Do molecular compounds have ions?
Molecular Compounds Many compounds do not contain ions but instead consist solely of discrete, neutral molecules. These molecular compounds (covalent compounds) result when atoms share, rather than transfer (gain or lose), electrons.
What is the net charge of molecular compounds?
zero
All molecules and ionic compounds have a net charge of zero.
What does molecular compound have?
All compounds are either molecular or ionic. A molecular compound consists of molecules whose formula represents the actual number of atoms bonded together in the molecule. The atoms are joined to give a definite shape which is defined by the angles between the bonds and by the bond lengths.
Do molecular compounds have to be neutral?
Molecular compounds are electrically neutral. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other.
Can molecular compounds conduct electricity?
Since molecular compounds are composed of neutral molecules, their electrical conductivity is generally quite poor, whether in the solid or liquid state. When molten, however, it can conduct electricity because its ions are able to move freely through the liquid (Figure 6.2.
Do atoms have a charge?
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral.
Why do molecules have a charge?
The difference between the number of electrons and protons in an atom determines how strong the charge is, and what that atom can bond with. Atoms with a positive charge will be attracted to negatively charged atoms to form a molecule.
Do all compounds have a neutral charge?
In every ionic compound, the total number of positive charges of the cations equals the total number of negative charges of the anions. Thus, ionic compounds are electrically neutral overall, even though they contain positive and negative ions.
What are the properties of a 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 |
Why do molecular compounds do not conduct electricity?
Molecular compounds don’t dissociate into ions and so don’t conduct electricity in solution.
What is the charge of a compound?
Do compounds have a charge? Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.)
Can a compound have both a positive and a negative charge?
A compound, by definition, has an overall net charge of zero. You can put a compound in a bottle. If every molecule had a charge, positive or negative, then every molecule would repel every other molecule and … BOOM! There are some compounds, called zwitterions, that have both positive and negative charges within the same molecule.
Can you put a compound in a bottle with a charge?
You can put a compound in a bottle. If every molecule had a charge, positive or negative, then every molecule would repel every other molecule. There are some compounds, called zwitterions, that have both positive and negative charges within the same molecule. So there is a localized charge.
Why are compounds classified as ionic or molecular?
Compounds are classified as ionic or molecular (covalent) on the basis of the bonds present in them. When an element composed of atoms that readily lose electrons (a metal) reacts with an element composed of atoms that readily gain electrons (a nonmetal), a transfer of electrons usually occurs, producing ions.
