Answer:

For A: The correct answer is Option E.

For B: The correct answer is Option E.

Explanation:

For A:

Ionic compound is defined as the compound which is formed by complete transfer of electrons from one atom to another atom.

This bond is usually formed between a metal and a non-metal or a metal reacts with a polyatomic ion or a reaction between two polyatomic ions takes place.

For the given options:

Option A: $RbNO_3$

This compound is formed by the combination of $Rb^+\text{ and }NO_3^-$ ions. Rubidium is a metal and nitrate is a polyatomic ion

Hence, it is an ionic compound.

Option B: $Na_2SO_4$

This compound is formed by the combination of $Na^+\text{ and }SO_4^{2-}$ ions. Sodium is a metal and sulfate is a polyatomic ion

Hence, it is an ionic compound.

Option C: $MgCl_2$

This compound is formed by the combination of $Mg^{2+}\text{ and }Cl^-$ ions. Magnesium is a metal and chlorine is a non-metal

Hence, it is an ionic compound.

Option D: $NaI$

This compound is formed by the combination of $Na^+\text{ and }I^-$ ions. Sodium is a metal and iodine is a non-metal

Hence, it is an ionic compound.

Thus, the correct answer is Option E.

For B:

Covalent compound is defined as the compound which is formed when sharing of electrons takes place between the atoms. This is usually formed between two non-metals.

Option A: $SO_2$

This compound is formed by the combination of sulfur and oxygen atoms. Both are non-metals.

Hence, it is a covalent compound.

Option B: $C_2H_2O$

This compound is formed by the combination of carbon, hydrogen and oxygen atoms. All are non-metals.

Hence, it is a covalent compound.

Option C: $NO_2$

This compound is formed by the combination of nitrogen and oxygen atoms. Both are non-metals.

Hence, it is a covalent compound.

Option D: $SiO_2$

This compound is formed by the combination of silicon and oxygen atoms. Both are non-metals.

Hence, it is a covalent compound.

Thus, the correct answer is Option E.

Answer:

An atom is made of up subatomic particles called protons, neutrons and electrons. The center of an atom is called the nucleus and is where the protons and neutrons are held while electrons orbit the nucleus in orbital shells. A electron has a negative charge, a proton has a positive charge, and a neutron has no charge (neutral).

The atomic number of a atom is the total amount of the atom's protons. In a neutral atom (Not an ion), the amount of electrons is the same as the protons. Therefore, the atomic number also tells the amount of electrons in the atom.

A ion is a negatively or positively charged particle due to the giving or taking of electrons with one or more atoms (Called an ionic bond). An atom that gives away electrons becomes positively charge because that atom now has more protons than neutrons. An atom that takes an electron becomes negatively charge because that atom now has more electrons than protons.

Atomic Mass is the sum of an atom proton and neutrons. To determine how many neutron an atom has, subtract the atomic mass from the atomic number. Electrons do not play a part in atomic mass as their mass is 1/1,836 of a proton's mass.

A isotope is two or more forms of the same element that contain equal amounts of protons but different amount of neutrons.

If an organism is heterozygous, it has one copy of two different alleles. If an organism is homozygous, it has two copies of the same allele.
