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.
What is the symbol for the atom that has 40 electrons?
Technically, any atom could have 40 electrons, but it would have a very weird charge. However, Zirconium has 40 electrons without being an ion.
Number of valence electrons calcium lose?
The calcium atom (Ca) loses two valence electrons to form a calcium ion (Ca2+).
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.
How many neutrons are in calcium oxide?
Depends on what you mean by number of electrons. Calcium has 20 electrons and oxygen has 8 electrons for a total of 28 electrons. But if you mean how many VALENCE electrons, then the calcium has 2 and the O has 6 for a total of 8 valence electrons.
How many electrons does the calcium ion lose from an atom?
It loses 2 electrons.
How many electrons do calcium has?
Calcium, as an element, has 20 electrons. But when becomes an ion, it loses two electrons, becoming Ca+2. Therefore, as an ion, calcium has only 18 electrons.18
What atom has the same number of electrons as in ion of calcium?
calcium forms Ca+2 ion having 18 electrons which are equal to the electrons of noble gas Argon.
If a calcium atom has twenty protons then how many electrons would it have?
20 (any more or less and it would be an ion not an atom)

Number of valence electrons calcium lose?
The calcium atom (Ca) loses two valence electrons to form a calcium ion (Ca2+).
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.
Calcium and Bromine have formed a bond Leading up to this calcium gave up electrons It was a negative ion shared ion positive ion neutral atom?
a negative ion
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.
How many valence electrons are in a chlorine atom and a chloride ion?
There are 7 valence electrons in chlorine atom and 8 valence electrons in chloride ion.
Why does calcium lose 2 electrons?
The ionic charge is +2: The atom has equal numbers of positively charged protons and negatively charged electrons. The number of protons is the same in the atom and the ion, but in the ion two negative charges have been lost, so that the ion has a net charge of +2.
