single valency. last orbit has 7 electrons.
Sodium chloride is composed of sodium (Na) and chlorine (Cl). Sodium has a valency of +1, while chlorine has a valency of -1. In sodium chloride, sodium donates its electron to chlorine, forming an ionic bond with a valency of +1 for sodium and -1 for chlorine.
Copper Chloride
The valency of a chloride ion in a chlorine molecule is -1. Each chloride ion gains one electron to fill its outer shell and achieve a stable electron configuration.
The valency of potassium ion (K+) is +1, zinc ion (Zn2+) is +2, and chloride ion (Cl-) is -1. Valency represents the combining power of an element in a compound, based on its ability to gain, lose, or share electrons.
The correct formula is AlCl3
The valency of the chloride ion (Cl⁻) in barium chloride (BaCl₂) is -1. In this compound, barium (Ba) has a valency of +2, allowing it to bond with two chloride ions to achieve electrical neutrality. Thus, each chloride ion contributes a valency of -1, resulting in the formula BaCl₂.
Symbol: Cl-Valency: -1.
Sodium chloride is composed of sodium (Na) and chlorine (Cl). Sodium has a valency of +1, while chlorine has a valency of -1. In sodium chloride, sodium donates its electron to chlorine, forming an ionic bond with a valency of +1 for sodium and -1 for chlorine.
In calcium chloride (CaCl₂), calcium has a valency of +2, meaning it can form two positive charges. Each chloride ion (Cl) has a valency of -1. To balance the positive charge of one calcium ion, two chloride ions are needed, resulting in the overall formula CaCl₂. Thus, while calcium has a valency of +2, the compound itself doesn't have a valency; instead, it reflects the ratio of the ions involved.
Copper Chloride
The valency of a chloride ion in a chlorine molecule is -1. Each chloride ion gains one electron to fill its outer shell and achieve a stable electron configuration.
The valency of lead (Pb) in PbCl2 is +2, as it forms two chloride ions (Cl-) with a -1 charge each, resulting in a neutral compound. In PbCl4, the valency of lead is +4, as it forms four chloride ions. Therefore, PbCl2 has a lead valency of +2, while PbCl4 has a lead valency of +4.
The valency of potassium ion (K+) is +1, zinc ion (Zn2+) is +2, and chloride ion (Cl-) is -1. Valency represents the combining power of an element in a compound, based on its ability to gain, lose, or share electrons.
we usually use roman numerals in writing names of compounds of transitional elements which have more than one valency . for example we have two compounds of iron chloride , iron(II)chloride and iron(III)chloride depending on the valency of iron in each compound.
Their valency is one. They both belongs to the third period.
AgCl It always has a valency of +1, though it is a transition metal
The correct formula is AlCl3
