Answer:

(a) 11000nm

(b) 9.7 * 10^14 Hz

Explanation:

Using velocity = frequency * wavelength

wavelength =  \frac{3.0 \times  {10}^{8} }{2.7 \times  {10}^{13} }  \\  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: = 1.1 \times  {10}^{ - 5} m \\   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: = 11000nm \\  \\ frequency =  \frac{3.0 \times  {10}^{8} }{310 \times  {10}^{ - 9} }  \\   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: = 9.7 \times  {10}^{14} hz

When compounds form, which of the following statements is true about the elements that form them?
Greeley [361]

Answer:

C. Their properties change completely.

Explanation:

The electron configurations of the elements show a periodic variation with increasing atomic number. Consequently, there are also periodic variations in physical and chemical behavior.  

When atoms interact to form a chemical bond, they combine in order to <u>achieve a more stable electron configuration.</u> As a consequence, the compounds formed exhibit completely different properties.

For example, when solid magnesium burns in air, it forms both magnesium oxide and magnesium nitride, which are gases.
