How does a geiger counter measure radiation levels? a) radiation is absorbed by gas atoms, which undergo phosphorescence and emit a different radiationb) radiation is absorbed by gas atoms, which undergo nuclear reactions and emit a different radiationc) radiation knocks neutrons out of gas atoms, which causes the gas atoms to become unstabled) radiation knocks electrons out of gas atoms, which allows the gas to conduct an electric current

Compare and contrast the bohr model and the electron cloud models of the atom.

Why is it possible for different microorganisms to extract energy not only from carbohydrates and other biological molecules but from a large variety of substances?

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
