Question

1. there is a force of __________ between positively charged ________ and negatively charged ________. a. when particles move ________, they move closer together, and the attractive forces between them are ________. b. when particles move ________, they move farther apart, and the attractive forces between them are __________.

Explanation:

This problem relates to electrostatic forces in Chemistry (a subfield of Natural Science). Positively and negatively charged particles (ions or atoms) have an attractive force. For sub - parts a and b, we use the concept that the strength of the attractive force between charged particles is inversely related to the distance between them (Coulomb's law concept for simple understanding here). When particles move towards each other (decreasing distance), the attractive force increases. When they move away (increasing distance), the attractive force decreases.

Answer:

The main blank: attraction; positively charged: particles (or ions/atoms); negatively charged: particles (or ions/atoms)
a. When particles move \underline{towards each other}, they move closer together, and the attractive forces between them are \underline{stronger}.
b. When particles move \underline{away from each other}, they move farther apart, and the attractive forces between them are \underline{weaker}.
