PRACTICE: Elements, Compounds and Mixtures

Good morning!

In this Quizizz Lesson, you will review and practice differentiating among:

• proton, neutron and electron

• element, compound and mixture
  

You need to complete both sides of the worksheet and turn it into the sub for a grade.

Thank you and have a fabulous Friday!

​Let's start by identifying the difference among protons, neutrons and electrons.

Directions:

1. Copy the characteristic beside the symbol.

2. Use the symbols to complete the Venn diagram.

Multiple Select

Select the two particles with an electrical charge.

• electron

• neutron

• proton

Multiple Choice

Select the positively charged particle.

• electron

• neutron

• proton

Multiple Choice

Select the particle with a negative charge.

• electron

• neutron

• proton

Multiple Choice

Select the particle that is neutral, does not have a charge.

• electron

• neutron

• proton

Multiple Select

Select the two particles that make up the atomic mass. Each have a mass of 1 amu.

• electron

• neutron

• proton

Multiple Choice

Select the particle that identifies the element, and gives an element its atomic number.

• electron

• neutron

• proton

Multiple Select

Select the two particles that are located in the nucleus.

• electron

• neutron

• proton

Multiple Choice

Select the particle that is located in the electron cloud.

• electron

• neutron

• proton

Multiple Select

Select ALL of the subatomic particles.

• electron

• neutron

• proton

​Check (and correct) your Venn diagram.

​Let's review diagrams representing elements, compounds and mixtures.

Directions:

1. Read the review slides.

2. Pause Quizizz lesson to complete the PRACTICE side of the worksheet.

3. Use the Quizizz questions to check and correct your worksheet.

​What do all of these pictures have in common?

Same atoms throughout....

​They all represent ELEMENTS, and have the same type of atom throughout.

Diagrams of two atoms of the same type bonded together are elements. A real world example is the oxygen (O₂) we breathe.

​​What do all of these pictures have in common?

​​They are all compounds

Compounds are 2 or more different elements chemically connected together.

​​​What do all of these pictures have in common?

​​They are MIXTURES.

​The composition is NOT the same throughout.
