Protons Identify Elements and Valence Electrons Determine Reactivity

QuestionAnswer
Proton a positively charged subatomic particle of the nucleus of an atom that contributes to the mass of the atoms
Atomic Number the number of protons in the nucleus of a single atom
Electron a negatively charged subatomic particle that orbits the nucleus
Valence Electrons the electrons in the outermost energy level of an atom that determine the chemical properties of an element and influence how an element will react with other substances
Reactivity rate at which a chemical substance tends to undergo a chemical reaction; significantly influenced by valence electrons
Electron Cloud the area surrounding the nucleus of an atom where the electrons are found
Net Charge the sum of negative and positive charges P+E= Charge
What does APE stand for? Atomic Number = Protons = Electrons
What does MAN stand for? Mass - Atomic Number = Neutrons
P + N = Mass
P + E = Charge
Chemical Properties are determined by ___________________. Valence Electrons
Reactivity of an element is determined by ____________________. 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 tap the card to flip it. If you knew the answer, tap the green Know box. Otherwise, tap the red Don't know box.

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

If you've accidentally put the card in the wrong box, just tap 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.
