<span>The answer is A. Copper and silver are two examples of atoms that will form a metallic bond. Pure metals in solid state form nets similar to crystals, but they are not ionic. The electrons of the valence shell are shared by all the atoms. The electrons can move freely in what is called a "sea of electrons" which is what confere metals the property of conducting electricity.</span>
Answer:
The correct answer is "two".
Explanation:
The main bondings that has an effect in a Lewis structure in NO2Cl are the double bondings occurring between the Oxygen atoms and the Nitrogen atom. Since the NO2Cl compound has two oxygen atoms attached to the nitrogen atom, two equivalent lewis structures will be necessary to describe it. I attached an example of two equivalent Lewis structure corresponding to a NO2 molecule.
Aluminum, Carbon, Cobalt, Copper, Zinc, Tantalum
Electrons have electric charge of -1 and the number of electrons in an atom is equal to the number of protons. ... Heavier atoms tend to have more neutrons than protons, but the number of electrons in an atom is always equal to the number of protons. So an atom as a whole is electrically neutral.
