What is covalent bonding?

Back

Covalent bonding is the type of chemical bond that occurs between two nonmetals, where they share pairs of electrons.

Front

Why are noble gases unreactive?

Back

Noble gases are unreactive because they all have a full valence shell, which makes them stable and less likely to form bonds.

Front

What type of reaction is represented by the formula C_xH_y + O_2 -> CO_2 + H_2O?

Back

This reaction is a combustion reaction, where a hydrocarbon reacts with oxygen to produce carbon dioxide and water.

Front

What type of reaction is represented by the formula AB -> A + B?

Back

This reaction is a decomposition reaction, where a compound breaks down into its individual elements or simpler compounds.

Front

What type of bonds form between two metals?

Back

Bonds that form between two metals are called metallic bonds.

Front

What is the definition of ionic bonding?

Back

Ionic bonding is the electrostatic attraction between positively and negatively charged ions, typically formed between metals and nonmetals.

Front

What is a combination reaction?

Back

A combination reaction is a type of chemical reaction where two or more substances combine to form a single product.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a chemical reaction where one element replaces another element in a compound.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a chemical reaction where the anions and cations of two different compounds exchange places, forming two new compounds.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to greater stability.
