cava bio 204 s1.d11 2.01 Chemistry Review

QuestionAnswer
Chemistry is the study of [...]. Chemistry is the study of matter.
Matter is everything in the universe that takes up space and has [...]. Matter is everything in the universe that takes up space and has mass.
Mass is whatever gives things [...]... we can't really define it much better than than. It's just one of those fundamental aspects of the universe that we just have to accept Mass is whatever gives things weight... we can't really define it much better than than. It's just one of those fundamental aspects of the universe that we just have to accept
Matter exists in many different forms. One of the most fundamental kinds of matter is an element . An element is, as you will soon see, a substance that is made of only one kind of [...]. Matter exists in many different forms. One of the most fundamental kinds of matter is an element . An element is, as you will soon see, a substance that is made of only one kind of atom.
*An element's properties are determined by the number of [...] in it's nucleus *An element's properties are determined by the number of protons in it's nucleus
Of the approximately 115 known elements, 92 occur naturally on earth. Of these, however, very few exist in pure form. In fact, most elements in nature are bound up with other elements in complex chemical [-s]. Of the approximately 115 known elements, 92 occur naturally on earth. Of these, however, very few exist in pure form. In fact, most elements in nature are bound up with other elements in complex chemical compounds.
Only four elements make up more than 96 percent of the mass of all living things: 1. [...] 2. Hydrogen 3. Oxygen 4. Nitrogen In particular, [...] plays a central role. Only four elements make up more than 96 percent of the mass of all living things: 1. Carbon 2. Hydrogen 3. Oxygen 4. Nitrogen In particular, carbon plays a central role.

If you could take any element—carbon, for example—and divide it again and again until you found its smallest part, what would that smallest part be? An [...] If you could take any element—carbon, for example—and divide it again and again until you found its smallest part, what would that smallest part be? An atom
[...] are the basic unit of matter. Atoms are the basic unit of matter.
Atoms are made of three sub-atomic particles: 1. [...] 2. Neutrons 3. Electrons Atoms are made of three sub-atomic particles: 1. Protons 2. Neutrons 3. Electrons
Atoms are made of three sub-atomic particles: 1. Protons 2. [...] 3. Electrons Atoms are made of three sub-atomic particles: 1. Protons 2. Neutrons 3. Electrons

[-s] are routinely added to or taken away from atoms. Electrons are routinely added to or taken away from atoms.
Because electrons have a charge, adding electrons to or taking them away from an atom will change the overall [...] of the atom. Because electrons have a charge, adding electrons to or taking them away from an atom will change the overall charge of the atom.
Ordinarily, the only way to change the charge of an atom is to add or take away [...] from it. Ordinarily, the only way to change the charge of an atom is to add or take away electrons from it.
Subtracting a negative is like adding a [...]. Subtracting a negative is like adding a positive.
Subtracting a negative charge (taking away an electron) [-es] the overall charge of the atom. Subtracting a negative charge (taking away an electron) increases the overall charge of the atom.
Adding a negative charge (by adding an electron) [-es] the overall charge of the atom. Adding a negative charge (by adding an electron) decreases the overall charge of the atom.
By definition, all [...] have no charge; they are neutral. This means they have an equal number of protons and electrons. By definition, all atoms have no charge; they are neutral. This means they have an equal number of protons and electrons.
The number of [-s] has absolutely no effect on the overall charge of an atom. The number of neutrons has absolutely no effect on the overall charge of an atom.
By definition all atoms have no charge; if they do have a charge, we call them '[-s]'; not atoms. By definition all atoms have no charge; if they do have a charge, we call them 'ions'; not atoms.
If you want to decrease the charge of an atom, [...] an electron. If you want to decrease the charge of an atom, add an electron.
If you want to increase the charge of an atom, [...] an electron. If you want to increase the charge of an atom, take away an electron.
If an atom starts with a charge of 0 and ends up as an ion with a charge of -1, the charge has [-ed]. If an atom starts with a charge of 0 and ends up as an ion with a charge of -1, the charge has decreased.
If an atom starts with a charge of 0 and ends up as an ion with a charge of +1, the charge has [-ed]. If an atom starts with a charge of 0 and ends up as an ion with a charge of +1, the charge has increased.
If an atom starts with a charge of 0 and ends up as an ion with a charge of -1, it must have [...] an electron. If an atom starts with a charge of 0 and ends up as an ion with a charge of -1, it must have gained an electron.
If an atom starts with a charge of 0 and ends up as an ion with a charge of +1, it must have [...] an electron. If an atom starts with a charge of 0 and ends up as an ion with a charge of +1, it must have lost an electron.
All atoms of the same element must have the same number of [...] in their nucleus. All atoms of the same element must have the same number of protons in their nucleus.

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.
