Ions

1) What do we mean by a neutral atom? 2) Use Phosphorus and Sodium and mathematically show how they are neutral.

3) How do atoms of an element achieve a full outer shell of 8 electrons? 4) What will happen to the overall charge of an atom if it gains or loses electrons?

5) Consider Oxygen: How many protons and electrons does a neutral atom of oxygen have? 6) How many valence electrons does oxygen have?

7) Is “O” a M or NM? 8) Will “O” lend or borrow electrons? How many? 9) If you borrow electrons you will have a negative charge. Negative charge is called an anion.

10) Put it all together….Write the symbol of the element with the charge! 11) 12) What does it mean when an ion has an overall negative charge?

13) Consider Aluminum: How many protons and electrons does a neutral atom of aluminum have? 14) How many valence electrons does aluminum have?

15) Is “Al” a M or NM? 16) Will “Al” lend or borrow electrons? How many? 17) If you lend electrons you will have a positive charge. Positive charge is called a cation.

18) Put it all together….Write the symbol of the element with the charge! 19) 20) What does it mean when an ion has an overall positive charge?

21) Consider carbon: How many protons and electrons does a neutral atom of carbon have? 22) How many valence electrons does carbon have?

23) Is “C” a M or NM? 24) Will “C” lend or borrow electrons? How many? 25) If you borrow electrons you will have a negative charge. Negative charge is called an anion.

26) Put it all together….Write the symbol of the element with the charge! 27) 28) What does it mean when an ion has an overall neagtive charge?
