A. if you have a periodic table that is not color coded, describe where to look on the periodic table to find elements which have similar chemical properties.
b. explain why they have similar chemical properties.
c. name three elements that have those similarities.
If periodic table is not color coded then we should look at the group to find elements which have similar chemical properties.
For example: Elements of group 1 forms basic oxides
And elements in group has equal number of valence electrons.
Like elements of group 1 are: lithium, sodium and potassium.
2. They have close to the same number of valliance electrons
Neon Argon Krypton
When a periodic table is not color coded then we can find the elements with same chemical properties in a column.
This is because elements present in a column have same number of valence electrons and it is the valence electrons which help in determining the chemical reactivity and other properties of an element.
For example, chlorine, bromine, and iodine are all group 17 elements and they show similar chemical properties.
B) This is because their atoms have the same number of electrons in the highest occupied energy shells
C) Lithium, sodium, potassium in group 1 elements are reactive metals called the alkali metals
Reactivity depends on the number of valence electrons. Number of valence electrons the element has will determine if the element needs to gain electrons or give out electrons.
Therefore elements with same number of valence electrons will have similar chemical properties .
When you look at elements in the same group(column) they have similar chemical properties
r = ρ x length / area
ρ = r x area / length
ρ is in ohm-meters
in basic units, it is m³kg/s³a²
i think this is it.
