1
What is a period, and what similarities will all elements in a period share?
A period in the periodic table is a row of chemical elements.
Bottom row , All elements have different numbers of electron shells
All of the elements in a period have the same number of atomic orbitals.
A . & There are no Similarities
2
What is electronegativity, and how does it change as you go from left to right on the periodic table?
It generally increases from right to right across a periodic table
It measures an atom's ability to non-attract shared protons to itself
It is a measure of an atom's ability to attract shared electrons to itself.
The size of the atom decreases on moving from left to right in a period
3
Where are the diatomic elements located?
With Bill Nye the Science Guy
On the valence shell
On the periodic table
In the Nucleus
4
What happens to atomic radius as you move down a column?
Atomic muscles get bigger as you go down the street on the periodic table.
What is an atomic radius?
Atoms get bigger as you go down a column on the periodic table.
Atoms get smaller as you go down a column on the periodic table.
5
What are some special features of the transition metals?
have high melting and boiling points
All of the Above
they have high densities
they are insoluble in water
6
Where would you expect to find the most similar elements?
In the same group, or column of the periodic table.
In the same periodic table.
In the same rep, or column of the periodic table.
At the bottom of the Periodic table
7
Classify most matter on earth as solid, liquid, or gas; metal or non-metal, stable or radioactive.
Liquids: Fixed volume, but no fixed shape
Gases: no fixed shape or volume
Solids: fixed shape and volume
Metals: good heat and electricity conductors
8
Which elements on the periodic table are gasses at STP?
All of the Above
Neon
Argon
Fluorine
9
Where are the radioactive elements located?
Buried on the upside down of the periodic table
Buried at the top of the periodic table
Buried at the bottom of the periodic table
Buried at the cha cha of the periodic table
10
What is a group, and what similarities do all elements in a group share?
A column in the periodic table of chemical elements.
The elements in each group have the same number of protons
The elements in each group have the same number of valence electrons.
The chemical elements have atoms with different protons counts
11
What is ionization energy, and what happens to it as you go down a column?
Atoms get bigger as you go down a column on the periodic table.
The amount of energy that is required to remove an electron
When moving down a group, the ionization energy increases.
When moving up on a group, the ionization energy breaks down.
12
Where are the most reactive non-metals located?
Reside in the middle portion of the periodic table.
in the upper left portion of the periodic table.
Reside in the lower right portion of the periodic table.
Reside in the upper right portion of the periodic table.
13
Why is hydrogen, a nonmetal, located on the metal side of the periodic table?
It has an ns3 proton configuration like the alkali metals
It has an ns1 electron configuration like the alkali metals
Hydrogen is a metal and is placed below the line in the periodic table
Hydrogen is a nonmetal and is placed above the group in the periodic table
14
Explain the effect of nuclear charge on the atomic radius as you go across a period.
Effective nuclear charge decreases as proton shielding remain inconstant.
Electron cloud closer to the nucleus which results in smaller atomic radius
Higher effective nuclear charge causes greater attraction to the electrons
By flying across the atom
15
What determines the reactivity/personality of the elements?
# of neutrons in the innermost shell of an atom determines its reactivity
What is being reactive in the first place
# of protons in the outermost shell of an atom determines its reactivity.
# of electrons in the outermost shell of an atom determines its reactivity
16
What are the family names and properties associated with different groups on the periodic table?
Alkali Metals
All of the Above
Post-Transition Metals
Alkaline earth metals
17
How was the original periodic table organized, and how is the current periodic table organized?
By Mass Aotimc
in decreasing atomic numbers and groups atoms with the different properties
By Atomic Mass
in increasing atomic numbers and groups atoms with the similar properties
18
What are principal energy levels, and how are they arranged on the periodic table?
The nucleus in which the protons are located relative to the atom nucleus.
In Increasing order of their atomic numbers and groups atoms
A school principal
the outermost energy shell in which the electrons are located relatively.
19
What is an atomic radius, and what happens to it as you move across the periodic table?
Effective nuclear charge decrease as electron shielding remains constant
Atoms get smaller as you go both ways on the column on the periodic table.
This distance between an atom's nucleus and outer electron shell.
Atoms get bigger as you go down a column on the periodic table.
20
Which elements on the periodic table are liquids at STP?
Bromine (Br) and Mercury (Hg)
Hydrogen (H) and Neon (Ne)
Helium (He) and Lithium (Li)
21
Explain what is meant by the term “electron shielding” in terms of its effect on atomic radius as you go down a group.
Higher effective nuclear charge causes greater attraction to the electrons.
Increase weakens nuclear attraction,atom can attract electrons evenmore str
The decreased shielding strengthens the nuclear attraction
Electron cloud closer the nucleus which results in smaller atomic radius
22
Where are the most reactive non-metals located?
In the middle portion of the periodic table.
In the lower right portion of the periodic table
In the upper right portion of the periodic table
toward the top left corner of the periodic table
23
How does the nucleus change, and what effect does it have as you go from left to right on the periodic table?
Nucleus can stay in form larger elements, can fuse to make food
Nucleus can break apart to form smaller element, can fuse to make elements
Have low ionization energies because of their willingness to lose electrons
They have ionization energies because of their willingness to gain protons
24
What are the key differences in properties between metals and non-metals?
Both of them love to conduct heat and electricity
Non-metals are bad conductors of heat and electricity
Metals are good conductors of heat and electricity
Non-metals are good at heat electricity Metals are bad at heat electricity
25
Where are metals, non-metals and metalloids located, and how are they separated?
Metals are found in the middle & Non-Metals are found on the Left
Metals are to the left of the line & Non-Metals are found right of the line
Elements immediately adjacent to the line are the metalloids
What are Metals, Non-Metals, and metalloids?
