Covalent Bonding Presentation

What two types of atoms make a covalent bond?

• 2 Nonmetals
• 1 Nonmetal and 1 Metal
• 2 Metals
• 2 Noble Gases

How are covalent bonds explained?

• When one atom takes the other atom's electron
• When the atom shares an electron with an another atom
• When the two nucleus merge
• When the neutrons leave the nucleus

In chemical compounds, covalent bonds form when

• the electronegativity difference between two atoms is very large.
• electrons are completely transferred between two metals.
• pairs of electrons are shared between two nonmetal atoms.
• two nonmetal atoms are attracted to each other by opposite charges.

Why do atoms share electrons?

• To attain the electron configuration of a noble gas.
• To become ions and take a charge
• to increase the mass
• it's a nice thing to do.
