The alkali metal family of elements includes Li, Na, K, and Rb. These elements tend to easily form compounds with the halogens F, CI, Br, and
1. Which explains why they form compounds so easily?
A-They have one electron in their outer orbital which they readily lose.
B-They have the same electron configuration as the halogens.
C-They have seven electrons in their outer orbital which they readily lose
D-They have one electron in their outer orbital which attracts the protons in the
halogen atoms.

During physical science, ms. greene challenged her students to produce an energy transformation. james and jill wrapped a 4-inch nail with a coil of fifty turns of wire. they connected one end of the coil to one terminal of a knife switch. they connected the other terminal of the knife switch to the battery. finally, they connected the end of the coil to the other terminal of the battery. james held the tip of a 1-inch nail near the flat end of the 4-inch nail. jill closed the knife switch quickly and then opened it. the 1-inch nail was pulled toward the 4-inch nail. what is the best explanation of why the nail moved? a) electrical energy was converted to mechanical energy in the 1-inch nail. b) the 4-inch nail became an electromagnet and the magnetic force attracted the 1-inch nail. c) the electric current in the 4-inch nail was converted to mechanical energy in the 1-inch nail. d) the 4-inch nail had a positive charge and the 1-inch nail had a negative charge. opposites attracted.
