11. elements on the periodic table are arranged by increasing (4 points) number of neutrons reactivity mass atomic number 12. protons are located (4 points) both in orbit and in the nucleus in the nucleus with electrons in orbit around the nucleus in the nucleus with neutrons 13. which of the following is not true for atoms? (4 points) they are made of protons, neutrons, and electrons. they are the building blocks of matter. they are made up of elements. they contain a nucleus. 14. which of the following is not true for atoms? (4 points) they are the smallest particle of any element. they are able to be divided by a chemical reaction. they are the building blocks of matter. they are made of protons, neutrons, and electrons. 15. cl is highly reactive. you would expect nacl to (4 points) be highly reactive take on some of the properties of cl have similar properties to cl to have completely different properties 16. as you move from left to right across the periodic table, the atomic numbers (4 points) decrease are random stay the same increase 17. an ionic compound is formed when (4 points) a metal bonds with a nonmetal a nonmetal bonds with another nonmetal three nonmetals bond together a metal bonds with another metal
