Draw Lewis structures of the ions or molecules whose formulas are given in the answer choices below. Determine whether each of t
hese species follows the octet rule, is octet deficient (central atom works with less than eight electrons in its valence shell), or has an expanded octet (central atom works with more than eight electrons in its valence shell). Pick the choice which is correct. a) The central atom in N2 has an expanded octet. b) The central atom in XeF4 has an expanded octet. c) The central atom in BeH2 has an expanded octet. d) The central atom in BF3 follows the octet rule. e) The central atom in SF4 follows the octet rule.
Metal ore has other elements in it as well. Also sediment and stone might cover the ore. We don't want to have a phone with sediment on it do we? thus these few reasons are why.
The parts of an atom are electrons, usually found in an electron shell around the nucleus of the atom, and protons and neutrons, found in the nucleus of the atom. Typically, electrons are gained or lost in order to obtain charge.
