Ionic Bonds

Two or more atoms bonded together is a....

• molecule

• element

• atom

• bond

Answer explanation

Two or more atoms bonded together form a molecule. An element consists of only one type of atom, while an atom is the basic unit of matter. A bond refers to the attraction between atoms, not the combination itself.

In an Ionic Bond Valence Electrons are what?

• gained or lost

• created

• destroyed

• shared

Answer explanation

In an ionic bond, atoms gain or lose valence electrons to achieve a stable electron configuration. This transfer of electrons leads to the formation of charged ions, making 'gained or lost' the correct choice.

How many valence electrons does an atom need to become stable?

• 8

• 6

• 4

• 2

Answer explanation

An atom needs 8 valence electrons to achieve stability, following the octet rule. This rule states that atoms are most stable when they have a full outer shell of 8 electrons, which is why 8 is the correct answer.

Is Sodium Na the Metal or the Nonmetal in the Ionic Bond? How do you know

• Sodium gains and electron

• Metal

• Non-Metal

• Sodium loses an electron

Answer explanation

Sodium (Na) is a metal because it loses an electron to form a positive ion (Na+). This behavior is characteristic of metals, which typically lose electrons in ionic bonds.

Ionic Bonds occur between what two types of atoms?

• Metals and Non-Metals

• Metals and Metals

• No-Metals and Non-Metals

• Unkown

Answer explanation

Ionic bonds form between metals and non-metals. Metals lose electrons to become positively charged ions, while non-metals gain electrons to become negatively charged ions, resulting in an electrostatic attraction.

Positively charged Atoms are called?

• cations

• anions

Answer explanation

Positively charged atoms are known as cations. They form when an atom loses one or more electrons, resulting in a net positive charge. In contrast, negatively charged atoms are called anions.

Negatively charged atoms are called?

• anions

• cations

Answer explanation

Negatively charged atoms are called anions. This is because anions are formed when atoms gain electrons, resulting in a net negative charge, while cations are positively charged due to the loss of electrons.

Is Fluorine F the cation or the anion in the Ionic Bond? how do you know?

• Fluorine is gaining an electron

• anion

• cation

• Fluorine is loosing an electron

Answer explanation

Fluorine gains an electron to achieve a full outer shell, resulting in a negative charge. This makes it an anion, as cations are positively charged and formed by losing electrons.

An atom that GAINS 1 electron will have what charge?

• -1

• +1

• -2

• +2

Answer explanation

When an atom gains 1 electron, it acquires a negative charge because electrons carry a negative charge. Therefore, the atom will have a charge of -1.

An atom loses 2 electrons, its charge becomes what

• -1

• -2

• +2

• +1

Answer explanation

When an atom loses 2 electrons, it loses negative charge, resulting in a net positive charge. Therefore, the charge becomes +2.
