22. Hay is used with definite articles like el, la, los, and las.

Use image for the following question: 

The following data may be useful for the next question.  Ionization Number Energy (kJ/mol) 1st 1,314 2nd 3,388 3rd 5,300 4th 7,469 5th 10,990 6th 13,327 7th 71,330 8th 84,078

Which of the following model would most likely represent NaCl? 

Use for the next question. 

Which of the following has a larger atomic radius? P S Because… the valence electrons are further from the nucleus the valence electrons experience a lower effective nuclear charge sulfur has more total electrons than phosphorous

A wavelength of 650 nm is altered to 550 nm, what changes would be impacted? The frequency of the light. The number of photons of visible light. The energy of the light. The amplitude of the wave of visible light.  

Use the data table in the previous question for the first eight ionization energies found for a particular element shown in the previous question to predict and explain which element would you expect to show this trend in successive ionization energies? 1.   F 2. O Because Core electrons are more strongly attracted to the nucleus than valence electrons. Valence electrons release more energy when they are removed from the atom.

Orange light has a wavelength of 600 nm. What is the energy of one photon of orange light?

Why does the potential energy increase as two xenon atoms move extremely close together?
