Valence.
Sodium: Na(2, 8, 1 ) so there is one electron in the highest (3rd) level
Answer. 4sCa = Calcium Atomic number is 20, that means it has 20 proton and 20 electron.1s2,2s2,2p6,3s2,3p6,and 4s2, total of 20 electrons, therefore Highest occupied energy level of Ca is 4s
Transition metals vary in the number of electrons in the highest level. Alkaline earth metals have two electrons in the highest energy level.
2s2
Valence.
The highest occupies energy level in aluminum is the 3rd energy level. Its electron configuration is 1s22s22p63s23p1.
The 3rd energy level is the highest occupied energy level for chlorine with seven electrons.
Magnesium is 1s22s22p63s2 and so the 3rd energy level is the highest occupied level.
Sodium: Na(2, 8, 1 ) so there is one electron in the highest (3rd) level
Sr has two electrons in the highest occupied energy level
A filled highest occupied principal energy level
highest occupied levelread the book, it is in bold and extremely easy to find.
Answer. 4sCa = Calcium Atomic number is 20, that means it has 20 proton and 20 electron.1s2,2s2,2p6,3s2,3p6,and 4s2, total of 20 electrons, therefore Highest occupied energy level of Ca is 4s
The highest energy level is called the "electronegativity".
Transition metals vary in the number of electrons in the highest level. Alkaline earth metals have two electrons in the highest energy level.
