Atomic Number/Mass

QuestionAnswer
The characteristics of each element depend on the nature of its [...]. The characteristics of each element depend on the nature of its atoms.
an atom has a nucleus that contains [...] and neutrons, and that is surrounded by electrons. an atom has a nucleus that contains protons and neutrons, and that is surrounded by electrons.
the part of the atom that most distinguishes one element from another is the number of [...] in the atoms the part of the atom that most distinguishes one element from another is the number of protons in the atoms
The number of [...] in an atom is that atom's atomic number. The number of protons in an atom is that atom's atomic number.
The number of [...] plus the number of protons in an atom is that atom's mass number. The number of neutrons plus the number of protons in an atom is that atom's mass number.
The atomic number and mass number of an atom tell about the organization of its [...]. The atomic number and mass number of an atom tell about the organization of its nucleus.
The [...] number minus the atomic number gives you the number of neutrons. The mass number minus the atomic number gives you the number of neutrons.
The periodic table gives you the atomic number of each element and its *[...]* atomic mass; the average mass number of its different isotopes. The periodic table gives you the atomic number of each element and its *average* atomic mass; the average mass number of its different isotopes.
Isotopes are versions of an element that have the same [...] number but different [...] numbers. Isotopes are versions of an element that have the same atomic number but different mass numbers.
Isotopes of an element have the same number of [...], but a different numbers of neutrons. Isotopes of an element have the same number of protons, but a different numbers of neutrons.
You can always find out an atom's atomic number by using the [...]. You can always find out an atom's atomic number by using the periodic table.
In the periodic table, the atomic number is never a [...] number, but the average atomic mass usually is. In the periodic table, the atomic number is never a decimal number, but the average atomic mass usually is.
Protons have a [...] charge ([...]), neutrons are neutral in charge (0), and electrons have a negative charge (-1). Protons have a positive charge (+1), neutrons are neutral in charge (0), and electrons have a negative charge (-1).
The electrical balance of an atom is determined only by the numbers of protons and [...]. The electrical balance of an atom is determined only by the numbers of protons and electrons.
An electrically neutral atom has an equal number of [...] and electrons, so the positive and negative charges cancel out. An electrically neutral atom has an equal number of protons and electrons, so the positive and negative charges cancel out.
The net charge of a [...] atom is 0. The net charge of a neutral atom is 0.
If given the number of proton it's also possible to determine the number of [...] in any electrically neutral atom. If given the number of proton it's also possible to determine the number of electrons in any electrically neutral atom.
an atom has a nucleus that contains protons and [...], and that is surrounded by electrons. an atom has a nucleus that contains protons and neutrons, and that is surrounded by electrons.
an atom has a nucleus that contains protons and neutrons, and that is surrounded by [...]. an atom has a nucleus that contains protons and neutrons, and that is surrounded by electrons.
The number of protons in an atom is that atom's atomic [...] The number of protons in an atom is that atom's atomic number.
The number of neutrons plus the number of [...] in an atom is that atom's mass number. The number of neutrons plus the number of protons in an atom is that atom's mass number.
The number of neutrons plus the number of protons in an atom is that atom's [...]. The number of neutrons plus the number of protons in an atom is that atom's mass number.
The mass number minus the [...] number gives you the number of neutrons. The mass number minus the atomic number gives you the number of neutrons.
The mass number minus the atomic number gives you the number of [...]. The mass number minus the atomic number gives you the number of neutrons.
Isotopes of an element have the same number of protons, but a different numbers of [...]. Isotopes of an element have the same number of protons, but a different numbers of neutrons.
Protons have a positive charge (+1), [...] are neutral in charge ([...]), and electrons have a negative charge (-1). Protons have a positive charge (+1), neutrons are neutral in charge (0), and electrons have a negative charge (-1).
Protons have a positive charge (+1), neutrons are neutral in charge (0), and [...] have a negative charge ([...]). Protons have a positive charge (+1), neutrons are neutral in charge (0), and electrons have a negative charge (-1).

An electrically neutral atom has an equal number of protons and electrons, so the positive and negative charges [...]. An electrically neutral atom has an equal number of protons and electrons, so the positive and negative charges cancel out.
The net charge of a neutral atom is [...]. The net charge of a neutral atom is 0.
If given the number of proton it's also possible to determine the number of electrons in any electrically [...] atom. If given the number of proton it's also possible to determine the number of electrons in any electrically neutral 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.
