Answer:

zinc, Zn²⁺, zincate ion

Explanation:

Let us check with all the given examples:

a) Fluorine (F). It is the most electronegative element and thus cannot form positive ion. It will gain electron and form a negative ion (F⁻) known as Fluoride ion.

b) Zinc: it is a metal and give two electrons easily to attain noble gas configuration. Hence it will form Zincate ion (Zn⁺²).

c) Copper,: it is a metal and can form positive ion easily.

It can give either two or one electron to form

Cu⁺²: Cupric ion [More common]

Cu⁺: Cuprous ion

d) Barium : it is alkaline earth metal and will give only two electron to form dipositive ion barium ion (Ba⁺²)

Use the value of the Avogadro constant (6.02 × 1023 mol–1) to calculate the total number of atoms in 7.10 g of chlorine atoms. (
kolbaska11 [484]

The total number of atoms in 7.10g of chlorine is 1.204 × 10²³atoms.

HOW TO CALCULATE NUMBER OF ATOMS:

  • The number of atoms in a substance can be calculated by multiplying the number of moles in that substance by Avogadro's number as follows:

  • no. of atoms = no. of moles × 6.02 × 10²³ mol-¹

  • The number of moles in 7.10g of Cl is calculated as follows:

no. of moles = mass ÷ molar mass

no. of moles = 7.10g ÷ 35.5g/mol

no. of moles = 0.2mol

no of atoms = 0.2mol × 6.02 × 10²³

no. of atoms = 1.204 × 10²³atoms.

  • Therefore, the total number of atoms in 7.10g of chlorine is 1.204 × 10²³atoms.
