Ions and Drawing Ions

Question 1

What are ions?

Answer 1

An ion is a charged particle(atom). Ions can either be positively charged(+) or negatively charged(-). This charge is due to a:

• Loss of electrons(the atom becomes a positive (+) ion
• Gain of electrons(the atom becomes a negative (-) ion.

Question 2

How do ions form?

Answer 2

Ions form when atoms join to form compounds. Atoms like to form a Stable Octet in their outer orbital when becoming an ion.

Question 3

How do atoms make Stable Octets?

Answer 3

• Giving away 1, 2, or 3 electrons to another atom.

- Accepting 1, 2, or 3 electrons from another atom.

Question 4

What are anions?

Answer 4

• An anion is an ion with a negative charge.
• Anions are always non-metals.
• Anions are always formed from atoms that have 5, 6, or 7 valence electrons.
• Anions will form when a non-metal gains electrons.

Question 5

What are cations?

Answer 5

• A cation is an ion with a positive charge.
• Cations are always metal.
• Cations are always formed from atoms that have q, 2 or 3 balance electrons.
• Cations will form when a metal loses electrons.

Question 6

How do you name ions?

Answer 6

Anions: When non-metals become anions the of their name changes to ide. If the anion is a polyatomic ion, name it from the table of polyatomic ions.
Cations: When metal atoms become cations the name remains the same. If a polyatomic ion is a cation, name it from the table of polyatomic ions.

Question 7

How do you draw a positive ion?

Answer 7

Put brackets around the diagram and put down a plus and the number of electrons they gave away.

Question 8

How do you draw negative ions?

Answer 8

Put brackets around the diagram ad put down a negative and the number of electrons they gained.

Answer 12

8

Question 13

What is a stable octet?

Answer 13

An atom with a full valence shell when forming ions.

Question 14

The period number of an element equals____.

Answer 14

the number of energy levels.

Question 15

What is valence energy?

Answer 15

The outer energy level.

Question 16

What are valence electrons?

Answer 16

The electrons on the outer energy level.

Question 17

An ion is a ________ in which the number of protons does not equal the number of ______. Ions have _____ or ______ charges associated with them called ionic charges.

Answer 17

Charged particles, electrons, positive, negative.

Question 18

Atoms can form ions by either _____ or ______ electrons.

Answer 18

Gaining, losing.

Question 19

Metals tend to have 1, 2, or 3 electrons in their outer most energy level. The tend to ______ these electrons to form ____ ions.

Answer 19

Giveaway, cation.

Question 20

The names of ions of metal elements ______________.

Answer 20

do not change.

Question 21

Non-metals tend to have 5, 6, or 7 electrons in their outermost energy level. They tend to _____ electrons to fill the energy level, and therefore form ions with a _______ charge. When non-metals form ions, the name of the ion changed its ending to ____.

Answer 21

Gain, negative, -ide.

Question 22

What kind of arrangement of electrons in the outer energy level does a stable ion have?

Answer 22

It has a full level or an empty level.
