How many valence electrons does calcium carbonate have?
Calcium carbonate has 16 valence electrons. Calcium contributes 2 valence electrons, while each oxygen atom contributes 6 valence electrons.
How many valence electrons are there in an atom of arsenic iodine calcium tin and sulfur?
Arsenic: 5 valence electrons Iodine: 7 valence electrons Calcium: 2 valence electrons Tin: 4 valence electrons Sulfur: 6 valence electrons
How many valence electrons do each what elements have boron gold krypton and calcium?
Boron has 3 valence electrons, gold has 1 valence electron, krypton has 8 valence electrons, and calcium has 2 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom.
How many valence electrons in calcium ion?
Type your answer here... The number of valence electrons in calcium is 20, because it's almost the same thing as it's atomic number.
How many electrons would calcium have to lose or gain to have to have 8 valence electrons?
Calcium would need to lose 2 electrons to have 8 valence electrons. This is because calcium has 2 valence electrons in its outer shell, and by losing these 2 electrons, it can achieve a stable octet configuration like the noble gas argon.
