True
Explanation - A hypothesis is given once the question is identified and background research has been done. A hypothesis is validated by performing experiments.
Prior to the experiments being performed, proper planning is done. After the experiment is carried out, the data is noted. Once the data is noted, results are inferred.
If the evidence agrees with the prediction then the hypothesis is being supported and validated. If the result fails to validate the hypothesis then the hypothesis need to be abandoned or modified.
Answer:
Protons and neutrons have approximately the same mass, about 1.67 × 10−24 grams, which scientists define as one atomic mass unit (amu) or one Dalton. Each electron has a negative charge (−1) equal to the positive charge of a proton (+1). Neutrons are uncharged particles found within the nucleus. hope this helps you :)
