Elements in Group VIA (Group 16) have similar properties because they all have .?
* the same number of valence electrons* the same number of electrons needed to fill their octetApex :)
Why are the elements in groups 1A-8A called the representative elements?
They follow a pattern for valence electrons.
Do an elements properties change when it combines with another element?
The chemical properties of atoms are significantly changed when they form compounds. When elements combine to form compounds it is called a chemical reaction. The compound is then a collection of molecules and each molecule has in it atoms from the elements used in the formation. The atoms in the molecule are still the same atoms as one started with, but the arrangement of the electrons in the atoms has changed. It is the electronic properties of atoms and molecules that really determine the properties they have and which chemical reactions occur and which do not. The chemical properties of an atom or molecule are determined by the arrangement of the electrons of that atom or molecule. Once atoms have gone through a chemical reaction, the electronic structure is changed. The atoms are the same identity, but the properties of the atoms have been changed by the chemical reaction.
What are the two especially important properties that Dmitri mendeleev noted about the elements?
he noted gaps in the table, and predicted that as of yet unknown elements existed with properties appropriate to fill those gaps.
Elements in Group IIA (also known as Group 2 or the alkaline earth metals) have similar properties because they all have the same number of .?
b. valence electrons d. electrons needed to fill their octet

Is it correct to write - This issues with the approval of XYZ?
That is a simply awful construction. Some revisions: This <fill in the blank> has been approved by XYZ. This <fill in the blank> has been authorized by XYZ. This <fill in the blank> has been issued under the authority of XYZ. This <fill in the blank> is issued and authorized by XYZ. Or perhaps you meant: Pending the approval of XYZ, this <fill in the blank> will be issued.

Why was the pattern that Newlands developed called the 'law of octaves'?
his tables contained gaps that elements with particular properties should fill.

What did the gaps on Mendeleev's tabel represent?
He predicted that elements with the predicted properties would be discovered to fill in these gaps.

What Mendeleev's prediction?
Professor Dmitri Mendeleev published the first Periodic Table of chemical elements in 1869 based on properties which appeared with regularity. He noted gaps in the table, and predicted that as-of-yet unknown elements existed with properties appropriate to fill those gaps.
