What is one vanelence electron in the alkalia metlas?
Plaes be meor speific.
What is the element with the first alkalia metal with a completed 3p?
It would be potassium (K). Its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s1.
How do transition metals compare to the reactivity of the alkalia or alkaline earth metals and why?
Transition metals generally have less reactivity than alkali or alkaline earth metals. This is because transition metals have more filled electron shells which provide greater stability, making it harder for them to lose or gain electrons compared to alkali or alkaline earth metals. Transition metals typically form compounds by sharing electrons or by forming complex ions, unlike alkali or alkaline earth metals that readily form simple ionic compounds by losing electrons.
Why elements in Group 1 have a valence of 1?
Elements in Group 1 have a valence of 1 because they have one electron in their outermost energy level, known as the valence shell. This makes them highly reactive as they can easily lose this one electron to form a stable, singly charged cation.
