25
An atom of an element contains 20 protons, 20 neutrons and 20 electrons, This element is
An alkali Metal
26
Which two elements have the most similar chemical properties?
Which ever elements is right below the other
27
Compare the atomic radius of a sodium atom, the atomic radius of a magnesium is smaller. The radius is primarily a result of the magnesium having a
Larger nucleus charge
28
According to the periodic table which element has the smallest atomic radius?
Whichever one is closest to the top right
29
Which has the largest atomic radius?
Whichever one is closest to the bottom left
30
As the element of group 16 are considered from top to bottom on the periodic table the atom radii
Increase and the ionization decreases
31
As the elements Li to F in period 2 are considered in succession, how do the relative electronegativity and atomic radius of each successive element compare
The relative electronegativity increases and the atomic radius decreases
32
The radius of a calcium ion is smaller than the radius of a calcium atom because the calcium ion contains the same nuclear charge and
fewer electrons
33
The S2- ion differs from the S0 atom in that the S2- ion has a
larger radius and more electrons
34
More than two thirds of the elements in the periodic table are
Metals
35
``` Which element is considered malleable? Gold Radon Hydrogen Sulfur ```
Gold
36
Which element has the most pronounce metallic prop
The one closest to the bottom left
37
Which period 3 element has the least metallic characteristic
The one farthest from the bottom left
38
``` The Table below shows some properties of elements A, B, C, D Element IE EN COHAE A Low Low Low B Low Low High C High High Low D High High High IE= Ionization Energy EN= Electronegativity COHAE= Conductor of Heat and Electricity What element is most likely non-metal? ```
C
39
A non-metal could have an electronegitivity of
2.6
40
Non-metals in the solid state are poor conductors of heat and tend to
Be brittle
41
As elements are considered from top to bottom in Group 15 which sequence in properties occur
Non-metal, metalloid, metal
42
The amount of energy required to remove the most loosely bound electron from an atom in the gaseous state is called
Ionization Energy
43
The highest ionization energies are found in group what?
18

(F) or the closest one to the Noble Gases
45
Which atom will lose an electron most readily?
The ones closest to the bottom left
46
A reason why chlorine has a high ionization energy than sulfur is that chlorine has a
larger nuclear energy
47
If M represents an atom of an alkali metal, the correct formula for a compound of this atom with chlorine is
MCl
48
Which group of elements occur only as compounds in nature because they are extremely reactive
