Atomic Structure and Isotopes

Flashcards about atomic structure and isotopes.

What is the relationship between the number of electrons and protons in a neutral atom?

In a neutral atom, the number of electrons is equal to the number of protons.

What are the number of protons, neutrons, and electrons in Neon (Ne)?

Neon (Ne) has 10 protons, 10 neutrons, and 10 electrons.

What are the number of protons, neutrons, and electrons in Calcium (Ca)?

Calcium (Ca) has 20 protons, 20 neutrons, and 20 electrons.

What are the number of protons, neutrons, and electrons in Copper (Cu)?

Copper (Cu) has 29 protons, 35 neutrons, and 29 electrons.

What are the number of protons, neutrons, and electrons in Iron (Fe)?

Iron (Fe) has 26 protons, 30 neutrons, and 26 electrons.

What are the number of protons, neutrons, and electrons in Hydrogen (H)?

Hydrogen (H) has 1 proton, 0 neutrons, and 1 electron.

What are isotopes?

Atoms with the same number of protons but a different number of neutrons.

Give an example of isotopes of Carbon.

Carbon-12 (12C), Carbon-13 (13C), and Carbon-14 (14C) all have 6 protons but different numbers of neutrons (6, 7, and 8, respectively).

Give an example of isotopes of Hydrogen.

Protium (1H) , Deuterium (2H), and Tritium (3H) all have 1 proton but different numbers of neutrons (0, 1, and 2, respectively).

How do isotopes differ in terms of atomic number and mass number?

Isotopes have the same atomic number but a different mass number.
