The maximum number of VEs is

8 in the outermost energy level (except for H and He)

Elements in the same column of the PT have the same chemical properties because they have

the same number of valence electrons

Valence electrons ...

are in the outermost and highest energy level

there are the same number of protons and electrons

The mass of a neutron

is about the same as the mass of a proton, or 1 amu

You definitely need to know how to draw Electron Configuration drawings for this quiz

Of course, that goes without saying

H and He have less than 8 VE's because

They have only 1 and 2 protons, respectively

Elements with the same number of VEs have chemical properties that are

very similar, because they have the same number of VE's

The charge of a neutron

is cero, null, zilch, zero, 0.0000

is 1 amu, the same as a neutron

always equals the number of protons

Two different isotopes of the same element have

the same # of protons but different # of neutrons

Questions 38

Answers

1
Each column of the PT is called a
group
period
community
cluster
2
An Atom of Hydrogen has an atomic number of 1 and an atomic mass is 1.008, so it usually has
2.008 neutrons
no neutrons at all
1.008 neutrons
an infinite number of neutrons
3
The nucleus of an atom consists of
neutrons and protons
electrons and neutrons
a cloudlike mass of quazars
protons, electrons and neutrons
4
An Aluminum atom has an atomic number of 13 and an atomic mass is 26.982, so it has an avg of
approx 12 neutrons
approx 13 neutrons
approx 14 neutrons
approx 27 neutrons
5
All of the elements in Period 3 of the PT have
exactly 3 valence electrons
3 electrons in their innermost electron shell
none of the above
3 electron shells
6
Each row of the PT is called a
comma
semicolon
period
exclamation
7
The maximum number of VEs is
two
usually 1
8 in the outermost energy level (except for H and He)
8 for every atom
8
Elements in the same column of the PT have the same chemical properties because they have
names that start or end with the same letter
the same number of valence electrons
the same number of energy levels (shells)
the same atomic mass
9
Valence electrons ...
are in the outermost and highest energy level
are in the lowest energy
are the only positively charged electrons
are really not that important
10
The symbol for a proton is
p0
p-
p+
p?
11
Hello - I am an atom in Group 15. That means I have
6 VE's
7 VE's
5 VE's
4 VEs
12
In a neutral atom
The total charge is zero, because neutrons cancel protons
there are the same number of protons and electrons
The total charge equals the atomic mass
there are the same number of protons and neutrons
13
The number of electrons in a neutral atom
equals the number of neutrons
equals the number of protons
equals the number of shells
is always exactly half of the atomic mass
14
A Lewis Dot Diagram
shows electrons but not protons
looks similar for every element in a given group
only shows the number of VE's
all of the above
15
An Atom of Boron has an atomic number of 5 and an atomic mass is 10.811, so it has an avg of
approx 11 neutrons
approx 5 neutrons
approx 6 neutrons
approx 10 neutrons
16
Howdy! I am an electron in Group 16, so I have
5 VE's
7 VE's
8 VE's
6 VE's
17
Another accepted name for electron "shells" is
rings
circles
orbitals
orbits
18
An Atom of Argon has an atomic number of 18 and an atomic mass is 39.948, so it has an avg of
approx 21 neutrons
approx 22 neutrons
approx 21 neutrons
approx 40 neutrons
19
The charge of a proton
is when it rushes forward almost frantically
is equal to +1
is the opposite of the retreat of an electron
is 1 amu
20
The mass of a neutron
is much smaller than the mass of electrons
is about the same as the mass of a proton, or 1 amu
is about twice the mass of a proton
is approx the same as the mass of an electron
21
You definitely need to know how to draw Electron Configuration drawings for this quiz
Most likely
probably not
Of course, that goes without saying
It's 50/50
22
H and He have less than 8 VE's because
no one knows - it's a true mystery!
they start with H
They have only 1 and 2 protons, respectively
they have many more protons than 8
23
What is the symbol for an electron
En
e-
E
e+
24
Calcium (Ca) has an atomic number of 20. It's electron configuration is
8, 8, 2, 2
2, 8, 2, 8
???? (I need to study this)
2, 8, 8, 2
25
Elements with the same number of VEs have chemical properties that are
very similar, because they have the same number of VE's
wrong answer
wrong answer
wrong answer
26
Elements in the same group have
the same number of shells
the same number of VE's
the same number of protons
the same number of neutrons
27

Predicament
Rice Card
Pre Corp
Periodic
28
Elements in a column of the PT have
the same number of neutrons
the same number of electrons
the same number of protons
none of the above
29
"Hey - I'm an atom in Group 19". This means that I have
2 valence electrons
1 valence electron
forgotten what group I am in
8 valence electrons
30

Bohr's Model says...
None of the above
Electrons travel in clouds around a nucleus
It's impossible to know how many electrons are in an atom
Protons travel in shells (energy levels)
