While a neutral atom for scandium would have the same number of electrons as protons, the ion is shown to have a +3 charge. This means it has 3 fewer electrons than the neutral atom or 21 - 3 = 18 electrons. Answer The Sc 3+ ion contains 21 protons and 18 electrons.
WebMar 6, 2024 · Because electrons are negatively charged, when an element is in its neutral state, it will have the same number of protons as electrons.

For the following atoms, predict the number of electrons that would be gained or lost to form an … WebWhy form chemical bonds? The basic answer is that atoms are trying to reach the most stable (lowest-energy) state that they can. Many atoms become stable when their valence shell is filled with electrons or when they satisfy the octet rule (by having eight valence electrons). If atoms don’t have this arrangement, they’ll “want” to reach it by gaining, …
