TermDefinition
atomic mass the mass of an atom, number of protons +neutrons
atomic number number of protons in the nucleus of an atom
Bohr model is a system consisting of a small, dense nucleus surrounded by orbiting electrons—similar to the structure of the Solar System, but with attraction provided by electrostatic forces in place of gravity
electron cloud electron cloud is the region of negative charge surrounding an atomic nucleus that is associated with an atomic orbital.
atoms smallest particle of an element, made of protons, neutrons and electrons
electrons negatively charged subatomic particle that orbits the nucleus of an atom
neutrons a subatomic particle of the nucleus of an atom without a charge that contributes to the atom’s mass-neutral
Nuclear Atomic Model–Rutherford model nuclear model of the atom consists of a small and dense positively charged interior surrounded by a cloud of electrons.
Neucleus positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass.
neucles positively-charged center of an atom that usually contains protons and neutrons.
Planetary Atomic model According to the Bohr model, often referred to as a planetary model, the electrons encircle the nucleus of the atom in specific allowable paths called orbits
Plum Pudding Model Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup.”
Protons positively charged subatomic particles of the nucleus of an atom that contribute to the mass of an atom.
Solid Sphere Atomic Model proposed by John Dalton in 1803. It states that all objects are made of particles called atoms and that they are solid spheres that cannot be divided further into smaller particles.
Structure the arrangement of and relations between the parts or element
sphere a round solid figure
Valence election electrons that located in the outermost electron shell of an atom

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.
