Sagot :
Q1. Where can you find metals, non-metals, and noble gases in the periodic table of elements?
Metals can be found on the far left side of the table, the non-metals in the right, and also the noble-gases which are non-metals that are found in the far right side of the table.
Q2. Which number tells you the number of valence electron?
The group number above the columns may or can tell that number of valence electron in an atom.
Q3. What do you notice in the number of valence electron of metals, non-metals, and noble-gases?
Metals, on the right side of the table (some are under, these are the actinides and lanthanides, have least valence electron among all other types of elements, it is because the closer the group or the element to the left side, the lesser its valence electron.
Non-metals, on the left side of the table have greater valence electrons than metals, because like I said, the closer the group or the element to the right side, the greater its valence electron.
Noble-gases, on the far left side or the most left side of the table, have the greatest valence electron of all.
Q4.
A. What kind of element has less than four valence electrons?
As we can see, metals do have less than four valence electron, because metals do have lesser valence electrons than non-metals, and metals are found in the left side of the table.
B. What kind of element has more than four valence electrons?
As we can see, non-metals do have more than four valence electron, because non-metals do have greater valence electrons than metals, and non-metals are found in the right side of the table.
C. What kind of element has low electronegativity?
Electronegativity increases from the left side of the table to the right side. So definitely, metals do have low electronegativity, and the elements in the first group or alkali metals have the lowest electronegativity.
D. What kind of element has high electronegativity?
Electronegativity decreases from the right side of the table to the right side. So definitely, non-metals do have high electronegativity, and the elements in the last group or the noble gases have the highest electronegativity.
E. What kind of element has low ionization energy?
It is as same as the electronegativity, like in electronegativity of the elements, ionization energy increases from the left side to the right side. So definitely, we have metals for the answer, and also same as the electronegativity, alkali metals have the lowest ionization energy.
F. What kind of element has high ionization energy?
It is the same as the electronegativity, like in electronegativity of the elements, ionization energy decreases from the right side to the left side. So definitely, we have non-metals for the answer, and also same as the electronegativity, noble gases have the highest ionization energy.
