What is a covalent compound?

Back

A covalent compound is a chemical compound formed by the sharing of electrons between atoms, typically nonmetals. An example is water (H2O).

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions to form two new compounds. An example is the reaction between sodium sulfate and barium chloride.

What determines the position of an element in the periodic table?

Back

The position of an element in the periodic table is determined by the number of valence electrons it has.

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.

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products.
