WebGenerally speaking, the energy of an electron in an atom is greater for greater values of n. This number, n, is referred to as the principal quantum number. The principal quantum number defines the location of the energy level. It is essentially the same concept as the n in the Bohr atom description. WebOct 13, 2016 · Despite all this, Bohr’s is probably still the model of the atom you’re most familiar with, since it’s often the one first introduced during high school or secondary school chemistry courses. It still has its uses too; it’s quite handy for explaining chemical bonding and the reactivity of some groups of elements at a simple level.

WebOct 17, 2024 · According to the Bohr model, higher energy orbits are located (closer to/further from) the atomic nucleus. This makes sense since negative electrons are (attracted to/repelled from) the positive protons in the nucleus, meaning it must take energy to move the electrons (away from/towards) the nucleus of the atom.
