Ions can be atomic or molecular. If an atom contains either positive or negative charge it said to be atomic cation or atomic anion.
When a molecule carry positive or negative charge it is called as polyatomic cation or polyatomic anion. Generally charged or ionized molecules are called as polyatomic ions.
In given question Fe(HCO₃)₃ ionizes as follow,
Fe(HCO₃)₃ → Fe³⁺ + 3 HCO₃⁻
The Ions produced are Fe³⁺ and HCO₃⁻. Fe³⁺ is said to be atomic (Ferric) ion and HCO₃⁻ (Bicarbonate) is polyatomic ion or molecular ion.
Answer:
Left
Explanation:
Metals are located on the left of the periodic table, and nonmetals are located on the upper right. They are separated by a diagonal band of semimetals.
No. It appears behind the equation
all of the above.
The properties of water are:
1) polar molecules
2) regulates temperature
3) universal solvent
4) high surface tension
5) can exist in all three stages of matter
All of the group iia metals (the column with Be, Mg, Ca, etc) have an outermost s suborbital with 2 electrons
