the answer is 28
Barium has 0 unpaired electrons. It has a full outer shell of electrons, which is why it is a stable element.
BARIUM
There are four protons. Also four neutrons and four electrons
Fluorine is an element and barium is also an element. There is no fluorine in barium and not barium in fluorine.
Barium's atomic number is 56. Thus, an atom of barium has 56 protons in it. To keep it electrically neutral then, a barium atom must also have 56 electrons per atom.
Barium has 0 unpaired electrons. It has a full outer shell of electrons, which is why it is a stable element.
This element is xenon.
Barium is a group 2 element. All group 2 elements have 2 valence electrons. Thus, barium has 2 valence electrons.
BARIUM
There are four protons. Also four neutrons and four electrons
There are 2 valence electrons in Barium.
Barium has 56 electrons.
Krypton (Kr) has a total number of 36 electrons, which is the same as the number of core electrons in barium (Ba).
A barium atom has two valence electrons.
No. Barium is a Group 2 element, and as such will lose its two valence electrons to form a Ba2+ ion when forming an ionic compound.
A neutral barium atom has 56 electrons. This is because the atomic number of barium is 56, which corresponds to the number of electrons it has when it is electrically neutral.
Barium is monatomic so 56.
