of electrons determine how elements react chemically. Elements strive to achieve a stable electron configuration, such as a full outer electron shell, through gaining, losing, or sharing electrons with other elements. This determines an element's reactivity and chemical behavior.
all elements have the same amount of protons and neutrons. when they are not balanced e.g. there is an extra electron, they are no longer atoms they are ions.
In an electrically neutral, there are as many oppositely charged particles as the electrons. Therefore, the net electrical charge come out to be zero.
Electrons are the subatomic particles responsible for most chemical behavior (with the notable exception of nuclear chemistry), specifically the outer or valence electron shells.The valence electrons are responsible mainly. But protons are responsible for nuclear reactions.
Families or _GROUPS_ of elements are similar due to similarities in their number of valence electrons.Answer:
Valence electrons are the electrons that account for many of the chemical and physical properties of elements. These are the electrons in the outermost energy level of an atom and are involved in chemical bonding and reactions. The number of valence electrons determines an element's reactivity and ability to form compounds.
