When calcium is ionized, it loses two electrons to form Ca2+. The calcium ion is smaller than elemental calcium because the positively-charged nucleus holds tightly to to the lesser negative charge.

∙ 15y agoThe Calcium atom, because it's in Group 2 on the Periodic Table, has 2 electrons in it's outer shell. It will therefore give away the two electrons to get a full outer shell and become more stable. The electronic arrangement will then go from Ca - 2,8,8,2 to: Ca2+ ion - [2,8,8]2+ Actually it would go from: 1s22s22p63s23p64s2 to: 1s22s22p63s23p6 (sorry to be pedantic)

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
How many valance electrons are transferred from the calcium atom to iodine in the formation of calcium iodide?
A calcium atom will transfer its two valence electrons to two separate iodine atoms in the formation of calcium iodide. The calcium atom becomes a Ca2+ ion, and each iodine atom becomes a 1- iodide ion. The electrostatic force of attraction between the oppositely charged ions forms ionic bonds between the ions.Ca + I2 --> Ca + I + I --> Ca2+ + I- + I- --> CaI2Overall reaction:Ca + I2 ---> CaI2
How many valence elections are transferred from the calcium atom to iodine in the formation of the compound calcium iodine?
One calcium atom will transfer one of each of its two valence electrons to one each of two iodine atoms. In the process, the calcium atom becomes a calcium ion with a 2+ charge, and each iodine atom becomes an iodide ion with a 1- charge. The opposite charges between the iodide and calcium ions form an electrostatic attraction called an ionic bond, forming the ionic compound calcium iodide. Ca + I2 ---> I- + Ca2+ + I- ---> CaI2
When calcium and chloride bond to make calcium chloride does calcium become an anion and chloride a cation?
calcium becomes the main ion and chloride the secondary ion
Why is Calcium Chloride covalent?
When Ca and Cl combine with each other, the electron transfer takes place from Calcium atom to Chlorine atom (i.e from Ca to Cl). In other words, the Calcium atom (Ca) loses 2 electrons and the Chlorine atoms (Cl) gains 1-1 electrons. Due to this, the Calcium becomes a positive ion (Ca 2+) and Chlorine becomes a negative ion (Cl –).
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.
What happened to an Atom when it loses an electron?
It loses a negative charge and then becomes a positive ion
What happens when atoms loses an electron?
AnswerA neutral atom that loses an electron becomes an ion that is positively charged (also called a cation).When a calcium atom loses two electrons it becomes positively charged.
To form an ion what does a calcium atom gain or loose?
An atom of Calcium will lose an electron to become a posotive ion.
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 happens when atom looses electron?
If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.
An atom becomes an ion by losing or gaining?
An atom can become an ion by either gaining or losing electrons. If it gains electrons, it becomes an anion. If it loses electrons, it becomes a cation. An ion is merely an atom with a charge, either positive or negative.
How many electrons are in a calcium atom and in a calcium ion?
Calcium atom 20 e- Ca2+ 18 e-
When an atom gains an electron the atom becomes an ion that?
yes...on gaining an electron, the atom becomes an anion i.e. negatively charged ion.
