Isotopic notation of phosphorus-29 is 
Explanation:
- Isotopes are atoms with equal number of protons but different number of neutrons at its nucleus.
- The isotopic notation for any element can be written as
where X represents the chemical symbol ,A represents mass number and Z represents atomic number - The atomic number for phosphorus is 15
- Isotope's mass number for phosphorus-29 is 29
- The chemical symbol for phosphorus is P
- Hence Isotopic notation is
- Number of neutrons = 29-15 =14
- Number of protons=atomic number =15
<span>The answer is A. Copper and silver are two examples of atoms that will form a metallic bond. Pure metals in solid state form nets similar to crystals, but they are not ionic. The electrons of the valence shell are shared by all the atoms. The electrons can move freely in what is called a "sea of electrons" which is what confere metals the property of conducting electricity.</span>
M(Mn(ClO3)3)=(54.938)+(35.45x3)+(15.999x9)
