Formulas of Substances by Valency

The valency of an element refers to its combining power or the number of electrons it can gain, lose, or share to form chemical bonds. Here are the formulas of the substances you mentioned, along with the valencies of the elements involved:

1. Potassium Oxide (KO): - Potassium (K) has a valency of 1+. - Oxygen (O) has a valency of 2-. - Therefore, the formula for Potassium Oxide is KO [[1]].

2. Magnesium Chloride (MgCl2): - Magnesium (Mg) has a valency of 2+. - Chlorine (Cl) has a valency of 1-. - Therefore, the formula for Magnesium Chloride is MgCl2 [[2]].

3. Iron(II) Oxide (FeO): - Iron (Fe) has a valency of 2+. - Oxygen (O) has a valency of 2-. - Therefore, the formula for Iron(II) Oxide is FeO [[3]].

4. Aluminum Chloride (AlCl3): - Aluminum (Al) has a valency of 3+. - Chlorine (Cl) has a valency of 1-. - Therefore, the formula for Aluminum Chloride is AlCl3 [[4]].

5. Carbon Monoxide (CO): - Carbon (C) has a valency of 4+. - Oxygen (O) has a valency of 2-. - Therefore, the formula for Carbon Monoxide is CO [[5]].

6. Sodium Bromide (NaBr): - Sodium (Na) has a valency of 1+. - Bromine (Br) has a valency of 1-. - Therefore, the formula for Sodium Bromide is NaBr [[6]].

7. Barium Chloride (BaCl2): - Barium (Ba) has a valency of 2+. - Chlorine (Cl) has a valency of 1-. - Therefore, the formula for Barium Chloride is BaCl2 [[7]].

Valency of Elements

The valency of an element determines its ability to form chemical bonds. Here are the valencies of the elements you mentioned:

- Iron (Fe): The valency of iron can vary. In the case of Iron(II) Oxide (FeO), iron has a valency of 2+ [[3]]. - Carbon (C): Carbon has a valency of 4+ [[5]]. - Bromine (Br): Bromine has a valency of 1- [[6]]. - Chlorine (Cl): Chlorine has two common valencies. In the case of Magnesium Chloride (MgCl2) and Barium Chloride (BaCl2), chlorine has a valency of 1-. In the case of Aluminum Chloride (AlCl3), chlorine has a valency of 1- as well [[2]] [[4]] [[7]].

I hope this helps! Let me know if you have any further questions.
