QuestionAnswer
Atoms All things are made up of atoms
Parts of an atom Nucleus( protons and neutrons)
Protons Positive charge
Neutrons No Charge
Opposites attract + attracts – and vice versa
Electron Negative charge
Electron Cloud area where electrons are found
Mass Electron’s mass is smaller the protons and neutrons
Volume The electron cloud makes up most of the volume
Overall charge Neutral
Three Subatomic Particles Protons, neutrons, and electrons
Element Substance that cannot be broken down into simpler substances
# of protons The number of protons determines what kind of element it is
# of elements Over 100 elements and about 90 are found in nature
Smallest unit of an element An atom is the smallest unit of an element
Bonding atoms Sharing or joining electrons
Molecules Group of two or more atoms held together by a very strong chemical bond. Two of the same atoms can join together to form a molecule
Compounds Pure substance made by two or more different elements that are chemically joined. Compounds can only be separated by chemical reactions
Properties of a molecule Properties of compounds can be very different than the elements used to create them.
Identifying Compounds, molecules, and elements Compounds, molecules, and elements are represented by chemical formulas
Periodic Table of elements Presents and organizes information about elements
How the periodic table is organized Elements with similar properties are grouped closer together
Atomic # The atomic number tells how many protons and electrons are in that element
Atomic Mass Measured in AMU, Protons + neutrons
Boxes in the Periodic Table Each box is a model of the atom it stands for
Period The horizontal rows in the periodic table, Periods are numbered 1-7
Groups The vertical columns in the periodic table, Groups numbered 1-18 elements in the same group have the same electrons in the outer layer
Metals More than 75% of the periodic is metals, Metals are located to the left of the dark step like line on the periodic table, They are usually shiny malleable ductile and solid at room temp.
Nonmetals Nonmetals are usually gasses at room temp, solid nonmetals are usually the opposite of metals.
Metalloids Have the same characteristics as metals and nonmetals, They are semi-conductors
Alkali Metals The elements in group 1 of the periodic table, they are most reactive metals, their atoms have one electron in their outer level, metals
Alkaline-earth metals The eements in group two of the periodic table, they are reactive but not as reactive as alkali metals, their atoms have two electrons in the outer level, metals
Transistion Metals The elements in group 3-12, they have 1 or 2 electrons in the outer level, they are less reactive than alkaline-earth metals, metals
Boron Group They are group 13 on the periodic table, they are reactive, there are 3 electrons in the outer level, one metalloid and 4 metals
Carbon Group Group 14 on the periodic table, reactivity varies between the elements, there are 4 electrons in the outer level, one nonmetal two mettaloids and 2 metals
Nitrogen Group Group 15 on the periodic table reactivity varies among the elements, there are 5 electrons in the outer level, Two nonmetals two metalloids and ont metal
Oxygen Group Group 16 on the periodic table, they are reactive, has 6 electrons in the outer level, Three nonmetals one metalloid and one metal
Halogens Group 17 on the periodic table, they are very reactive, 7 electrons in the outer level, nonmetals
Noble Gases Group 18 on the periodic table, They are unreactive, 8 electrons in the outer level except for heliu it has 2, nonmeals
Hydrogen Hydrogen is above group 1 on the periodic table, it is reactive, there is 1 electron in the outer level

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.
