What else can I help you with?
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?
One thin that is true about valence electrons is that they are electrons associated with an atom and participate in forming chemical bond. They can also release or absorb energy in the form of photons.
