2. Protons
3. Electrons
4. Either answer b or c

3. Isotones will be the same element, just a different version of that element?

1. False
2. True
3. It depends on the atomic mass

4. By removing electrons, one will have performed what process?

1. Ionization
2. Conservation of charge
3. Coulomb’s Law
4. Newton’s Laws of Motion

5. What steps must we use to avoid gaining KE when we start to move a charge?

1. Put the test charge extremely close to the charge in question
2. Make sure to do it as slow as possible
3. Use the Electric force
4. Have a charge distribution that is favorable

Answer 1

1) b - True

For a positive charge, the electric field lines around thd charge point away from the charge.

The direction of electric field is the direction of force exerted on a unit positive charge kept at that point. A positive charge would repel another positive charge, and hence the electric field would point away from the charge.

2) b - Protons

The atomic number of an element is considered as the number of protons in the nucleus.

3) a - False

Isotones are elements with same number of neutrons. Thus isotones are considered as atoms of different elements with same number of neutrons.

4) a - Ionisation

When an electron is removed from a neutral atom, a positively charged ion is formed.
