How do the properties of ionic and molecular compounds compare?

Ionic compounds usually form hard crystalline solids with high melting points. Covalent molecular compounds, in contrast, consist of discrete molecules held together by weak intermolecular forces and can be gases, liquids, or solids at room temperature and pressure.

What are the properties of ionic and molecular compounds?

Physical Properties of Molecular Compounds
Property Ionic Compounds Molecular Compounds
Physical state at room temperature Solid Gas, liquid, or solid
Water solubility Usually high Variable
Melting and boiling temperatures Generally high Generally low
Electrical conductivity Good when molten or in solution Poor

How do ionic compounds and molecular compounds compare structurally?

Molecular compounds are pure substances formed when atoms are linked together by sharing of electrons while ionic compounds are formed due to the transfer of electrons. 2. Molecular compounds are made due to covalent bonding while ionic compounds are made due to ionic bonding.

How are ionic and molecular compounds similar?

The most obvious similarity is that the result is the same: Both ionic and covalent bonding lead to the creation of stable molecules. The reactions that create ionic and covalent bonds are exothermic because elements bond together to lower their potential energy. … Both ionic and covalent bonds form in fixed quantities.

What properties are the same for ionic and molecular covalent compounds?

PROPERTIES OF IONIC COMPOUNDS
Ionic compounds Covalent compounds
They have high melting points and boiling points. That is, ionic compounds are non-volatile. They have usually low melting points and boiling points. That is, covalent compounds are usually volatile.

What are the differences and similarities between molecular compounds vs molecules?

A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds. All compounds are molecules.

What is the difference between an ionic compound and a molecular compound quizlet?

What is the difference between an ionic compound and a molecular compound? In ionic compounds the atoms (or group of atoms) exist as ions and are held together by electrostatic forces. In molecular compounds the atoms are held together by covalent bonds.

In what ways do the names of ionic compounds and molecular compounds differ?

Ionic: Cation is named first followed by the anion. If it’s an ionic compound with a transition metal, there are more than one possible ion. Molecular – named with the least electronegative ion first + prefixes are given to both ions to indicate number of atoms in each element. The 2nd ion ends in “ide”.

Which statement best summarizes the difference between ionic and molecular compounds?

Which statement best summarizes the difference between ionic and molecular compounds? (A)The key difference between ionic and covalent compounds is the types of elements that compose them, not the way that the atoms bond together.

How does an ionic compound differ from a metal?

Ionic compounds occur between a non-metal and a metal where positive and negative ions occupying alternate positions in a regular lattice. The positive ions are metal ions that have lost electrons and the negative ions are non-metals that have gained electrons. For example, Sodium Chloride (NaCl).
