Use the Periodic Table of Elements to answer the following
questions:
1.
Find the protons = ___, neutrons =___, and
electrons =___ for Lithium (Li)
2.
Find the protons = ___, neutrons =___, and
electrons =___ for Beryllium (Be)
3.
Find the protons = ___, neutrons =___, and
electrons =___ for Boron (B)
4.
Find the protons = ___, neutrons =___, and
electrons =___ for Neon (Ne)
5.
The atomic mass of Silicon (Si) is approximately
_____ amu
6.
Uranium is a highly radioactive element composed
of ________ neutrons.
7.
In the first period or row list all the chemical
symbols.
8.
Use two different symbols, one more than once, to
create the chemical formula for water.
9.
Write a chemical equation for the formation of
water. Remember the left side of
the arrow is the reactants and the right side is the products.
10.
The first column is known as the _________ metals
and they _______ one electron because they are “givers”.
11.
The second column is known as the alkaline earth
___________ and they __________ electrons because they are “givers” also.
12.
The 18th column is known as the
________ gases, they are happy by themselves so they don’t ______ or ______
electrons.
13.
The Halogens are in column _____ and they are
“takers” so they _____ one electron.
14.
Element “X” has 27 protons, 28 neutrons, and 28
electrons. Element “Z” has 13
protons, 13 neutrons, and 14 electrons.
Are these atoms stable?
Will these atoms hook up (attract) or will they just talk behind each other’s
backs and get mad each other (repel)?
15.
As you reference the elements from Sodium (Na) to
Argon (Ar) what happens to the number of protons?
What happens to the atomic mass?
16.
Fluorine has always been very jealous of Carbon’s
popularity; explain why carbon has so many friends (bonds available).
Why is Fluorine left with no one to dance with at the party?
17.
The electron shells fill the first shell with
____ electrons and the second with ___.
The outer electrons are called _____________ electrons.
18.
Why are the outer most electrons important?
Explain
19.
From Lithium to Argon these elements are
constantly trying to fill their outer shell with _____ electrons.
20.
Sketch Sodium and Chlorine below.
Include protons, neutrons, and electrons.
Assuming the two atoms are stable what will happen if they come close
enough together to touch? Explain.
21.
Column 1 has how many valence electrons?_____,
column 2 = ______ve-, column 13 = ____,
column 16 = ____, and column 18 = ______
22.
So an atom with 18 electrons will have how many
