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?

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

An atom with atomic number 6 would have how many protons

cannot be determined

Multiple Choice

How many protons does fluorine have?

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?

Multiple Choice

What is the atomic number of this Carbon atom

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

How many protons are in Beryllium?

Multiple Choice

How many neutrons does oxygen have?

15.99

Doesn't contain any neutrons

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

Multiple Choice

How many neutrons does Argon have in it's nucleus?

39.948

Multiple Choice

How many protons are in Cadmium?

112.411
