The species that represents an ion is B³+ (option A).
<h3>What is an ion?</h3>
An ion is an atom or group of atoms bearing an electrical charge, such as the sodium and chlorine atoms in a salt solution.
Simply put, an ion is said to be an electrically charged atom. This refers to the difference in the number of protons and electrons in the atom of an element.
According to this question, the species with an electrical charge is B³+, hence, it represents an ion.

Answer:
B) The group the atom is located
C) There needs to be 2 Na atoms and 1O atom to form Na2O
NO2 is a covalent compound
Answer:
Compounds can be broken down into simpler substances by chemical means, but elements cannot. break a compound into simpler substances; oxygen and hydrogen that water contains.
But where is the following?
3.6*10^20 atoms* (1 mol/ (6.02*10^23 atoms))= 6.0*10^(-4) mol.
6.0*10^(-4) mol* (28.1 g/ 1 mol)= 1.7*10^(-2) g.
Note that the units cancel out so you get the answer.
The final answer is 1.7*10^(-2) g Si.
