1.
As opposed to ____________________ bonding in which a complete transfer of electrons
occurs, ____________________ bonding occurs when two or more elements
__________________ electrons. Covalent bonding occurs because the atoms in the compound
have a similar tendency for electrons (generally to _____________________ electrons). This
most commonly occurs when two ____________________ bond together. Because both of the
nonmetals will want to ___________________ electrons, the elements involved will share
electrons in an effort to _______________ their valence shells.
2.
How many valence electrons are in one atom of hydrogen?
3.
How many valence electrons does hydrogen need to have a full first shell?
How does the hydrogen atom “pick up” another electron?
4.
5.
What compound does hydrogen form?
6.
How do hydrogen atoms make a covalent bond?
7.
