That depends on how much of the substance you have. Assuming you mean in one formula, the answer is 7.
Scandium hydroxide - Sc(OH)3 - has 7 atoms.
Scandium sulfide ScS: 2 atomsScandium sulfide Sc2S3: 5 atoms
341 grams scandium (1 mole Sc/44.96 grams)(6.022 X 1023/1 mole Sc) = 4.57 X 1024 atoms of scandium =====================
The chemical formula for scandium oxide is Sc2O3. It is formed by the combination of two scandium atoms with three oxygen atoms.

One molecule of sodium hydroxide (NaOH) contains one sodium atom (Na), one oxygen atom (O), and one hydrogen atom (H), totaling three atoms.
The element with one 3d electron is manganese (Mn), which has the electron configuration [Ar] 3d^5 4s^2.
The chemical formula of potassium hydroxide is KOH.So, potassium hydroxide has 3 atoms in the formula.The dissociation equation is:KOHK+ + (OH)-
Calcium is bivalent and hydroxide is monovalent, so its formula is Ca(OH)2 => 5 atoms
Five(5) hydrogen atoms
hydroxide atoms
Barium hydroxide has five atoms in the molecule.
