Why is nitrogen ion larger than fluoride ion?
The nitride ion has a larger negative charge than the fluoride ion and a smaller positive charge in its nucleus, which means a greater repulsion within the electron shells and a lesser attraction to the nucleus.
What has a larger atomic radius Cl ion or Ca ion?
Calcium has the larger atomic radius than chlorine. Calcium has four energy levels, whereas chlorine has three energy levels. The higher the energy level, the farther it is from the atomic nucleus.
How can you say that magnesium ion and sodium ion are similar in size?
Sodium ion is larger than magnesium ion. The electrons are more tighly bound in Mg2+. On a "diagonal relationship" Li and Mg are similar in size as are sodium and calcium
When iodine becomes an ion is the ion larger or smaller?
Iodine gains one electron to form iodide ion. The size of iodide ion is larger than the size of iodine atom.
Is the size of a positive ion generally bigger or smaller than the size of the neutral form which it forms?
We are working on this in Physical Science class. A negative ion is larger then its parent atom. A positive ion is smaller then its parent 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 nitrogen ion larger than fluoride ion?
The nitride ion has a larger negative charge than the fluoride ion and a smaller positive charge in its nucleus, which means a greater repulsion within the electron shells and a lesser attraction to the nucleus.
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
What has a larger atomic radius Cl ion or Ca ion?
Calcium has the larger atomic radius than chlorine. Calcium has four energy levels, whereas chlorine has three energy levels. The higher the energy level, the farther it is from the atomic nucleus.
How can you say that magnesium ion and sodium ion are similar in size?
Sodium ion is larger than magnesium ion. The electrons are more tighly bound in Mg2+. On a "diagonal relationship" Li and Mg are similar in size as are sodium and calcium
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.
What is the calcium ion?
it is calcium which has 1 electron less than normal
Which is larger an arsenic ion or a bromine ion?
An arsenide ion is larger than a bromide ion, but a bromide ion is larger than an arsenic ion. Recall that arsenic can have several oxidation states. It can be a cation or an anion.
How is are the configurations of calcium and a calcium ion similar?
They are the same in that they have the same number of protons and neutrons. However, the number of electrons is different. The calcium 2+ ion has two less electrons than the normal calcium atom.
CaN2 what is the oxidation number of N?
The actual chemical formula for calcium nitride is Ca3N2 and not CaN2. The oxidation numbers are +2 for each calcium and -3 for each nitrogen (as it is nitride ion)
When iodine becomes an ion is the ion larger or smaller?
Iodine gains one electron to form iodide ion. The size of iodide ion is larger than the size of iodine atom.
Is the size of a positive ion generally bigger or smaller than the size of the neutral form which it forms?
We are working on this in Physical Science class. A negative ion is larger then its parent atom. A positive ion is smaller then its parent atom. =]
