S2- Cl1- K1 plus and Ca2 plus are all with Ar?
They have the same electron configuration as argon, which means they are isoelectronic with argon.
S2- Cl1- and Ca2 plus are all with Ar?
They have the same electron configuration as argon, which means they are isoelectronic with argon.
Does K plus have a smaller radius than Ca2 plus?
I would not think so as their natural state radius is so close. Ca(2+) loses two electrons, so I think it would have the smaller ionic radius.
Which is more reactive Mg or Ca Why?
Calcium is more reactive. In the periodic table, Calcium is directly below Magnesium, which means that a calcium atom is larger than a magnesium atom. This means that the electrostatic attraction between the valence electrons of calcium and the nucleus is weaker than in magnesium(larger distance, smaller force). So, the valence electrons of calcium can easily be lost to form Ca2+ , which translates to Calcium being the more reactive metal.
What is the difference between a mmol and a mEq?
Milli equivalents and milli moles are units used to describe molecular or ionic grades of concentration. A milli equivalent or mEq is derived by dividing the concentration in millimol or mmol by the valency of the ion involved.Eg: 1 mEq of sodium Na+ = 1 mmol of sodium (because valency is 1)whereas 1 mEq of Ca2+ = .5 mmol of calcium. (because valency is
In chemical notation, the symbol Ca2+ means?
a calcium ion that has lost two electrons.
The chemical symbol Ca2 plus refers to?
An isotope of calcium
When you have Ca2 plus plus in chemistry what does the 2 plus signs mean?
The 2 plus signs indicate that the calcium ion (Ca2+) has a charge of +2. This means that the calcium atom has lost 2 electrons, giving it a positive charge of 2. It is an ion that is positively charged and forms in certain chemical reactions.
The correct formula for Ca2 plus reacting with NO21-?
In this reaction, Ca2+ reacts with NO2^1- to form Ca(NO2)2. The balanced chemical equation for this reaction is: Ca2+ + 2NO2^- → Ca(NO2)2.
What is the chemical formula for combining Ca2 plus AsO3- 4?
The chemical formula for combining Ca2+ and AsO3^4- ions would be Ca3(AsO3)2. This shows that three calcium ions (Ca2+) will combine with two arsenite ions (AsO3^-4).
S2- Cl1- K1 plus and Ca2 plus are all with Ar?
They have the same electron configuration as argon, which means they are isoelectronic with argon.
The chemical symbol Ca2 plus refers to the?
Calcium ion with a +2 charge.
S2- Cl1- and Ca2 plus are all with Ar?
They have the same electron configuration as argon, which means they are isoelectronic with argon.
What is the chemical formula for a compound made up of Ca2 plus and (PO4)3 and minus?
For example a calcium phosphate as Ca3(PO4)2.
What is the chemical formula for Ca2 and S2?
Calcium sulfide has the chemical formula CaS.
WHAT IS THE DIFFERENCE BETWEEN CA AND CA2 plus?
Ca refers to calcium, which is a chemical element with the atomic number 20. Ca2+ refers to a calcium ion that has lost two electrons, resulting in a 2+ charge. The main difference is that Ca represents the neutral form of calcium, while Ca2+ represents the positively charged ion form.
What is the name of the ionic compound Ca2 plus F-?
The ionic compound formed by Ca2+ and F- ions is calcium fluoride.
