🗑
|
||||
| What is a covalent bond? | when atoms share electrons
🗑
|
||||
| What is an ionic bond? | a bond that is created from the transfer of one or more electrons from one atom over to the next atom
🗑
|
||||
| What is a polyatomic ion bond? | A compound that has both ionic and covalent bonds
🗑
|
||||
| Why are noble gases nonreactive? | They are stable.
🗑
|
||||
| What does the atom need in order for it to be stable? | a full outer shell
🗑
|

🗑
|
||||
| Know how to identify the number of atoms in a compound. | refer to page 47 and 59
🗑
|
||||
| Know how to write formulas | Remember that + means the element wants to give an electron(s) and - means the element wants to take an electron(s)
refer to page 67
🗑
|
||||
| The Halogen is really reactive to what other family? Explain. | The halogen family is reactive with the alkali metals. This is because the Halogen family wants to take an electron and the Alkali metals want to give an electron.
🗑
|
||||
| What is always true about chemical changes? | Something new is being formed by bonds being formed or broken.
🗑
|
||||
| What are clues to a chemical change? | (1) Drastic color change
(2) Gas given off
(3) Precipitate formed
(4) Energy change

| How many electrons can the first shell hold? second shell? third shell? | The first shell can hold 2 electrons, the second shell can hold 8 electrons, and the third shell can hold 8 electrons.
Remember that an element can have more shells, but we are only looking at those that have up to three shells.
