Chemistry Ionic Bonds

 

What ion does Sulfur (S) make?

-2

Why do atoms form bonds with each other?

to get a complete outer shell of electrons

Which of these elements exist as single atoms because they already have a full valence shell (Octet Rule)?

Neon(Ne)

What is a cation

a positive charged ion

Which of the following describes what happens when an atom of Magnesium (Mg) bonds with an atom of Oxygen (O)?

the magnesium loses two electrons to the oxygen

Which is the correct name for the compound below?

Calcium chloride

The green box represents

a space

Which of these elements is most likely to gain electrons when forming bonds?

fluorine (F)

What are the two exceptions to the octet rule?

Hydrogen & Helium

This is an example of a(n)

Ionic Bond

How many valence electrons do most atoms need to be chemically stable (Octet Rule)?

8

The diagram shows

the order of distributing valence electrons and spaces around elements.

What do we call an element that has a charge due to lost or gained electrons.

ION

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

By looking at the Periodic Table and finding its group number.

What types of atoms make ionic bonds with each other?

metal and nonmetal

The difference between a Bohr Model of the atom and a Lewis Dot Diagram of the atom is

the Bohr Model shows all electrons and the Lewis Dot Diagram shows only the valence electrrons.

What is a valence electron?

An electron in outermost energy level.

The electron dot diagram for aluminum is shown.  How does an atom of Aluminum satisfy the Octet Rule?

loses three electrons to a nonmetal

What is an anion?

a negatively charged ion

What ion does Strontium (Sr) form?

+2
