What else can I help you with?
If Ca has a 2 negative charge how many protons does it have?
It has 20 protons, irrespective of its charge.
What charge does an ion have?
An ion can have a positive charge (cation) if it has lost electrons, or a negative charge (anion) if it has gained electrons. The charge of an ion is determined by the number of electrons it has gained or lost during the process of ionization.
How many electrons gained or lost for calcium?
Calcium typically loses 2 electrons to form a stable ion with a 2+ charge. This is because calcium has 2 electrons in its outer shell, and it is energetically favorable for it to lose these electrons to achieve a full outer shell configuration.
The compound CaSO4 ionizes into a calcium ion and a sulfate ion SO4 Calcium has 2 electrons in its outer shell Upon ionization what would you expect the charge on the sulfate ion to be?
The sulfate ion (SO4²-) would have a charge of -2, because it would have gained two electrons to fill its outer shell during ionization.
What is the positive and negative ion for calcium oxide?
The positive ion in calcium oxide is the calcium ion (Ca^2+), which has lost two electrons. The negative ion in calcium oxide is the oxide ion (O^2-), which has gained two electrons.
What does the number next to the ions signify?
Positive and negative a charge
Charge of an atom that has gained electrons?
It is a negative charge
What is the charge on an atom that has gained 5 electrons?
Each electron has a 1- charge, so an atom that has gained 5 electrons has a charge of 5-.
If Ca has a 2 negative charge how many protons does it have?
It has 20 protons, irrespective of its charge.
What charge does an ion have?
An ion can have a positive charge (cation) if it has lost electrons, or a negative charge (anion) if it has gained electrons. The charge of an ion is determined by the number of electrons it has gained or lost during the process of ionization.
What charge does an atom that has gained electrons?
Positive
When an object gains or loses electrons has it an electric charge?
That depends entirely on sign of the charge. If the object gains a positive charge, then that means the object as lost electrons, since electrons are negatively charge. If the charge is negative, then the object has gained electrons. It is also possible that the charge was created by a movement in protons, which are positively charged, in which case the object may not have lost or gained electrons.
How many electrons gained or lost for calcium?
Calcium typically loses 2 electrons to form a stable ion with a 2+ charge. This is because calcium has 2 electrons in its outer shell, and it is energetically favorable for it to lose these electrons to achieve a full outer shell configuration.
Is an isotope an atom with a positive charge?
No, an isotope is an atom with the same number of protons but a different number of neutrons. A positive charge on an atom would indicate it has either lost electrons or gained protons.
What are Atoms that carry an electrical charge called because they have gained or lost electrons?
Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.
The compound CaSO4 ionizes into a calcium ion and a sulfate ion SO4 Calcium has 2 electrons in its outer shell Upon ionization what would you expect the charge on the sulfate ion to be?
The sulfate ion (SO4²-) would have a charge of -2, because it would have gained two electrons to fill its outer shell during ionization.
When an atom in no longer neutral it exists with a charge an atom that has a charge is called a?
When an atom is no longer neutral and has gained or lost electrons, it is called an ion. An atom that has gained electrons will have a negative charge (an anion), while an atom that has lost electrons will have a positive charge (a cation).
