Remember the talk about the "outer electrons" you learned about? Sodium (Na) has 1 electron in the outer most electron orbital. Calcium (Ca) has, you guessed it, 2 electrons in its' outer most electron orbital. Can you explain the rest to yourself? Remember they had a neutral charge before becoming ionic.
What else can I help you with?
Is calcium oxide a positive or negative ion?
Calcium oxide is a compound composed of calcium (Ca) and oxygen (O) ions. Calcium has a 2+ charge, while oxygen has a 2- charge. Therefore, calcium oxide is made up of a positive calcium ion (Ca2+) and a negative oxide ion (O2-).
Is calcium hydroxide a polar substance?
Calcium hydroxide is an ionic compound, therefore it has no polarity.
If an object has more electrons than protons it has what type of charge?
Since protons have a positive charge and electrons have a negative charge, an atom with more protons than electrons would have a positive charge. Note that an atom with this kind of imbalance is known as an ion.
Electrons carries a positive or negative charge?
Yes, they have a negative charge. Protons have a positive charge and neutrons have no charge, they are neutral.
Why is the probable charge of an ion of calcium positive?
The probable charge of an ion of calcium is positive because calcium readily loses 2 electrons to achieve a stable electron configuration similar to a noble gas, which is energetically favorable for the atom. This results in the formation of a Ca2+ ion with a positive charge.
Is calcium oxide a positive or negative ion?
Calcium oxide is a compound composed of calcium (Ca) and oxygen (O) ions. Calcium has a 2+ charge, while oxygen has a 2- charge. Therefore, calcium oxide is made up of a positive calcium ion (Ca2+) and a negative oxide ion (O2-).
How is the bonding in calcium oxide different from the bonding in sodium chloride?
calcium is mdonating one electron to each chloride. This makes the calcium a positive charge and the chloride a negative charge. This is called ionic bonding (CaCl2)
What particles has a negative charge and which has a positive charge?
Negative charge = electron Positive charge = positron Positive charge = proton
What charge electron charge positive or negative?
Electrons carry a negative charge to balance out the positive charge of the proton.
Does all matter have a negative or positive charge?
No, not all matter has a negative or positive charge. Matter can be neutral, meaning it has an equal number of positive and negative charges, such as in most atoms. Charged particles exist in matter, such as electrons with a negative charge and protons with a positive charge.
Is calcium hydroxide a polar substance?
Calcium hydroxide is an ionic compound, therefore it has no polarity.
What is the difference between a negative and a positive?
positive ions carry positive charge and negative ions carry negative charge
Is an atom a negative charge or a positive charge?
An atom with positive charge is cation.An atom with negative charge is anion.
Is b a negative or positive charge?
A positive charge
When a proton is positive an electron is?
Negative. Protons have a positive charge while electrons have a negative charge.
What is calcium's electrical charge?
positive charge, ca2+
Which particle proton neutron or electron have a positive charge?
proton positive neutron neutral electron negative
