A calcium atom is larger than a calcium ion because?
When it becomes an ion it is loosing electrons causing the effective nuclear charge to increase which draws the remaining electrons in closer which makes the ion smaller than the atom.
Who has the largest radius calcium atom or calcium ion?
The radius of a cadmium atom is smaller than the radium of a mercury atom. The trend for atomic radius is that the radius becomes larger toward the left side of the row and toward the bottom of the group.
The element that forms a 2 plus ion with the same electronic configuration as Ar?
Calcium
Which cation may have atomic number 20 and a charge of 2?
The element is calcium and the cation is Ca2+ ion
What element is the metallic component of the mineral marble?
Marble is mainly composed of CaCO3 (calcium carbonate, limestone) in which calcium is the metallic ion.
What can be concluded if an ion of an element is smaller than an atom of the same element?
The ion is positively charged because it has fewer electrons than the atom.
A calcium atom is larger than a calcium ion because?
When it becomes an ion it is loosing electrons causing the effective nuclear charge to increase which draws the remaining electrons in closer which makes the ion smaller than the atom.
Why is calcium fluoride have a smaller boiling point then magnesium fluoride?
The calcium ion is larger than the magnesium ion and so the charge on it is less dense. This makes it less attracted to the fluoride ions
Is CaCl2 polyatomic ion?
No, it is a salt made of 1 Ca2+ ion and 2 Cl- ions with no total net charge. Hope this helps
A calcium ion has the same electron configuration as what other element?
Considering the normal calcium ion Ca2+ it has the same electronic configuration as the noble gas Argon.
What is the formula for calcium ion?
Calcium ion: Ca2+ Chloride ion: Cl-
Who has the largest radius calcium atom or calcium ion?
The radius of a cadmium atom is smaller than the radium of a mercury atom. The trend for atomic radius is that the radius becomes larger toward the left side of the row and toward the bottom of the group.
When Mg forms an ion will the ion be smaller or longer than the atom?
The ion has a smaller diameter.
What is the calcium ion?
it is calcium which has 1 electron less than normal
What type of ion would calcium form?
Calcium is a group 2 element, and so it will form a cation, Ca 2+.
What is the oxidation number for calcium and nitrate?
Calcium is a element. Nitrate is a ion. Calcium shows +2.
The element that forms a 2 plus ion with the same electronic configuration as Ar?
Calcium
