Electron cloud

200

What is the center of the atom called? What two subatomic particles are found there?

Atom Math

100

How do you calculate the number of protons, neutrons, and electrons in a neutral atom?

P=atomic number

N=Mass #-Atomic # 

E=Same as protons

200

An atom has a atomic number of 18 and a mass number of 40. What element is it? How many protons, neutrons, and electrons.

Argon (p=18, n=22, e=18)

300

What is zinc's atomic number? What does this tell you?

30 protons

400

Iron has 26 protons and 30 neutrons. What is its mass number? 

Mass number: 56

500

Rhenium has an atomic number of 75 and a mass number of 186. How many protons, neutrons, and electrons does it have?

P=75

N=111

E=75

Isotopes

100

What is an isotope?

Two atoms of same element with same protons and different neutrons

200

Compare and contrast isotopes.

Same: protons, properties, atomic number

Different: mass number, neutron number

300

Calculate the protons, neutrons, and electrons for neutral Carbon-12 and Carbon-13.

Carbon-12 (p=6, n=6, e=6)

Carbon-13 (p=6, n=7, e=6)

400

Calculate the protons, neutrons, and electrons for Strontium-87 and Strontium-88.

Strontium-87 (p=38, n=49, e=38)

Strontium-88 (p=38, n=50, e=38)

500

Create an isotope for the following atom: Zirconium with a mass number of 91. How many protons, neutrons, and electrons would they each have.

Zirconium-91 (p=40, n=51, e=40)

Zirconium-92 (p=40, n=52, e=40)

Ions

100

What is an ion?

positive or negatively charged atom due to the gain or loss of electrons

200

What is a cation?

Positive ion (lost an electron, so has more protons)

300

What is an anion?

Negative ion (gained electrons, so has more electrons)

400

An atom has 19 protons and 18 electrons. What is its charge? What element is it? Is it a cation or anion?

Charge: +1

Element: Potassium (K)

Cation

500

Charge: -3

Element: Nitrogen

Anion
