What do you notice about the number of electrons in each valence shell of noble gases?
All the noble gases have 8 electrons in their valence shell except helium which have 2 electrons in its valence shell.
What do you notice in the number of valence electrons of metal?
The ability of an atom to loss this number of electrons.
What do you notice about the number of valence electrons as you move from left to right across a row or period?
The number of valence electrons increases from left to right across a period.
What do you notice about the number valence electrons?
left to right across on a row or a periodic table
What do you notice with the number of valence electrons?
The number of valence electrons determine the chemical properties of a particular element. For example, elements in group 1 tend to donate its valence electron away to produce its stable +1 ion. It also explains the formation of -1 ions from group 17 elements (halogens).

What do you notice about location of these elements?
They have the same number of valence electrons
What do you notice about the number of valence electrons as you move from left to right across a row or period?
The number of valence electrons increases from left to right across a period.
What do metals do with electrons?
Metals are elements belonging to first , second or third group. They have one ,two or three valence electrons (electrons present in the last orbit of an atom). They lose this electrons to gain stability as they are highly unstable and by doing so they react . NOTICE: An atom can only lose the electron if an atom of other element is ready to take it.

What do you notice about the number of valence electrons as you move down or up a group or column in the Periodic Table?
The number of Valence electrons of an element is the same number as the element's group number. E.g. Hydrogen is in Group 1. Therefore it has 1 valence electron. Another e.g. Oxygen is in Group 6. Therefore it has 6 valence electrons.
Do metals lose or gain electrons in a chemical reaction?
Metals will lose electrons, most of the time. If you look at the first group on the periodic table, you will notice that these metals have one valence electron (Li, Na, K etc.). These are known to readily form ionic bonds with the halogens. For example Na and Cl form salt NaCl because the Cl strips the Na of it's valence electron leaving Na with a positive charge and Cl with a negative charge. Because of the differences in charges, they attract each other and form an ionic bond.

What do you notice about the number of electrons in each valence shell of noble gasses?
You see that there are 8 electrons, which means that the shell is full. Thus, you observe that nobly gases rarely bond.
What do yo notice about the location of the elements in each family?
well its takes for ever to figure out
What do you notice about the boiling points as you move from left to right across the periodic table?
The trend of boiling points across a period in the periodic table should decrease from metals to nonmetals. The trend becomes more complicated between metals, the boiling point of metals tends to increase across a period.
