How many electrons must calcium gain or lose to have 8 valence electrons and what charge of the ion will it make?
Calcium has two valence electrons and needs to lose both to achieve a stable electron configuration, resulting in 8 valence electrons in the nearest noble gas configuration (argon). By losing these two electrons, calcium forms a cation with a charge of +2, resulting in a Ca²⁺ ion.

How many electrons does calcium need to get eight valence electrons?
Calcium has two valence electrons in its outer shell. To achieve a stable octet configuration of eight valence electrons, it needs to lose these two electrons rather than gain any. Therefore, calcium does not need to gain any electrons; instead, it will typically lose two to achieve stability.
How many valence electrons must calcium lose or gain to have 8 valence electrons?
It loses 2 electrons to obtain the argon configuration of 8 valence electrons.
What is the net charge of silicon if it gain three valence electrones?
Silicon typically has four valence electrons and is neutral with no net charge. If it gains three additional valence electrons, it will have a total of seven valence electrons. This would result in a net charge of -3, as gaining electrons gives the atom a negative charge.
How do you find the charge of an atom with 7 valence electrons?
The halogens, group 17, have 7 valence electrons. When they form ions, they gain 1 more valence electron and become ions with a charge of 1-.
What is the number of electrons a phosphorus atom must gain or lose to have 8 valence electrons and what is the resulting ion charge?
A phosphorus atom has 5 valence electrons and needs to gain 3 more to achieve a total of 8 valence electrons. By gaining 3 electrons, phosphorus becomes negatively charged, resulting in a charge of -3. Therefore, the resulting ion is a phosphide ion (P³⁻).
How many electrons does calcium need to get eight valence electrons?
Calcium has two valence electrons in its outer shell. To achieve a stable octet configuration of eight valence electrons, it needs to lose these two electrons rather than gain any. Therefore, calcium does not need to gain any electrons; instead, it will typically lose two to achieve stability.
How many valence electrons must calcium lose or gain to have 8 valence electrons?
It loses 2 electrons to obtain the argon configuration of 8 valence electrons.
For calcium ca write the numbers of electrons it must gain or lose to have 8 vlance electrons then calculate the charge of the ion that would form?
Ca must lose 2 electrons to have a complete 3n shell, which has 8 valence electrons. The ion would have a charge of 2+: Ca^2+.
What is the net charge of silicon if it gain three valence electrones?
Silicon typically has four valence electrons and is neutral with no net charge. If it gains three additional valence electrons, it will have a total of seven valence electrons. This would result in a net charge of -3, as gaining electrons gives the atom a negative charge.
Will the valence electrons of calcium give or take away electrons?
The valence electrons of calcium will tend to give away electrons, as it is an alkaline earth metal with two valence electrons. This makes it more energetically favorable for calcium to lose these two electrons and achieve a full outer electron shell by forming a 2+ cation.
How many electrons will sulfur gain or lose What will its charge be?
Sulfur, with its 6 valence electrons, will gain 2 electrons to achieve a stable octet configuration, resulting in a charge of -2.
How do you find the charge of an atom with 7 valence electrons?
The halogens, group 17, have 7 valence electrons. When they form ions, they gain 1 more valence electron and become ions with a charge of 1-.
How does an atom keep its charge?
An atom's charge changes when it gains or loses electrons. Atoms naturally tend to lose or gain electrons to level out at eight valence electrons (valence electrons are electrons in the outermost energy level), so the only atoms that keep their charge are ions with eight valence electrons or the Noble Gases, atoms on the far right of the periodic table that have eigth valence electrons and a nuetral charge.
What is the number of electrons a calcium atom must gain or lose to have 8 valence electrons?
A calcium atom must lose 2 electrons to have 8 valence electrons, achieving a full outer shell and stability. Calcium is in group 2 of the periodic table, so it has 2 valence electrons originally. By losing 2 electrons, it will have a stable electron configuration similar to a noble gas.
What is the number of electrons a phosphorus atom must gain or lose to have 8 valence electrons and what is the resulting ion charge?
A phosphorus atom has 5 valence electrons and needs to gain 3 more to achieve a total of 8 valence electrons. By gaining 3 electrons, phosphorus becomes negatively charged, resulting in a charge of -3. Therefore, the resulting ion is a phosphide ion (P³⁻).
How many electrons must phosphorus p gain or lose to have 8 valence electrons?
Phosphorus wants to gain three electrons to have 8 valence electrons.
How many electrons would calcium have to lose or gain to have to have 8 valence electrons?
Calcium would need to lose 2 electrons to have 8 valence electrons. This is because calcium has 2 valence electrons in its outer shell, and by losing these 2 electrons, it can achieve a stable octet configuration like the noble gas argon.
