Here’s something else you can do to illustrate the connection between weight (or mass) and density.
Thorium metal is silvery and tarnishes black when exposed to air, forming the dioxide. Scandium is a silvery-white metallic d-block element, it has historically been sometimes classified as a rare-earth element, together with yttrium and the lanthanides. All rights reserved. All of the alkali metals have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge â a cation, which combines with anions to form salts. Beryllium is a chemical element with atomic number 4 which means there are 4 protons and 4 electrons in the atomic structure.
The chemical symbol for Palladium is Pd. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atomâthe Na+ cation. 312 g p q ‘ ’ ¸ ¹ !
