Answer:
10: Number of protons always equal number of electron, but that's the case with a neutral atom. ... This implies that it has same number of protons and electrons in it. It means it has same amount of positive and negative charge, which cancel each other, and the atom as a whole becomes electrically neutral.
19: The three stable isotopes of Argon, Argon-36, Argon-38, and Argon-40, would all have 18 protons and 18 electrons if they are all neutral. The three isotopes will have different numbers of neutrons compared to each other (18, 20, and 22 neutrons respectively).
20: This isotope of fluorine has 9 protons, 9 electrons and 10 neutrons.

Answer:
<h2>Cross out unnecessary phrases: Cut out introns.</h2>
Explanation:
The mRNA is a transcript of DNA . Primary mRNA transcript is edited before translation.
Mature mRNA is transcribed into protein, which is the final product of central dogma.
mRNA contains introns and exons , introns are removed by splicing.
the analogy of mRNA editing is Cross out unnecessary phrases: Cut out introns.
