Answer:
Explanation:
a)
Even if a periodic table is not color coded, we can still find elements with the same chemical properties. This is easy because when we look at the group to find the elements, we see those that have similar chemical properties.
As an example, the Elements of group 1 forms basic oxides. This is a general chemical property of all group 1 elements.
b)
They have similar chemical properties because all the elements in any group has the same number of valence electrons.
c)
Lithium, Sodium and Potassium.
They're all elements of group 1, they all have 1 valence electron

When the cell has reached an appropriate size and is in a supportive environment for DNA replication, it will exit either G1 or G0 and enter the next phase of interphase called S phase. S phase, or synthesis, is the phase of the cell cycle when DNA packaged into chromosomes is replicated.
