Use the description below to answer the following question: which of the following statements best describes how Atom X and Atom Y are related? Atom X has 9 protons, 10 neutrons, and 9 electrons Atom Y has 9 protons, 9 neutrons, and 9 electron a. X and Y are isotopes of the same element
b. X is an ion, and Y is a neutral atom
c. X and Y are different elements
ch
d. X is the element neon, and Y is the element fluorine

The number of neutrons is obtain through the difference of the mass number and the number of electrons

Explanation:

By looking at the periodic table, you will see that Fluorine has 9 protons.

Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well.

Meanwhile, it's mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.

As for the atomic number, it is obtainable through the periodic table itself.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
