Aluminum has 3 valence electrons.
In the compound Al₂O₃, there are two aluminum (Al) atoms and three oxygen (O) atoms. Aluminum has 3 valence electrons, so 2 Al atoms contribute a total of 6 valence electrons. Oxygen has 6 valence electrons, so 3 O atoms contribute 18 valence electrons. Therefore, the total number of valence electrons in Al₂O₃ is 6 + 18 = 24 valence electrons.
Aluminum has 3 valence electrons.
A neutral atom of aluminum has 3 valence electrons.
Aluminum has 3 valence electrons.
Aluminium has three valence electrons.
Alkaline earth metals are group 2 elements and have 2 valence electrons.
there are 3 valence electrons in the atom of aluminum
Oxygen atoms have 6 valence electrons, while sulfur atoms have 6 valence electrons as well.
An aluminum (Al) atom has 13 electrons. In chemistry, the behavior of atoms is primarily determined by their valence electrons, which are the electrons in the outermost shell. For aluminum, there are three valence electrons in its outer shell (3s²3p¹), which are involved in chemical bonding and reactions. Therefore, we expect these three valence electrons to participate in chemistry for an Al atom.
There are 3 electrons in the outermost level of aluminum. Aluminum is in Group 13 and has 3 valence electrons.
Oxygen has six valence electrons.
