Study Slideshow

Which particles are found in the nucleus?

protons and neutrons

5

Which particles are found in the cloud that surrounds the nucleus?

electrons

5

What is the charge of a proton?

+1

5

What is the charge of a neutron?

0 (neutral)

5

What is the charge of an electron?

-1

5

How is the number of protons for an atom determined?

Look at the atomic number on the periodic table.

10

How is mass number for an atom determined?

number of protons + number of neutrons OR atomic number + number of neutrons

10

What is an isotope?

Atoms of the same element with different masses.

10

What is an ion?

A charged atom.

10

How many electrons can fit into the following energy levels (shells): 1, 2, 3?

1- two electrons 2- eight electrons 3- eight electrons

15

Draw a Bohr model for an atom of Na-23.

See instructor drawing. (11 protons, 12 neutrons, 11 electrons, 3 electron shells-2 electrons in shell 1, 8 electrons in shell 2, and 2 electrons in shell 3)

25

Which isotope is represented by the Bohr model in the picture. Give the symbol and mass number for the isotope.

Mg-24

20

What is the most common isotope for the following atom. Explain how you know.

Na-23; The average atomic mass is 22.9, which would round to 23. Sodium is most commonly found with a mass of 23.
