IsotopesIons Periodic Table Periodic Law Prot.Neut. And Elect. Back to Home

100 Two atoms that are identical except for the number of neutrons is called? What is an isotope? Click here for answer back

200 What is the difference between C-12 and C-14? back Click here for answer C-12 has 6 protons and 6 neutrons C-14 has 6 protons and 8 neutrons

300 Are atoms a and b isotopes? Atom a = 3 p, 3 e, 3 n Atom b = 3 p, 4 e, 3 n back Click here for answer No they have the same number of protons and neutrons, they differ in the # of electrons so they are ions

400 Which two atoms are isotopes? A = 8 p, 8 n, 8 e B = 7 p, 7 n, 8 e C = 8 p, 8n, 7 e D = 8 p, 9n, 8 e back Click here for answer A & C because they have the same # protons and electrons, but a diff. # neutrons

100 An atom that becomes charged from gaining or losing electrons is called __________? back Click here for answer What is an ion?

200 An atom that loses an electron is positive or negative and is called what back Click here for answer What is (positive) and (cation)?

300 If you have 3 p, 4 n, 3 e; what is the overall charge of the atom? Is it an anion, cation, or neither? back Click here for answer It has +3 protons and -3 electrons so the overall charge is zero and it is neither a cation or an anion

400 Which example will give a negative anion charge? A = 2 p, 2 n, 3 e B = 2 p 3 n, 2 e C = 2 p, 1n, 1 e back Click here for answer A. Because +2p and -3e = -1

100 This group is the most reactive metals on the periodic table and found in group 1 back Click here for answer What is alkali metals?

200 These elements are the least reactive on the periodic table and found in group 18 back Click here for answer What are noble gases?

300 What is the name for the elements in yellow, green, and blue? back Click here for answer What are metals, metalloids, non metals?

400 Fluorine, chlorine and bromine are found in what group? back Click here for answer halogens

100 Why is the periodic table called “periodic”? back Click here for answer Because it has repeating patterns that exist over and over again

200 Atoms on the periodic table are arranged according to what? back Click here for answer What is the atomic number?

300 Which elements are more similar? Li and F OR Li and Be? back Click here for answer All three elements are found in the same period and the properties vary in a period, but Li and Be are closer than Li and F therefore (Li and Be) are more similar

400 Would Ar and Xe share similar properties? back Click here for answer Yes, because they are in the same group or family (vertical column) and groups/families share similar properties

100 What does the atomic mass = ? back Click here for answer Protons + neutrons

200 What does the atomic # =? back Click here for answer The # of protons and electrons

300 If an atom has 18 protons and an atomic mass of 48, how many neutrons are there? back Click here for answer 48 – 18 = 20 neutrons

If an atom has 11 electrons and 13 neutrons what is the atomic # and atomic mass? back Click here for answer Atomic # = 13 Atomic mass = = 24
