Dot Diagrams and Bonding

Front

What do covalent compounds do?

Back

Covalent compounds share electrons.

Front

Which element could be represented by this dot diagram? (O)

Back

Oxygen (O) is represented by the dot diagram.

Front

What elements generally make an ionic bond?

Back

Ionic bonds typically form between a metal and a nonmetal.

Front

What happens when an atom gains an electron?

Back

The atom gains a negative charge.

Front

What does ionic bonding involve?

Back

Ionic bonding involves the transfer of electrons.

Front

What is a dot diagram?

Back

A dot diagram is a visual representation of the valence electrons of an atom.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What charge does an atom have if it loses an electron?

Back

If an atom loses an electron, it has a positive charge.

Front

What is a valence electron?

Back

A valence electron is an electron in the outermost shell of an atom that can participate in chemical bonding.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.
