Hydrogen forms compounds with elements having atomic number '9,11,12' and '17 .' What are their chemical formulae?

elements with atomic no '9,17,35,53' and 85 are all

Draw and exhibit the Bohr mọdel of elements having atomic number 1 to 10

The element with atomic number 9 can exhibit oxidation state of:

Write all possible oxidation states of an element having atomic number 25

The element Cu with atomic number 29 undergoes chemical reaction to form an ion with oxidation number +2. a) Write down the subshell electronic configuration of this ion? b) Can this element show variable valency? Why? c) Write down the chemical formula of one compound formed when this elemrnt reacts with chlorine (Cl_17)

The element Cu with atomic number 29 undergoes chemcial reaction to formation with oxidation number +2: Write downthe chemical formula of one compound formed when this element re-acts with chlorine ("17CI) .

The combination of elements of form compounds is governed by the laws of chemical combination. Hydrogen combines with oxygen to form compounds, namely water and hydroge peroxide. What is meant by 'limiting reagent' in a chemical reaction?
