Chemistry Pretest

How is the periodic table of elements arranged?

The atomic number gives us

• protons

• electrons

• mass

• neutrons

• nucleus

Match the following

• where protons & neutrons are found and largest mass

• neutron

• lives in the nucleus & positively charge

• nucleus

• lives in the last ring & negatively charge

• proton

• lives in the nucleus & no charge

• valence electron

• lives in the cloud & negatively charge

• electron

Label the metals, nonmetals and metalloids

a

b

c

d

metals

metals

nonmetals

metalloids

Match the following

• generally shiny, malleable, ductile, and good conductors of heat and electricity

• nonmetals

• the horizontal rows of elements on the Periodic Table

• period

• vertical columns on the Periodic Table that contain elements with similar properties

• groups/family

• characteristics of both metals and nonmetals

• metalloids

• generally dull, brittle, and poor conductors of heat and electricity

• metals

Describe TWO things that the groups/families lets us know about the elements.

How many periods does the periodic table have AND what do each period tell us about the elements?

Valence electrons live in the ​ (a)   ring of the atomic structure. It tells us how ​ (b)   the elements are. Group 1 are the ​ (c)   whereas group 18 are the ​ (d)  

• outermost
• reactive
• most reactive
• least reactive
• innermost
