Unit 3: electron configuration and periodic trends

what is the blue and red light wavelengths?

• 400nm-450nm

• 350nm-750nm

• 400nm-500nm

• 400nm-750nm

E.N down a group decreases due to ____, while it increases going across a period due to smaller atomic size.

E.N goes up to ___ and it's unit is ___.

how do you convert nm to M?

• 1nm=1 x 10^-9

• 2*300

• 200-9000+7

• 4050/30+27

What is the speed of all E.M. radiation

How do you find the speed of light?

• c=v x h

• v=c x n

What does I. E. stand for?

• incognito examples

• Interchangeable electrons

• ionization energy

What are isoelectronic series?

• Groups of ions with same # of e-

• electrified neutrons

• Rutherford's display board (1911)

Answer explanation

For ex. Ne would have 10 e-, ions would be F-1 (as it gains an ion) because it had 9, but gained 1, or it can lose an e- like Na-1

what is the name of this model?

• ring model

• Chlorine

• Bohr model

• planetary model

The energy of electrons is ____, and can only be released in ____ amounts

• qualified, numbers

• small, individual

• Quantized, specific
