Yes.
A chloride ion has 18 electrons, giving it a valence of -1.
There are ONLY 2 valence electrons in Co, valence electrons come only from the s orbital and the p orbital, giving only 2 for Cobalt.
6. Valence electrons are the electrons in the s and p orbitals. Keeping this in mind, Se has the 4s orbitals filled (2 electrons) and has 4 electrons filled in the 4p orbital (4p4). 2+4 = 6.
Magnesium ions get their charges by giving away the valence electrons to other atoms.
Counting the 4th shell orbitals and their electrons, Bromine has two 4s electrons and five 4p electrons, giving it a total of 7 valence electrons.
A chloride ion has 18 electrons, giving it a valence of -1.
Fluorine has 7 valence electrons, however, Fluoride (F-) is an anion with a negative charge, giving it one more electron, bumping the number of valence electrons to 8.
There are ONLY 2 valence electrons in Co, valence electrons come only from the s orbital and the p orbital, giving only 2 for Cobalt.
Noble gases do not like giving up electrons. There are 2 electrons in the outer shell of helium and 8 electrons in the outer shell of the other noble gases (group 18 of the periodic table), representing filled shells.
There are ONLY 2 valence electrons in Co, valence electrons come only from the s orbital and the p orbital, giving only 2 for Cobalt.
Two- Since it has six valence electrons, it can form two covalent bonds, making the valence two. If it is easier to think about it this way, eight valence electrons would stabilize the element. Eight minus six is two, giving us the same answer as before.
Radon, being a noble gas, has 8 valence electrons, giving it a stable octet.
6. Valence electrons are the electrons in the s and p orbitals. Keeping this in mind, Se has the 4s orbitals filled (2 electrons) and has 4 electrons filled in the 4p orbital (4p4). 2+4 = 6.
Magnesium ions get their charges by giving away the valence electrons to other atoms.
All alkali metals have 1 valence electron that is it loses when forming compound, giving it a charge of +1
a chemical bond in which valence electrons are shared between atoms giving each of them a full valence shell is a covalent bond.
Counting the 4th shell orbitals and their electrons, Bromine has two 4s electrons and five 4p electrons, giving it a total of 7 valence electrons.
