Question

Which statement is true about alpha particles?

1) Alpha particles have a positive charge.
2) Alpha particles have a negative charge.
3) Alpha particles have no charge.
4) Alpha particles are smaller than beta particles.

Answer 1

The correct statement about alpha particles is that they have a positive charge, specifically a 2+ charge, due to their composition of two protons and two neutrons.

Step-by-step explanation:

The statement that is true about alpha particles is that they have a positive charge. Alpha particles consist of two protons and two neutrons, equivalent to a helium nucleus, and carry a charge of 2+.

Due to their positive charge, they will be attracted towards a negative charge in an electric field. In comparison, beta particles are electrons with only one negative charge and are smaller than alpha particles, which are larger due to their composition.
