Ah2 molecule can be approximated by a simple harmonic oscillator having a spring constant k = 1.1 ✕ 103 n/m. (a) how many different energy transitions are possible when the h2 molecule decays from the third excited state down to the ground state? 3 correct: your answer is correct. (b) find the photon energies produced in these transitions and their wavelengths. enter 0 in any unused boxes.

the answer for sodium is 0.186

the answer for rubidium is 0.251

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
