A calcium atom will normally lose its two valence electrons, which have principal quantum number 4, to a more electronegative atom when forming a compound. When this happens, the already filled electron shell with principal quantum number 3 becomes the outer shell of the resulting calcium cation, and this cation has the electronic structure of the noble gas preceding calcium in the Periodic Table, neon

How many electrons does He and Ca have in its outer shell?
Helium (He) and Calcium (Ca) both have 2 valence electrons.
Number of valence electrons calcium lose?
The calcium atom (Ca) loses two valence electrons to form a calcium ion (Ca2+).
Does calcium fill its shell by giving up two electrons?
Calcium has 2 valence electrons in its outer shell. To fill its shell, calcium gives up these 2 electrons to achieve a stable octet configuration, forming a 2+ cation.
What are found in an atoms outer shell?
Electrons are found in an atom's outer shell. The outer shell, also known as the valence shell, is where the electrons involved in chemical reactions and bonding are located. The number of electrons in the outer shell determines the atom's chemical properties.
Does carbon have three electrons in its valence shells yes or no?
No. Carbon has 4 electrons in its outer shell (valence shell).

Does calcium fill its shell by giving up two electrons?
Calcium has 2 valence electrons in its outer shell. To fill its shell, calcium gives up these 2 electrons to achieve a stable octet configuration, forming a 2+ cation.
What is a valence shell is?
The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.

What are valence elecdtrons?
valence electrons are the electrons on the outer-most shell of electrons
