Activity #1- Introduction to Covalent Bonding

Open

. Scroll down to the heading “Covalent Bonding.”

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?

4. How does the hydrogen atom “pick up” another electron?

5. What compound does hydrogen form?

6. How do hydrogen atoms make a covalent bond?
