The atoms of the elements in Group 13 (IIIA), the boron group, have three valence electrons, all of which are unpaired. The atoms of the elements in Group 15 (VA), the nitrogen group, have five valence electrons, three of which are unpaired.

Do Atoms have no overall eletric charge?
Elements, as they appear on the Periodic Table, have no net charge. They all have equal numbers of protons (+) and electrons (-). HOWEVER, an atom can gain or lose electrons, which will change its charge, but, again, on the periodic table, they all have 0 charge.
Why iodine must appear in group 7 in the periodic table?
Iodine, like all group 7 elements, has 7 valence electrons.
Why do individual isotopes not appear on the periodic table?
In the periodic table only the chemical elements appear; but tables for isotopes also exist.
What are the periodic table?
Periodic table comprises of elements arranged in rows and columns.So that the elements having similar properties appear together.
How can we calculate the atomic number bet we can't see the electrons?
We don't need to. The atomic number is based on the number of protons. Since all elements as they appear in the periodic table have the same number of protons and electrons, if we know one, we know the other.

Why do elements with similar properties appear at regular intervals in the periodic tabele?
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
Why do individual isotopes not appear on the periodic table?
In the periodic table only the chemical elements appear; but tables for isotopes also exist.

Where do the elements that are good thermal and electrical conductors appear on the periodic table?
These elements are metals, to the left.
Where is the transuranium elements located on the periodic table?
Transuranium elements are elements that appear after uranium. Elements with atomic number 93 to 103, appear in the actinides whereas elements with atomic number 104 to 118 appear in the 7th period.
What is the relationship between the electron configuration of an element and the period in which that element appear in the periodic table?
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
Do the oldest know metallic elements appear at the beginning of the periodic table?
No, it is not true.

We don't need to. The atomic number is based on the number of protons. Since all elements as they appear in the periodic table have the same number of protons and electrons, if we know one, we know the other.
Why don't alkanes appear in the periodic table?
periodic table is the table of elements while alkanes are compounds of carbon and hydrogen.
What is the symbol in the periodic table for pewter?
Pewter is not an element, it is an alloy of several metals, so it does not appear on the periodic table of the elements.
