Lewis Structure/Bonding Practice

Front

What do you do with the total number of valence electrons if your ion is + charged?

Back

Subtract 1 from the valence number.

Front

What is the first step in drawing Lewis Structures?

Back

Count the number of valence electrons.

Front

Which pair of elements is most likely to form a covalently bonded compound?

Back

S with O.

Front

What is a covalent bond?

Back

A bond formed when two atoms share electrons.

Front

Which of the following is a covalent bond: NaCl, HCl, NH4Cl, ZnCl2?

Back

HCl.

Front

What is the Lewis structure for dinitrogen monoxide?

Back

Structure B.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in bonding.

Front

How do you determine the total number of valence electrons in a molecule?

Back

Add the valence electrons of all atoms in the molecule.

Front

What is the significance of the octet rule in bonding?

Back

Atoms tend to bond in a way that gives them eight valence electrons.

Front

What is a lone pair in a Lewis structure?

Back

A pair of valence electrons that are not shared with another atom.
