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.
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 many valence electrons must sulfur gain or lose to get 8 valence electrons?
Sulfur has 6 valence electrons. To achieve 8 valence electrons, sulfur must gain 2 electrons to fill its outer shell and satisfy the octet rule.
Which side of the periodic table do elements gain valence electrons?
all the elemants have valence electrons the last number of the elecotrons is the elemets valence electrons
How many valence electrons must bromine gain or lose to get 8 valence electrons?
Bromine's atomic number is 35, so it has 7 valence electrons. To achieve 8 valence electrons and a full outer shell, bromine needs to gain one electron.
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+.
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.
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.
How many valence electrons must sulfur gain or lose to get 8 valence electrons?
Sulfur has 6 valence electrons. To achieve 8 valence electrons, sulfur must gain 2 electrons to fill its outer shell and satisfy the octet rule.
How many electrons phosphorus must gain or lose to have 8 valence electrons?
Phosphorus wants to gain three electrons to have 8 valence electrons.
How will atoms with 5 valence electrons achieve a full set of valence electrons?
They will gain 3 electrons from something with 3 valence electrons.
