Unit 3 review

atoms to bonding

QuestionAnswer
What part of an atom has a positive charge? proton
What part of an atom has no charge? neutron
What part of an atom has a negative charge? electron
What does the atomic number tell us? number of protons in the nucleus
What does the atomic mass tell us? the total number of protons and neutrons, in the nucleus of an atom, combined
In a neutral atom, the number of protons is equal to the number of... electrons
What is the atomic mass unit (AMU) of a proton? 1
What is the atomic mass unit (AMU) of an electron? 1/1800
What is the atomic mass unit (AMU) of a neutron? 1
How can you find the number of neutrons in an element? atomic mass - atomic number
What is the building block of all matter? atoms
An atom with a charge is called an... ion
An atom more electrons is an ion with what type of electrical charge? negative
An atom more protons is an ion with what type of electrical charge? positive
How many electrons can fit into an atom's first energy level? 2
How many electrons can fit into an atom's second energy level? 8
How many electrons can fit into an atom's third energy level? 18
When bonding, how many electrons does each element want in it's outer energy level? 8
The nucleus of an atom has what charge? positive
What is the smallest particle in an atom? the electron
The Periodic Table is arranged by increasing... atomic number
Is water (H20) a compound or an element? compound (two or more elements are CHEMICALLY combined)
Is oxygen (O) a compound or an element? an element (made of 1 KIND of atom)
If Lithium (Li) has an atomic number of 3 and an atomic mass of 7, how many electrons does it have? 3 (atomic # = # of protons and electrons in a NEUTRAL element)
If Lithium (Li) has an atomic number of 3 and an atomic mass of 7, how many neutrons does it have? 4 (atomic mass - atomic # = neutrons)
Why are atoms electrically neutral? # of protons = # of electrons
Are all three parts of an atom the same size? no (protons and neutrons have a mass of 1, electrons have a mass of 1/1800 because they are too small to count)
Why is CO2 a compound? Two or more elements are CHEMICALLY combined.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
