The ""size"" of an atom is sometimes considered to be measured by the radius of the sphere that contains 90% of the charge densi

ty of the electrons in the outermost occupied orbital. Calculate the ""size"" of a hydrogen atom in its ground state according to this definition. Go on to explore how the ""size"" varies as the definition is changed to other percentages and plot your conclusion.

Answer:

Is about 0.53 angstroms

Explanation:

The "size" of an atom in this definition is related with the nucleus size plus the cloud of electrons that surround the nucleus, in this case, since the Hydrogen in its basic state has only one electron, practically the size of the nucleus is the size of the atom, that is 0.53 angstroms or 5.3 x 10 -11 meters.

Hope this info is useful.

Could someone explain how they got this answer, explain step by step plz
gulaghasi [49]

Answer:

6.018 amu

Explanation:

Let 6–Li be isotope A.

Let 7–Li be isotope B.

Let the abundance of 6–Li be A%

Let the abundance of 7–Li be B%

The following data were obtained from the question:

Atomic mass of isotope A (6–Li) =.?

Atomic mass of isotope B (7–Li ) = 7.015 amu.

Abundance of 7–Li (B%) = 92.58%

Abundance of 6–Li (A%) = 100 – B% = 100 – 92.58 = 7.42%

Atomic mass of Lithium = 6.941amu

The atomic mass of isotope A (6–Li) can be obtained as follow:

Atomic mass = [(Mass of A x A%)/100] + [(Mass of B x B%)/100]

6.941 = [(mass of A x 7.42)/100] + [(7.015x92.58)/100]

6.941 = [(mass of A x 7.42)/100] + 6.494487

(mass of A x 7.42)/100 = 6.941 – 6.494487

(mass of A x 7.42)/100 = 0.446513

Mass of A x 7.42 = 100 x 0.446513

Mass of A x 7.42 = 44.6513

Divide both side by 7.42

Mass of A = 44.6513 / 7.42

Mass of A = 6.018 amu

Therefore, the mass of 6–Li is 6.018 amu
