Atoms of which element have the greatest tendency to gain electrons?

2 answers:

Fluorine.

Because:- Atoms want to become stable, for an atom to become stable, they need 8 valence electrons. Since Fluorine has 7 valence electrons, it only needs one more electron to become stable and have an octet. An octet is when an atom/element has 8 valence electrons. Since Fluorine will need to gain an electron, it will have a negative charge, and become an anion.

Answer:

A) 3.17 g of Zn

Explanation:

Let's consider the reduction of Zn(II) that occurs in an electrolysis bath.

Zn⁺²(aq) + 2e⁻ → Zn(s)

We can establish the following relations:

1 min = 60 s
1 A = 1 C/s
The charge of 1 mole of electrons is 96,468 C (Faraday's constant).
When 2 moles of electrons circulate, 1 mole of Zn is deposited.
The molar mass of Zn is 65.38 g/mol

The mass of Zn deposited under these conditions is:

$24min \times \frac{60s}{1min} \times \frac{6.5C}{s} \times \frac{1mol\ e^{-} }{96,468C} \times \frac{1molZn}{2mol\ e^{-}} \times \frac{65.38g}{1molZn} = 3.17 g$
