Answer 1

Answer:

1) What are canal rays? Answer: Canal rays are positively charged radiations which led to the discovery of positively charged sub-atomic particle called proton.

2) If an atom contains one electron and one proton, will it carry any charge or not? Solution : An electron is a negatively charged particle, whereas a proton is a positively charged particle. The magnitude of their charges is equal. Therefore, an atom containing one electron and one proton will not carry any charge.

Explanation:

Have a great day

Answer 2

1) Canal rays are positively charged radiations. These rays consist of positively charged particles known as protons. They were discovered by Goldstein in 1886.

2) An electron is a negatively charged particle, whereas a proton is a positively charged particle. The magnitude of their charges is equal. Therefore, an atom containing one electron and one proton will not carry any charge.
