Answer:

Bohr model proved that electrons orbit the nucleus in distinct energy levels.

Explanation:

Rutherford's atomic model proved that the nucleus of the atom is positively charged and the electrons are placed randomly outside the nucleus. But Bohr's atomic orbital explained the spectral lines of different elements by theorizing that the electrons orbit the nucleus in distinct orbits or energy levels. Upon accepting energy electrons jump from lower to higher energy levels and release energy when they return to a lower energy level from a higher energy level.

Wavelength decreases as frequency increases.
Imagine a heart rate graph.  As the heart beats faster, frequency increases and the time between heartbeats decreases (wavelength).

A. For a two-component alloy, derive the equations that convert the weight percent to atomic percent (for a two-element alloy).
atroni [7]

Answer:

a. wt% A / Atomic Mass A / (wt% A / Atomic Mass A + wt% B / Atomic Mass B).

b. 11.74%

Explanation:

a. Weight percent is the mass of an element in 100g of the alloy. Atomic percent could be taken as the ratio between moles of an element and the total moles of the alloy.

Assuming a basis of 100g, the moles of A and B (The two elements in the alloy), are:

<em>Moles A:</em>

wt% A / Atomic Mass A

<em>Moles B:</em>

wt% B / Atomic Mass B

<em />

And atomic percent of A is:

<h3>wt% A / Atomic Mass A / (wt% A / Atomic Mass A + wt% B / Atomic Mass B)</h3><h3 />

b. Atomic fraction of Cu in the alloy is (Molar mass Cu: 63.55g/mol; Molar mass Ag: 107.87g/mol):

7.25wt% / 63.55g/mol / (7.25wt% / 63.55g/mol + 92.5wt% / 107.87g/mol)

Atomic fraction Cu = 0.1174 = 11.74%
