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?
It must gain two electrons.
How many valence electrons must bromine gain or lose to get 8 valence electrons?
Bromine must gain one electron
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
Will the valence electrons of calcium give or take away electrons?
Calcium atom will generally lose two electrons to form Ca2+ ions. Calcium will not accept (gain) electrons.
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-.
What is the number of electrons a calcium atom must gain or lose to have 8 valence electrons?
two electron should be lost
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.
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+.
How many valence electrons must sulfur gain or lose to get 8 valence electrons?
It must gain two electrons.
How many electrons does phosphrous have to gain or loose to have 8 valence?
P has 5 valence electrons so it can gain 3 electrons or lose 5 electrons to have a full valence shell.
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 do atoms gain a charge?
An atom willreceive a charge when it becomes ionized. If the atom looses one of its electrons (-), then there are more protons (+) and it becomes a+1 charge (positive). If the atom gains an electron, then there are more electrons and it becomes a -1 (negative) charge. It depends on the electrons in the valence level (outer level) to decide if it will gain or lose 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.
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.
