Modern atomic theory states that atoms are neutral. how is this neutrality achieved ? a. equal number of neutrons and protons b. equal number of protons and electrons c. more electrons than protons c. more neutrons than electrons

Option (B) is the correct answer.

Explanation:

An atoms consists of protons, neutrons and electrons. Protons are positively charged, neutrons have no charge and electrons are negatively charged.

Also, when an atom is neutral then there are equal number of protons and electrons.

For example, a neutral sodium atom has 11 protons and 11 electrons.

Therefore, we can conclude that modern atomic theory states that atoms are neutral as they have equal number of protons and electrons.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
