What is the naming convention for covalent compounds?

• Covalent compounds are named using prefixes to indicate the number of atoms, followed by the name of the first element and the modified name of the second element ending in '-ide'.

• Covalent compounds are named by using the atomic number of the elements involved.

• Covalent compounds are named based on the mass of the elements and their position in the periodic table.

• Covalent compounds are named using the first element's name followed by the second element's name without any modifications.

Define ionic compound.

• An ionic compound is formed when atoms transfer electrons, resulting in positively and negatively charged ions that attract each other.

• An ionic compound is a type of molecule that shares electrons equally between atoms.

• An ionic compound consists of two or more nonmetals bonded together by covalent bonds.

• An ionic compound is formed when atoms lose or gain protons, resulting in charged particles.
