How does the size of a magnesium ion with a 2 positive charge compare with that of a sodium ion with a single positive charge?
A magnesium ion will be smaller because there will be a greater Zeff on the electrons in the magnesium ion due to a greater number of protons in the nucleus.
How many electrons dose Mn plus 2 have?
If the charge is positive number of electron will be 40, if the charge is negative it will be 44.As molybdenum has atomic number 42.
Is Na2SO4 a ionic compound?
Yes. The charge on Na (sodium) ions is 1+ and the charge on a SO4 (sulfate) ion is 2-. So to balance out the charges 2 sodium ions are needed for every sulfate ion.
How does sodium atom form an ion?
A sodium atom becomes a sodium ion, when a neutron is added to the nucleus.
What are the 2 types of electric charges?
Positive charge and negative charge
Why does a element have a plus 2 charge?
An element you have a +2 charge It is had lost electrons. It would have to lose the same number of electrons that its positive charge is. So it would have lost 2 electrons.
Does hydrogen carbonate contain a positive charge?
no, i don't think it does.this is beause sodium hydrogencarbonate (which is actually sodium bicarbonate, used for cooking/baking?) is an ionic compound. since sodium has a positive charge, hydrogencarbonate should have a negative charge.at least that's what i think. hope that helps. Hydrogencarbonate has an overall charge of -1, meaning (HCO3)-. This is because (CO3)2- and H+ makes it -1, if you do the math :)

What is the charge of sodium oxide?
Sodium oxide is a neutrally charged molecule. However, it is composed of two positive ions of sodium and one negative ion o of oxygen. They form an IONIC Bond. 2Na^+ + O^(2-) = Na2O(s)
What is the net charge of the ionic compound sodium sulfide?
Sodium chloride is neutral.
Did Ca plus plus gain an electron to produce the charge?
Ca2+ is positively charged. Remember that an electron is a particle with negative charge; therefore, the element Calcium (Ca) has LOST 2 electrons in order to be positive 2.
Does the sodium ion and the neon atom have the some atomic number number of electrons number of charge?
The sodium ion has one more proton than neon and 2 more neutrons. It has a positive charge where neon is neutral but they both do have 10 electrons
How many electrons dose Mn plus 2 have?
If the charge is positive number of electron will be 40, if the charge is negative it will be 44.As molybdenum has atomic number 42.

What is different between a sodium ion and a neon atom?
The sodium ion has one more proton than neon and 2 more neutrons. It has a positive charge where neon is neutral but they both do have 10 electrons
How does sodium atom form an ion?
A sodium atom becomes a sodium ion, when a neutron is added to the nucleus.
What is the charge of the ion that calcium would form?
Calcium is in group 2. Therefore it's most probable charge is Ca2+.
