How does the mass and size of an atom compare to the mass and size of the nucleus

Chemistry

Answer:

The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. ... (10-15 m is typical for the smaller nuclei; larger ones go up to about 10 times that.) Mass. Although it is very small, the nucleus is massive compared to the rest of the atom.

gavmur [86]
BiO₃⁻ → Bi³⁺
+5           +3
Balance oxidation state:
BiO₃⁻ + 2 e⁻ → Bi³⁺ 
Balancing oxygen by adding water and balance H
BiO₃⁻ + 6 H⁺ + 2 e⁻ → Bi³⁺ + 3 H₂O
balance charge:
BiO₃⁻ + 6 H⁺ + 2 e⁻ → Bi³⁺ + 3 H₂O
      + 3                               + 3
Final:

Identify which trends in the diagrams below describe atomic radius, ionization energy, electron affinity, and electronegativity.
mihalych1998 [28]

a)  figure describe ionization energy , electron affinity & electron negativity

b) figure describe Atomic Radius

c) does represent anything

Electronegativity : An atom attracted the bond pair of electrons in a covalent bond is called electronegativity of an element.       H-->Cl

Ionization energy : The amount of energy is required to remove of an electron from an isolated gas atom is called Ionization energy.   M + IP-----> M+ + e-

Electron affinity: The amount of enery is released when an electron added to an isolated atom is called electron affinity.

   X + e- ------> X- =- EA

Atomic radius ; The distance between the center of neuclies and outer most shell is called atomic radius.
