how many valence electrons does ca have

Thoughts? The valance electrons in carbon is 4, and when it is diatomic the valence electrons would be 4*2=8 so the valence electrons would be 8 in C2. Learning about electron configuration and subatomic shells actually reveal how many valence electrons and how many electrons overall an element has...it might seem kind of weird the first time you learn it...but it all eventually will fall into place : ) 0 2 0.

This Site Might Help You. How many valence electron does Ca have? This completes those shells. While valence electrons across a period incrementally climb by one, the number of shells remain the same. Calcium's atomic number is 20. O2 gas doesn't have any valance electrons. It will be arranged in a manner that is 2, 4. Two oxygen atoms are bound covalently to get rid of valency and form O2 gas.

Oxygen atom need 2 more electrons to get rid of valency. Calcium has 2 valence electrons. Login to reply the answers Post; Anonymous. Relevance. It came up on a test and I put none but other people said they put 8. 2 Using orbital notation the electron structure is: 1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(2) You can see that there are 2 electrons in the outer energy level and these are the valence electrons. There are 20 electrons, total, in calcium. Oxygen is in 6th column and they have 6 valance electrons. How many valence electrons does Ca+2 have in a Lewis Dot Diagram?
