How many electrons does the neutral atom gain or lose when each ion forms?

Question

a. Cr^+3
b. P^-3
c. Li^+1
d. Ca^+2
e. Cl^-1
f. O^-2

What exactly am I looking for here? Just please explain what I'm looking for so I can find the answers.

Answer 1

a.-3 electrons
b.+3 electrons
c.-1 electron
d.-2 electron
e.+1 electron
f.+2 electron
It is opposite as most people believe because an electron has a negative charge.

Answer 2

The atoms are impartial because of the fact the kind of electrons (destructive) and protons (helpful) is equivalent. while the atom looses one electron, there is one proton in extra (for the neutrality) and the atom is charged helpful (a million+), loss of two electrons = charge 2+. same for the choice, the atom recommendations up one electron, now there is the destructive charge in extra and the atom is destructive (a million-). Take it from the different facet: an atom is charged 3+, there are 3 unneutralized protons, it has lost 3 electrons.

Answer 3

a. Cr loses 3 electrons to form Cr3+.
b. P gains 3 electrons to form P3-.
c. Li loses 1 electron to form Li+.
d. Ca loses 2 electrons to form Ca2+.
e. Cl gains 1 electron to form Cl-.
f. O gains 2 electrons to form O2-.

All in all, the neutral atom loses the same number of electrons as its ion's charge if the charge is positive. If an ion's charge is negative, the neutral atom gains the same number of electrons as the charge on the ion to form the ion.

Answer 4

Cr3 would have to lose how many electrons to gain a +3 charge?

O2 would have to gain how many electrons to gain a -2 charge?

electrons have a -1 charge
