The nucleus of an atom located at the center of the atom contains nearly all of the atoms mass. This has a positive charge because of the protons inside it. There are also neutrons with zero charge. Electrons are orbiting outside the atom. The answer to this problem is d. contains nearly all of the atoms volume.

Answer: d. contains nearly all of the atoms volume.

Explanation:

An atom is the smallest entity of a substance which consists of three subatomic particles called as neutrons, protons and electrons.

The most of the mass of the atom is concentrated in the centre of an atom and is called as nucleus. Protons and neutrons are collectively called as nucleons as they are present in the nucleus and contribute to the mass of the nucleus. Nucleus is very dense as it occupies very less space and most of the space in the atom is empty.

Protons carry positive charge and neutrons does not carry any charge. Thus the nucleus is positively charged.

Electrons carry negative charge and revolve around the nucleus in fixed energy paths called as orbitals.

Which of the following compounds contains the Lead (II) ion? PbO PbCl4 Pb2O Pb2S

KATRIN_1 [288]

PbO Let's look at each of the 4 compounds and see what's needed. PbO. * Oxygen has a valance shell that's missing 2 electrons and wants to get those 2 elections. Lead donates them, so you have a Lead (II) ions. This is a correct choice. PbCl4 * Chlorine wants to grab 1 electron to fill it's valance shell and Lead donates that election. However, there's 4 chlorine atoms and every one of them wants and electron, and lead is donating all 4 of the desired electrons making the Lead (IV) ion. So this is a bad choice. Pb2O * Oxygen still wants 2 electrons and gets them from the lead. But there's 2 lead atoms and each of them donates 1 election making for 2 Lead(I) ions. So this too is a bad choice. Pb2S * Sulfur is in the same column of the periodic table as oxygen and if this compound were to exist would have similar properties as Pb2O and would have Lead(I) ions. So this is a bad choice.
