What else can I help you with?
Calcium has an atomic number of 20. it can form an ion by losing 2 electrons. what would it's chargde be?
If calcium loses 2 electrons, it will have a positive charge of +2 because it loses 2 negatively charged electrons, leaving behind 20 positively charged protons.
What ions came from an atom that lost two electrons?
An atom that loses two electrons will form a cation with a +2 charge. For example, sodium can form a Na+ cation by losing two electrons.
If calcium lost two electrons it would have the same number of electrons as?
If calcium lost two electrons, it would have the same number of electrons as argon. Calcium has 20 electrons in its neutral state, and losing two electrons would leave it with 18 electrons, which is the same as argon.
If calcium is most happy with a charge of 2 how many electrons would it have?
The neutral atom of calcium has 20 electrons; the cation Ca2+ has 18 electrons.
What Ionic bond would form between F and CA?
An ionic bond between F (fluorine) and Ca (calcium) would form when fluorine gains an electron to achieve a stable octet configuration and becomes a fluoride ion (F-), while calcium loses two electrons to become a calcium ion (Ca2+). The attraction between the oppositely charged ions leads to the formation of calcium fluoride (CaF2) crystal lattice.
Would calcium gain or lose electrons?
calcium loses two electrons, becoming a +2 ion
Predict the charge that a calcium ion would have?
A calcium ion (Ca^2+) would have a charge of +2, as it loses two electrons to achieve a stable electron configuration.
Calcium has an atomic number of 20. it can form an ion by losing 2 electrons. what would it's chargde be?
If calcium loses 2 electrons, it will have a positive charge of +2 because it loses 2 negatively charged electrons, leaving behind 20 positively charged protons.
Does calcium become a monatomic cation by gaining two electrons?
No, gaining two electrons would give calcium a full outer shell and make it a stable anion, not a cation. Calcium typically loses two electrons to become a monatomic cation with a 2+ charge.
Would you expect calcium to gain or lose electrons in a chemical reactions?
Calcium is expected to lose electrons in a chemical reaction because it is a metal located in group 2 of the periodic table, which typically loses electrons to achieve a stable electron configuration. Calcium will typically form a 2+ cation by losing 2 electrons in reactions.
What ions came from an atom that lost two electrons?
An atom that loses two electrons will form a cation with a +2 charge. For example, sodium can form a Na+ cation by losing two electrons.
If calcium lost two electrons it would have the same number of electrons as?
If calcium lost two electrons, it would have the same number of electrons as argon. Calcium has 20 electrons in its neutral state, and losing two electrons would leave it with 18 electrons, which is the same as argon.
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 scientific element has 20 electrons?
Calcium has twenty electrons in each atom.
Why does a calcium ion have a charge of plus 2?
A calcium ion has a charge of +2 because it has lost two electrons to achieve a stable electron configuration. Calcium typically has 20 protons and 20 electrons, but when it loses two electrons, it has 20 protons but only 18 electrons, resulting in a net charge of +2.
If calcium is most happy with a charge of 2 how many electrons would it have?
The neutral atom of calcium has 20 electrons; the cation Ca2+ has 18 electrons.
What is the electric charge on the calcium ion in the compound calcium oxide?
The electric charge on the calcium ion in calcium oxide is 2+. This is because calcium (Ca) forms a cation with a charge of 2+ when it loses two electrons to achieve a stable electronic configuration.
