What else can I help you with?
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.
In chemical notation Ca2 plus means what?
calcium ions that has lost electrons. It will give away electrons.
S2- Cl1- and Ca2 plus are all with Ar?
They have the same electron configuration as argon, which means they are isoelectronic with argon.
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
Which ion has the smallest ionic radius Mg2 plus or Ca2 plus?
Mg2+ has the smaller ionic radius compared to Ca2+ because as you move down a group in the periodic table, the ionic radius increases due to the addition of electron shells. Mg and Ca are in the same group, but Ca has more electron shells than Mg, resulting in a larger ionic radius for Ca2+.
Li or Ca2 which cation is smaller?
Li+ is smaller than Ca2+
Is ca plus 2 or mg plus 2 larger?
The Ca2+ ion is larger than the Mg2+ ion. The ionic radii are: 86pm for the Mg2+ and 114pm for the Ca2+. Besides the fact that the Ca2+ has more electrons this can be explained by the principle of electron shielding. Electron shielding is when lower level electrons block the EFC(effective nuclear charge) from effecting the valence electrons of an ion. Ca2+has more electrons than Mg2+ so more electron shielding occurs.
Which particle is bigger Ca or Ca2 plus?
The particle Ca2+ is bigger in size compared to the Ca particle. This is because Ca2+ has an additional charge compared to Ca, which results in a larger ionic radius due to increased electron-electron repulsion that can overcome the attractive force between the nucleus and electrons.
Is Ca2 plus a cation?
Yes it is a cation which is an ion with fewer electrons than protons, giving it a positive charge.
How many electron ca2 plus?
Calcium has atomic number 20. A neutron calcium atom therefore has 20 protons and 20 electrons. Ca2+ has a charge of positive 2, so it must have 2 more protons than electrons. Ca2+ has 18 electrons.
What is the name of the ionic compound Ca2 plus F-?
The ionic compound formed by Ca2+ and F- ions is calcium fluoride.
The chemical symbol Ca2 plus refers to?
An isotope of calcium
Is the charge of Ca2 plus correct?
The charge of Ca2+ is correct. Calcium typically oxidizes to form a 2+ cation by losing two electrons.
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.
How many centimoles of charge of Ca2 plus are needed to replace 2 centimoles Na plus?
1
What is the name of the ion Ca2 plus?
Ca2+ is a cation formed by Calcium to become stable and attain the noble gas configuration of Argon. Calcium forms this cation by losing two electrons
