Sir isaac newton lived in the 1600’s. his laws of motion and gravity were written many years ago. which of the following is true? a. newton’s laws are too old to be usable. b. newton’s laws have been disproved by modern scientists. c. newton’s laws still apply today. d. new information has made newton’s laws outdated.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.

a
