Which of the following is an ionic compound?

Sodium chloride, on the other hand, contains ions; it is an ionic compound. Ionic compounds contain ions and are held together by the attractive forces among the oppositely charged ions. Common salt (sodium chloride) is one of the best-known ionic compounds.

Is Cao an ionic compound?

Calcium oxide/IUPAC ID

Is Al2O3 an ionic compound?

Aluminium oxide (Al2O3) is not an ionic compound. It is a covalent compound.

Is KF ionic compound?

The oppositely charged ions form an electrostatic attraction, which is the ionic bond. The compound potassium fluoride (KF) results, and since the potassium and fluoride ions have equal but opposite charges, the compound is neutral (but not the individual ions in the compound).

What are 3 ionic compounds?

Sodium chloride, potassium phosphate and magnesium sulfate are the three types of ionic compounds. Compounds that are made up of ions are ionic compounds. These ions are atoms that gain electrons or lose them, giving them a positive or negative net charge.

Is ch4 an ionic compound?

Methane/IUPAC ID

Is Cao ionic or covalent?

Is nh3 an ionic compound?

Ammonia/IUPAC ID

Is nal molecular or ionic?

Sodium iodide is a water-soluble ionic compound with a crystal lattice.

What type of bond is h20?

covalent molecule
Water (H2O), like hydrogen fluoride (HF), is a polar covalent molecule. When you look at a diagram of water (see Fig. 3-2), you can see that the two hydrogen atoms are not evenly distributed around the oxygen atom.

Is i2 ionic or covalent?

Iodine is a diatomic molecule that has covalent bonds holding the atoms together. The iodine atom is a non-metal; when two nonmetals combine, they form a covalent molecule or a molecular compound.

Is PH3 ionic or covalent?

Phosphene PH3 is a covalent compound. The P-H bond has more covalent character. This is because the bonds are formed as a result of overlapping between 3p orbital (of phosphorus) and 1s orbital (of hydrogen).

What type of bond is CaO?

Formula and structure: Calcium oxide chemical formula is CaO and its molar mass in 56.0774 g mol1. The molecule is formed by the calcium cation Ca+2 and the oxygen anion O2, which form a ionic bond. The calcium oxide ionic lattice is cubic and similar to NaCl lattice, with an ion surrounded by 6 opposite charge-ion.

Is h2o l an ionic compound?

It is covalent because the bond between hydrogen and oxygen in water is covalent . its mean the bond between Hydrogen and oxygen is actually formed by sharing of electrons and you should know that this kind of bond is called covalent bond.

What bond is CH4?

covalent bonds
Methane, CH4, is a covalent compound with exactly 5 atoms that are linked by covalent bonds. We draw this covalent bonding as a Lewis structure (see diagram). The lines, or sticks, as we say, represent the covalent bonds. There are four bonds from a central carbon (C) linking or bonding it to four hydrogen atoms (H).

What kind of bond is SO2?

Sulfur dioxide (SO2) is a covalent molecule.

As a result of the small variation in electronegativity between the two atoms, electron bonds are shared, producing covalent bonds.

Does h2 have an ionic bond?

Single Bonds

In the formation of a covalent hydrogen molecule, therefore, each hydrogen atom forms a single bond, producing a molecule with the formula H2. A single bond is defined as one covalent bond, or two shared electrons, between two atoms.

What is the name for the following compound fe2o3?

Ferric Oxide (fe2o3)
