Answer:
protons, neutrons
Explanation:
There are three subatomic particles in all atoms: protons, neutrons and electrons. Of these three, only protons and neutrons are considered to have enough mass to contribute to overall atomic mass of the element.
By making it change probably
Answer:
Repetition
Explanation:
In the world of science, experiments are regularly conducted to test out hypotheses. These experiments are however, not conducted by scientist once to derive a result. They are rather conducted multiple times (repeated) to ascertain the accuracy i.e not as a result of random occurrence. The experiments that undergo multiple trials are said to undergo REPETITION.
This is the case of the scientist in this question, who is conducting an experiment to test what temperature causes the fastest growth rate in sunflower plants. He conducted the experiment multiple times, making it an example of REPETITION.
N.B: Replication is when the experiment is re-conducted by another scientist to see if same result is derived.
it will turn red when placed into an acid and if it is placed into a base, it will turn blue
In the Lewis structure, each single bond drawn between elements contain two electrons. The electron dots represent the lone pairs. These are the electrons that take part in the reaction. To obey the octet rule, the oxygen must have eight electrons around it. The hydrogen is exempted from this rule. Therefore, you have to show two electrons.
