Name the compound written as CuF2?

Answer 1

First, you need to determine the elements in the equation. They are copper and fluorine, respectively.

Next, we determine if the compound is ionic or covalent. Remember that a basic ionic cmpd is a metal bonded to a nonmetal, and a basic covalent compount is non-metal-non-metal. Copper is a metal, so the bond is ionic.

To name an ionic compound, you have the first part (the metal) written regularly, and the second part (in this case a monoatomic non-metal) is written regularly, but the last part is dropped and replaced with "ide". So far, the name of our compound is Copper fluoride.

There is a certain type of metal called a transition metal. These metals, unlike the alkali or alkaline earth metals, have no set charge. Therefore, we must determine copper's charge and indicate it in the name.

Balancing the charges: fluoride has a -1 charge. There are two F ions, making the charge of the non-metals -2. The charge must be balanced to 0, which can be done using thie following equation:

x + -2 = 0 --> add 2 to both sides, the twos cancel on the right, and we get x = 2. Therefore the charge of the copper ion is 2+.

To indicate this in the name, you put the charge in roman numeral form in parenthesis after the metal. The final name is Copper (II) fluoride.

Answer 2

Copper( II ) Flouride

Answer 3

CuF is Copper(I) fluoride

Answer 4

Copper II fluoride.

Answer 5

The name of CuF2 is copper(II) fluoride

Answer 6

It is called Copper(I) fluoride.
