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 =====================
Sodium hydroxide is NaOH and contains three atoms, one each of sodium, hydrogen and oxygen.
Lithium atoms have three electrons.

Sodium hydroxide is NaOH and contains three atoms, one each of sodium, hydrogen and oxygen.
Lithium atoms have three electrons.
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.
