Just remember how many electrons can each sublevel hold.

S=2
P=6
D=10

Since we have 10 for atomic number, we can assume we have 10 electrons

1S2
2S2
2P6
The rest have zero because we already have 10 (2+2+6=10)

Write an equation that shows the formation of the chloride ion from a neutral chlorine atom
jeka57 [31]

The gaining of electron by an atom results in the formation of anion shown by the negative charge on the atom whereas lose of electron results in the formation of cation shown by positive charge on the atom. The atom lose or gain electron to complete their octet and get stable in nature.

The chlorine atom will gain an electron and form chloride anion with one negative charge on it. The chloride ion is more stable in nature compared to the chlorine atom due to complete octet of chloride ion by gaining of electron.

Electronic configuration of chlorine atom is:

[Ne]3s^{2}3p^{5}

By gaining of one electron, electronic configuration of chloride ion is:

[Ne]3s^{2}3p^{6}

Thus, the equation that shows the formation of the chloride ion from a neutral chlorine atom is:

Cl+1e^{-}\rightarrow Cl^{-}

What mass of calcium chloride is produced from 5.59 mol of hydrochloric acid
svp [43]

From the mole ratio of the reaction as given in the equation of the reaction, the mass of calcium chloride that can be produced from 5.59 mol of hydrochloric acid is 310.245 g.

<h3>What mass of calcium chloride can be produced from 5.59 mol of hydrochloric acid?</h3>

The mass of calcium chloride that can be produced from 5.59 mol of hydrochloric acid is determined from the equation of the reaction.

The equation of the reaction is given below:

Ca²⁺ (aq) + 2 HCl (aq) ---> CaCl₂ (s) + H₂ (g)

From the equation of the reaction, the mole ratio of HCL and calcium chloride is 2 : 1

Therefore, moles of calcium chloride that can be produced will be:

The moles of calcium chloride = 5.59 moles * 1/2

The moles of calcium chloride = 2.795 moles

The mass of calcium chloride produced = moles * molar mass

Molar mass of calcium chloride = 111 g/mol

Mass of calcium chloride produced = 2.795 * 111

Mass of calcium chloride produced = 310.245 g
