What is the element which belongs to the third group and third period?
The element belonging to the third group and third period is aluminum (Al). It has an atomic number of 13.
This element has an atomic number lower than that of aluminum and one less valence election than the group 16 elements?
The element with an atomic number lower than aluminum is silicon, which has an atomic number of 14. Group 16 elements, like oxygen and sulfur, have 6 valence electrons, whereas silicon has 4 valence electrons.
What element has an atomic number lower than that of aluminum less valence electron than the the group 16 elements?
Nitrogen

Boron is the element. Its symbol is B.
Has the lowest atomic number in Group 2?
Berylium is a non metal element. Atomic number of it is 4.
What element does aluminum belongs to?
Aluminum (or aluminium) is an element. It is atomic number 13, and has an atomic weight of 26.981. It is considered one of the "poor metals".
Consider the group 1A element sodium (atomic number 11) the group 3A element aluminum (atomic number 13) and the group 7A element chlorine (atomic number 17). These elements are in period 3. How are?
This is a consequence of the law of periodicity of chemical elements.

What element is found in group 3A and period 3?
It is indium(In) which is in 5th period in group IIIA (or group 13).
How many protons does the element have in group 13 and the 3rd period?
13 protons an easy way to remember what number of protons an element has is APES. A-atomic number, P-protons, E-electrons, S-same, so the atomic number and the numbers of protons and electrons are the same number
What element has an atomic number lower that that of aluminum and one less valence electrons than the group 16 elements?
Nitrogen
