Drag the correct electrical charge to each particle of an atom.

Groups:

(a) Proton

,

(b) Neutron

,

(c) Electron

• Positive(+)

• Negative(-)

• Neutral(no charge)

Point to the nucleus of an atom where protons and neutrons are located.

Use the chart below: drag and drop the correct number to each of the followings:

Atomic Number - (a)  

Atomic Mass - (b)  

Protons - (c)  

Neutrons - (d)  

Electrons - (e)  

• 6
• 12
• 4
• 8

Select all statements that are true atoms.

• Atom is the basic unit of all matter.

• Electrons are located in the nucleus.

• Protons and neutrons are located in the nucleus.

• Electrons orbit around the nucleus in energy levels.

In the chart, 1.00794 is the (a)   and 1 is ​ (b)   . Hydrogen has ​ (c)   protons and ​ (d)   electron and ​ (e)   neutron.

• Atomic Mass
• Atomic Number
• 1
• 0
• 2
• 3

A neutral Lithium atom that has 3 electrons, has ​ (a)   protons.

• 1
• 2
• 4
• 3

The atomic number tells the numbers of (a)   or ​ (b)   because atoms are electrical neutral.

• protons
• neutrons
• electrons
• nucleus
