The energy required to dislodge electrons from rubidium metal via the photoelectric effect is 218 kJ/mol . What wavelength (in nm) of light has sufficient energy per photon to dislodge an electron from the surface of rubidium

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

mark brainliest and have a great day!

the dissolution of polymer can be thermodynamically described in 2 steps.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
