Ionic Compounds

In simplest words

A metal and non-metal will form an ionic compound NO MATTER WHAT​

Some text here about the topic of discussion

IONIC COMPOUNDS

In more complex words

Elements with LARGE electronegative differences will form ionic compounds​

Electronegativity for dummies

Electronegativity

​The amount of valence electrons in an element

(Ability of an atom of an element to attract electrons)​

Poll

Sodium is a non-metal with a valency of 1, therefore it must be:

• Very electronegativty

• Not very electronegative

COVALENT COMPOUNDS

In simple words

Covalent compounds occur between two or more non-metals. Since they're small. They will have low melting points and boiling points

COVALENT COMPOUNDS

Another way of saying

Covalent compounds occur between elements of similar electronegativity

COVALENT MOLECULAR

What is it?​

Covalent MOLECULES are singular units. Therefore, the formula will represent exactly what is present.​

COVALENT MOLECULAR

What is it?​

Covalent LATTICES/NETWORKS are HUGE AF. Therefore, the formula will represent the ratio of elements [empirical formula].​
