NaOH --------- This is sodium in ionic form, Na +, and the hydroxide polyatomic ion, OH -.
What is 'oh' ? If you mean 'OH' , This is the hydroxide anion and is correctly written as 'OH^-' , because it is a charged species. The hydroxide anion is composed of 1 x oxygen and 1 x hydrogen atoms and 1 x excess electron. You will find Hydrogen (H) and Oxygen(O) separately on the Periodic Table. Also when writing up chemical symbols, please follow the following rules ; - #1 Single letter elements ALWAYS have a capital letter . #2 Two letter elements have a capital to start and ALWAYS a small case letter as the second letter. These are the international standard, followed world-wide. Oh!!!! 'oh' does not mean anything chemically.
Ci means chlorine in the periodic table
Er means erbium in the periodic table. It belongs to lanthanide series.
Mo stands for Molybednium in the periodic table. It is placed in group-6.
OH is not an element. It consists of two separate elements: hydrogen (H) and oxygen (O).
Hydroxide (Hydrogen and Oxygen)
NaOH --------- This is sodium in ionic form, Na +, and the hydroxide polyatomic ion, OH -.
O is oxygen and H is hydrogen, but HO is nothing, it's only ever 1 capital (and sometimes a lowercase letter)
Ai is not an element on the periodic table
Ni is the symbol for Nickel in the Periodic Table.

'OH' does not appear in the periodic table. 'OH' is more correctly the hydroxide anion. and should be written as 'OH^-'. The 'O' is the elememnt Oxygen , which is No. 8 (Atomic No.) in the periodic table. and 'H' is the element Hydrogen, which is No.1 (Atomic No.) in periodic table. The hydroxide anion forms alkalis with metal e.g. sodium or potassium and their formulas are NaOH and KOH respectively. In Organic chemistry the 'OH' functional group forms alcohols, e.g. Ethanol (Ethyl Alcohol) and its formula is CH3CH2OH. This is the alcohol that is in beers wines and spirits.
B is the symbol for boron which is an element on the periodic table
On the periodic table Ni represents the element Nickel.
Ci means chlorine in the periodic table
Iodine
