switched some of the elements so that the elements within groups have similar properties

was responsible for adjusting the table according to atomic number
(1900’s)

Question 21

as you go from left the right, atomic radius…

Answer 21

decreases

Question 22

as the atom gets bigger, the atomic radius

Answer 22

increases

Question 23

as you go from left to right, the _______ increase

Answer 23

protons

Question 24

in a period, as the number of protons (nuclear charge) increase, what happens to the electrons?

Answer 24

the attraction to the electrons increases as well, so the size of the atom gets smaller

Question 25

ionization energy

Answer 25

energy required to remove the most loosely held electron (valence electrons)

Question 26

as the atom gets smaller, the ionization energy…

Answer 26

gets higher (harder to remove valence electron)

Question 27

electronegativity

Answer 27

attraction of the atom to its electrons

Question 28

most active metal

Answer 28

Fr - Francium because it has the least amount of pull to the nucleus

Question 29

most active nonmetal

Answer 29

F - Fluorine because it has the greatest pull to the nucleus

Question 30

metallic activity decreases going..

Answer 30

across the periodic table stairs

Question 31

metallic energy increases going…

Answer 31

down the periodic table stairs

Question 32

activity of an element depends on

Answer 32

how they form an ion

Question 33

all metals: the atomic radius is _______ than its ionic radius

Answer 33

larger

Question 34

all nonmetals: the atomic radius is ________ than its ionic radius

Answer 34

smaller

Question 35

within a period, as atomic number increases

Answer 35

atomic radius decreases ionization energy increases electronegativity increases metallic character decreases

Question 36

within a group, as atomic number increases

Answer 36

atomic radius increases ionization energy decreases electronegativity decreases metallic character increases

Question 37

to the left of the staircase is to the right of the staircase is

Answer 37

metals nonmetals

Question 38

what do all elements in the same row (periods) have in common?

Answer 38

the same number of rings

Question 39
