Atoms

What are ATOMS made of?

Atoms are made up of Protons (+) and Neutrons (0) which are both found in the nucleus. Orbiting the Nucleus are the Electrons (-) in the Electron Cloud.

Multiple Choice

Which two types of atomic particles carry an electrical charge?

• protons and electrons
• quarks and neutrons
• neutrons and electrons
• protons and neutrons

Multiple Choice

Which of these is the electron?

• A
• B
• C
• D

Multiple Choice

Particles in an atom that are neutral and have no charge are 

• negatrons 
• electrons 
• neutrons 
• protons 

Multiple Choice

What part of the atom is the arrow pointing to?

• nucleus
• proton
• electron shell
• electron

Multiple Choice

the central region of an atom where its neutrons and protons are is its 

• nucleus 
• electron cloud
• core 
• center 

Protons, Neutrons, and Electrons:

*Protons and Neutrons have a mass of 1AMU.

*Electrons hardly have any mass -> .000525AMU.

Multiple Choice

Most of the mass in an atom is concentrated in the...

• electrons
• nucleus
• protons
• empty space

Multiple Choice

An atom's mass number equals the number of...

• protons plus the number of electrons
• protons plus the number of neutrons
• protons
• neutrons

Atomic # = # of Protons

• The # of protons identifies an atom.

• The Mass of an atom is the sum of all protons and neutrons.

Multiple Choice

• 6
• 12
• 3
• cannot be determined 

Multiple Choice

How many protons does fluorine have?

• 19

• 1

• 9

• 10

Multiple Choice

Use a periodic table to help you determine the element in the image. (Hint: Use the # of protons.)

• boron

• beryllium

• neon

• lithium

Multiple Choice

Use a periodic table to help you determine the element in the image. (Hint: Use the # of protons.)

• lithium

• oxygen

• magnesium

• carbon

Multiple Choice

The number 18 represents the

• Atomic number

• Neutrons

• Element Name

• Element symbol

Multiple Choice

What is the mass number of this Carbon atom?

• 8

• 12

• 6

• 15

Multiple Choice

What is the atomic number of this Carbon atom

• 6

• 8

• 14

• 12

Atomic Mass = P + N

We round the atomic mass to the nearest whole #, 4.

Since we already determined that Helium has 2 protons that means:

4 (mass) = 2 P and(+) ? Neutrons

2 Plus what equals 4?

2!! The amount of Neutrons in a Helium atom is 2.

Multiple Choice

Multiple Choice

What is the formula to solve for the neutron?

• Mass + Atomic Number= Neutrons
• Mass x Atomic Number = Neutrons
• Mass - Atomic Number = Neutrons
• Mass + Number of Protons = Neutron
