Question

#1: What is the ionization energy of an element?

A. the energy needed to move an electron from an inner orbital to an outer orbital

B. the ability of an atom to attract new electrons

C. the energy needed to remove an electron from an atom

D, the energy needed to turn an atom into an anion

***my answer: C

not too sure tho.. is it right?

Answer 1

#2: What happens to the electronegativity of elements as you move from bottom left to upper right across the periodic table?

A. Electronegativity decreases.

B. Electronegativity does not change.

C. Electronegativity increases.

D. There are no real patterns concerning changes in electronegativity.

**My answer: C. it increases

is that right?

Answer 2

from this page

http://www.shodor.org/chemviz/ionization/students/background.html

"The ionization energy is the amount of energy it takes to detach one electron from a neutral atom"

Answer 3

so C looks good

Answer 4

kk what about #2?

Answer 5

Ionization energy increases as you move across the table, and decreases as you move down the table.

Answer 6

so my answer to #2 is C. it increases??

my answer was right??

Answer 7

and #3: Which of the following cannot be deduced from the periodic table?

A. many physical properties of elements

B. many chemical properties of elements

C. time of discovery of elements

D. trends in electronegativity of atoms

**my answer: C. time of discovery

is that right??

Answer 8

2C looks good

Answer 9

kk and #3? :)

Answer 10

and 3C is def the answer (since there are no timestamps or historical references on the chart)

Answer 11
