WebAnswer: The smallest particle of an element is an atom whereas the smallest particle of a compound is a molecule. The difference between an atom and a molecule is that the atom is the smallest unit of an element, which may or may not exist independently whereas a molecule is formed when two or more similar or different types of atoms are joined … WebThe oxidation state of an atom is a measure of the degree of oxidation of an atom. It is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0. The sum of the oxidation states within a compound or ion must equal the overall charge. Isotopes

WebA proton or neutron. How does the electric charge of a proton compare with the electric charge of an electron? It is equal and opposite. Since atoms are mostly empty space, why don't we fall through a floor we stand on? Electrons in one atom repel the electrons in another. What element has the lightest atoms? WebSolution. Verified by Toppr. Almost all of the mass in an atom is made up of the protons and neutrons in the nucleus. Protons are positively charged and neutrons have no charge on them. Because the nucleus is only made up of protons and neutrons it is positively charged. Was this answer helpful?

WebEvery subshell has a # of orbits s/p/d/f that can each hold 2 electrons each (one has the opposite spin of the other). The first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons. The second shell has 2 subshells: 1 s-orbital and 3 p-orbitals. WebAn atomic radius is half the distance between adjacent atoms of the same element in a molecule.
