Two or more atoms bonded together is a...

Back

molecule

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?

Back

gained or lost

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.

Front

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

Back

8

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.

Front

Ionic Bonds occur between what two types of atoms?

Back

Metals and Non-Metals

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.

Front

Positively charged Atoms are called?

Back

cations

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.

Front

Negatively charged atoms are called?

Back

anions

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.

Front

An atom that GAINS 1 electron will have what charge?

Back

-1

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.

Front

An atom loses 2 electrons, its charge becomes what?

Back

+2

Answer explanation

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

Front

Is this ionic bond drawn correctly?

Back

Yes

Answer explanation

Yes, the ionic bond is drawn correctly, indicating the transfer of electrons between atoms, which is characteristic of ionic bonding. This confirms that the answer choice 'Yes' is accurate.

Front

In the process of ionic bonding, ions come together because

Back

positive and negative ions attract

Answer explanation

In ionic bonding, positive and negative ions attract each other due to their opposite charges. This attraction leads to the formation of ionic compounds, making 'positive and negative ions attract' the correct choice.
