If calcium lost two electrons it would have the same number of electrons as?
Argon
How many electrons are gain or lost to form ions for calcium?
two are lost
How many electrons must be gained or lost for calcium to attain a noble-gas electron configuration?
two electrons lost
What is the number of electrons a calcium atom must gain or lose to have 8 valence electrons?
two electron should be lost
Why is the probable charge of an ion of calcium positive?
calcium is a metal which ionizes by electron loss,so a calcium ion has lost to electrons and the positive charge indicates electron deficiency.
If calcium lost two electrons it would have the same number of electrons as?
Argon
How many electrons are gain or lost to form ions for calcium?
two are lost
How many electrons must be gained or lost for calcium to attain a noble-gas electron configuration?
two electrons lost
What is the chemical symbol for calcium that has lost 2 electrons?
Ca2+
In chemical notation Ca2 plus means what?
calcium ions that has lost electrons. It will give away electrons.
Indicate the number of electrons lost or gained by calcium and give the charge of the ion it forms?
loses 2 electrons to form a calcium ion with 2+ charge
How many electrons gained or lost for calcium?
Ca loses electrons. In general metals react in compound by losing some of their electrons, Ca is a metal.
What is the number of electrons a calcium atom must gain or lose to have 8 valence electrons?
two electron should be lost
In chemical notation, the symbol Ca2+ means?
a calcium ion that has lost two electrons.
Why is the probable charge of an ion of calcium positive?
calcium is a metal which ionizes by electron loss,so a calcium ion has lost to electrons and the positive charge indicates electron deficiency.
Why does calcium lose 2 electrons?
The ionic charge is +2: The atom has equal numbers of positively charged protons and negatively charged electrons. The number of protons is the same in the atom and the ion, but in the ion two negative charges have been lost, so that the ion has a net charge of +2.
What ions came from an atom that lost two electrons?
It would be +2. Calcium would be an example
