Hi! :")
Hypothesis: Recommended explanation of the case taken as a starting point for further investigation.
Theory: The explanation obtained by the scientific method and which has a solid foundation that is tested and approved through observation and experiments.
Difference: Theory is not predicted in any field The accuracy of the same big bang theory is unknown.. However, the hypothesis is still under investigation and proof.
Good Luck ;)

A. Climate- given condition of earth’s atmosphere in any specific point
Answer: By definition, if the atomic number =
7
, then there are 7 protons, 7 electrons, and 8 neutrons!
Explanation:
The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles. Why? Because matter is electrically neutral, and positive and negative particles must be equal.
Electrons have negligible mass; the mass number depends on the number of protons contained within the nucleus, PLUS the number of neutrons. Given that we have 15 N
, there must be 8 neutrons contained within the nucleus. does this help?
Choice #1 & Choice#4 I believe
