Valence is denoted using a positive or negative integer used to represent this binding capacity. For example,common valencesof copper are 1 and 2. Table of Element Valences NumberElementValence 1Hydrogen(-1), +1 2Helium0 3Lithium+1
The crystal structure of harder metals, such as antimony andbismuth, makes it more difficult to press atoms into new positions without breaking. This is because the rows of atoms in the metal don't line-up. In other words, more grain boundaries exist, which are areas where atoms are not ...
