What is an ionic bond?

Back

An ionic bond is the attraction between oppositely charged atoms, typically formed when one atom donates an electron to another.

Why do chemical reactions occur?

Back

Chemical reactions occur to make atoms more stable by allowing them to achieve a full outer shell of electrons.

How many electrons can fit in the 1st valence shell?

Back

The 1st valence shell can hold a maximum of 2 electrons.

Front

How many electrons can fit in the 2nd valence shell?

Back

The 2nd valence shell can hold a maximum of 8 electrons.

What is the atomic structure of carbon?

Back

An atom of carbon has 6 protons, 6 electrons, and typically 6 neutrons, but can have variations in the number of neutrons.

What is the charge of a neutral atom?

Back

A neutral atom has no overall charge, meaning the number of protons equals the number of electrons.

What is the significance of valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom and are important for chemical bonding and reactions.

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving stability.

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

How do you determine the number of neutrons in an atom?

Back

The number of neutrons can be determined by subtracting the atomic number (number of protons) from the atomic mass.
