phosphate is an ion but all the bonds internally are covalent bonds. phosphate can combine ionically as in Na₃PO₄¯³, or it can combine covalently, as in H₃PO₄¯³. “PO4” isn’t a compound, it is the phosphate ion, and has an oxidation state of -3.

Sodium phosphate (Na3PO4), also known as sodium phosphate or NA3PO4, belongs to the class of inorganic compounds known as alkali metal phosphates. These are inorganic compounds in which the largest oxoanion is phosphate, and in which the heaviest atom not in an oxoanion is an alkali metal.

A compound containing carbon atoms. The elements in Na2O are a metal and a nonmetal, which form ionic bonds. Because sodium is a metal and we recognize the formula for the phosphate ion (see Table 3.1 “Some Polyatomic Ions”), we know that this compound is ionic. Therefore, the atoms form covalent bonds.

PH3 is a covalent polar compound. Phosphorous is bonded to three hydrogen atoms and has a lone pair of electrons.

Phosphine is an example of a polar molecule with non-polar bonds. Since hydrogen and phosphorus are equal in electronegativity, meaning that they attract the shared pairs of electrons the same amount, the bonding electrons are shared equally making the covalent bonds non-polar.

Sodium Phosphate is an ionic compound formed by two ions, Sodium Na+ and Phosphate PO−34 . In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take three +1 sodium ions to balance the one -3 phosphate ion.

By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals.

(c ) In NaOH,Na+ and OH- ions are bonded together by ionic bond while in OH-ion, oxygen and hydrogen atoms are bonded together by convalent bond Na+[O-H]-.

B) NH4Cl : NH4CL contains both an iconic and covalent bond. NH4Cl is made up of ammonium (NH4+) and Chlorine ion. The ammonium ion is polyatomic, which means it forms ionic salts.

NH4Cl is an acidic salt, a single entity of it consist of three covalent bonds and coordinate bond with hydrogen atoms, these leads to a positive charge on the nitrogen atom, which attracts the negative chloride ion (Cl-) forming ionic bond, The molecule can be visulized as composed of a complex ion NH4+ attracts Cl- …

Expert Answers For the first part of the question, NH4CL contains both an iconic and covalent bond. The ammonium ion is polyatomic, which means it forms ionic salts. Therefore whatever bonds it makes are ionic. That said however, the bond between N and H is covalent because both N and H are non-metals.

Ammonium chloride has both covalent & ionic bond is simply because the bond that exist between ammonia is a covalent bond and the bond that exist between hydrochloride is an ionic bond so if both reacted together we are going to have both covalent and ionic bond because the hydrogen atom in the compound hydrochloride …

In ethanol, C2H5OH (1), there are covalent bonds, hydrogen bonds and van der Waals’ forces.

Another example of ionic bonding takes place between magnesium (Mg) and oxygen (O) to form magnesium oxide (MgO). Since oxygen has a higher electronegativity, it attracts the two valence electrons from the magnesium atom and these electrons are transferred from the magnesium atom to the oxygen atom.

There is a strong electrostatic force of attraction between these oppositely charged ions – this is called an ionic bond. The slideshow shows ionic bonds being formed in sodium chloride, magnesium oxide and calcium chloride.

Atoms that share electrons in a chemical bond have covalent bonds. An oxygen molecule (O2) is a good example of a molecule with a covalent bond. Ionic bonds occur when electrons are donated from one atom to another. Table salt (NaCl) is a common example of a compound with an ionic bond.
