WebThe differences in the properties of a solid, liquid, or gas reflect the strengths of the attractive forces between the atoms, molecules, or ions that make up each phase. The phase in which a substance exists depends on the relative extents of its intermolecular forces (IMFs) and the kinetic energies (KE) of its molecules. Web18 aug. 2024 · Ions come in two types. Atoms that gain electrons are known as anions (AN-eye-uns). These have an overall negative charge. The size of that charge depends on how many electrons it gained. For example, an oxygen atom starts with eight protons and eight electrons.

"WebThe iron content of hemoglobin is determined by destroying the hemoglobin molecule and producing small water-soluble ions and molecules. The iron in the aqueous solution is reduced to iron(II) ion and then titrated against potassium permanganate. In the titration, iron(ll) is oxidized to iron(III) and permanganate is reduced to manganese(II) ion. " - Ions and molecules
