Eat at joe's! did you know that this neon sign is experiencing a change of state? when a neon sign lights up, like the one you see here, something is happening to the neon atoms inside the tube. how is this colorful sign related to kinetic energy and phase change? a) the electrical current in the tube generates the neon gas that glows in the dark. b) electrical energy excites the neon atoms. they spin faster in the tube producing electromagnetic waves that we see as colors. c) neon atoms accelerate once electrical energy is turned on to the tube. the faster the atoms move in the tube, the brighter the glow we see. d) electrical energy accelerates the electrons in the neon gas. the gas ionizes and becomes plasma, containing both positive and negative ions.

The volume of a single vanadium atom is 9.29×10-24 cm3. what is the volume of a vanadium atom in microliters?

How is the way a mixture is combined different from how a compound is combined?

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table? atom p has an estimated zeff of 7 and is therefore to the left of atom q, which has a zeff of 6. atom p has an estimated zeff of 7 and is therefore to the right of atom q, which has a zeff of 6. atom p has an estimated zeff of 5 and is therefore below atom q, which has a zeff of 4. atom p has an estimated zeff of 5 and is therefore above atom q, which has a zeff of 4.
