Which is the lightest element in group 1A?
Hydrogen, which is properly a member of the periodic column. If the properties of hydrogen are considered too little like those of the other elements in the this column, the alkali metals, so that only the latter are considered members of column IA, then the answer would be lithium.
What is the seventh column called on the periodic table?
Groups Or Families
How are the elements arranged horizontally on the periodic table?
The period number of an element in the Periodic Table is the number of the highest electron shell that is occupied in the ground state of the element, and the column number, if the number has only one digit, or the last digit of the column number, if the number has two digits, is the number of valence electrons in the element, except for columns 8, 9, and 10. (For the elements in columns 3 through 11, the nominal number of valence electrons may or may not correspond to the most usual number of electrons donated, accepted, or shared in bond formation by an atom of the element.) Each element is distinguished by having one more proton than the element to its immediate left in a row, or one more proton than the element at the far right of the preceding row if the element is in column 1 and therefore has no element to its immediate left. Hydrogen is in column 1 and the only other element in the first period, helium, is in column 18. In the next two periods, columns 3 through 12 are skipped in filling the table, and in the sixth and seventh periods, column 3 is expanded into a separate row of fourteen elements at the bottom of the main table before another atom is put into column 4.
What element is not a transition element?
any in column 1a, 2a, 3a-8a
In Mendeleevs periodic table elements in each column had similar?
That some had the same among of Protons and Neutrons. That each coumn had a preiod!

How are the elements arrange horizontally and vertically on the period table?
The period number of an element in the Periodic Table is the number of the highest electron shell that is occupied in the ground state of the element, and the column number, if the number has only one digit, or the last digit of the column number, if the number has two digits, is the number of valence electrons in the element, except for columns 8, 9, and 10. (For the elements in columns 3 through 11, the nominal number of valence electrons may or may not correspond to the most usual number of electrons donated, accepted, or shared in bond formation by an atom of the element.)
