Electrostatics

Which subatomic particle has a positive charge?

• proton

• neutron

• electron

• midichlorian

Which subatomic particle has a negative charge?

• proton

• neutron

• electron

• cybertron

Which subatomic particle as no charge, also known as a neutral charge?

• proton

• neutron

• electron

• chakra

What is the net charge:

+ + +

- - - -

• + 1

• -1

• +3

• -4

How to calculate net charge:

• Protons minus valence electrons

• Atomic number - Atomic mass number

• Protons minus Electrons

• Atomic mass number - Atomic number

In a neutral atom, the number of electrons is equal to the number of _______.

• Neutrons
• Orbits
• Protons
• subatomic particles

If two charges repel each other, the two charges must be

• Positive and neutra
• Positive and negative
• positive and neutral
• negative and negative

An object becomes charged when the atoms in the object gain or lose

• electrons
• protons
• neutrons
• all of the above

If you rub a glass rod with a piece of silk, the rod becomes positively charged. This means that

• friction destroyed electrons in the rod.
• the silk has become negatively charged.
• protons have moved to the rod.
• glass attracts more protons.

Objects that have opposite charges

• are attracted to each other, and the force between the objects pulls them together.
• are attracted to each other, and the force between the objects pushes them apart.
• are repelled by each other, and the force between the objects pulls them together.
• are repelled by each other, and the force between the objects pushes them apart.
