Many elements combine with hydrogen(valence = 1) to give
compounds called hydrides.
Use the position of an element in the periodic table to deduce its
valence.
Write formulas for these hydrides without using subscripts,
for example XH3.
If no hydride forms, write "none".
What is the formula of the hydride formed by
bismuth?
What is the formula of the hydride formed by
germanium?

Answer true or false. 1. Atoms that lose electrons to achieve a filled valence shell become cations and form ionic bonds with anions. 2. Ionic bonds tend to form between elements on the left side of the Periodic Table, and covalent bonds tend to form between elements on the right side of the Periodic Table. 3. Electronegativity is a measure of an atom's attraction for the electrons it shares in a chemical bond with another atom. 4. Fluorine, in the...
