Periodic Table

Vocabulary for Matter and Elements

TermDefinition
Matter Anything that has mass and takes up space.
Mass The material that matter is made up of.
Volume How much room/volume matter takes up.
Density D=m/v The amount of material/stuff matter takes up within a specific space.
Atom The smallest part of an element, the building blocks to all matter.
Electron Negatively charged particle of an atom that circles the nucleus and has an attractive force that bonds other atoms to create everything.
Proton Positively charged particle of an atom found inside the nucleus.
Neutron Particle of an atom with a neutral charge, no charge inside the nucleus.
Periodic Table A large grid that identifies and classifies all of the elements by their chemical and physical properties.
Element The simplest substance that can be created but can not be broken down/makes up all of the universe.
Periods Rows that tell how many energy levels(orbitals)each element has for the electrons to move around it.
Groups or Family Columns that show how many valence electrons an element has/The number of electrons that is aloud to move on the outer shell.
Valence Electrons The electrons that move on the outer shell.
Atomic Number How many protons an element has inside the nucleus/usually the same amount of neutrons and electrons.
Atomic Mass the measurement of the mass for an elements atoms.
Chemical Property Change into a whole new substance,change of color.
Physical Property The state of matter it's in,the size,shape,color,and texture.
Ionic Bond The actin when elements either lose or gain an electron during bonding.
Covalent Bond When elements share electrons during bonding.
Reaction Elements bond together through the attractive force of electrons creating some type of reaction and change.
Compound/Molecule Two or more elements combine together in a specific ratio/pattern creating a whole, new and different substance.
Mixture Two or or more elements physicaly combine, keeping there original properties.
Nobel Gases All of the elements in group #18-these are most stable becausee all have 8 electrons in there outer shell.
Halogens All of the elements in group #17-they are very reactive, bonding easily with elements in group #1 because they have seven valence electrons.
Alkali Metals All of the elements in group #1--They are vvery reactive because they only have one valence electron.
Metalloids Elements between matals and non-metals that can react either way, they have 3--7 valence electrons.

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.
