What major change occurs as you move from left to right across periodic table?
the atoms of the element are less reactive and smaller. they are smaller because of the larger amount of valence electrons compacting the atom.What_moves_left_to_right_on_the_periodic_table
Which synthetic polymer get harder as the number of carbon atoms in the polymer chain increase?
Polyethylene gets harder as the number of carbon atoms increases.
When the elements on the periodic table are arranged by increasung atomic number the atomic mass generally increases as the atomic number increases. for some elements however the atomic mass of the el?
It is difficult to be sure what the question is about because it has been truncated.However, it is true that the atomic mass (or standard atomic weights) increases with atomin number. There are, of course, isotopes of elements with a low atomic number which are heavier than atoms of higher atomic number. But there are some examples where the average mass is not in the expected sequence.
Form a atomic number of 15 atoms?
Atomic number is the number of protons in an atom, not the number of atoms. The element with the atomic number 15 is phosphorus.
Nuclear charge increases across a period atoms become?
The atoms become smaller in atomic radius.
What happens to the size of the halogen atoms as you go down the group?
atomic number increases
What determines the strength of dispersion forces?
London dispersion forces are dependent on the motion of electrons, their strength increases with the number of electrons in the interacting atoms or molecules. This means that London forces increase as the atomic or molar mass increases.

What happens to the number of electrons as the atomic number increases on the period table?
The electrons increase, too. The atomic number is the number of protons, which gives the positive charge ( a more useful number than the atomic weight ), to balance the positive charge, a roughly equal number of electrons are needed. There are minor differences in some molecular combinations, and some temporary imbalances, but generally the charges balance out.
When heat is added atoms what are two things that happen to those atoms?
If a gas,their moving speed increases,number of collisions increase

An atoms atomic number is the number of what in its nucleus?
atomic number
What do notice on the atomic number of elements in a row as one goes to the right of the table?
The atomic number increases from left to right across a period (row). This is because the atomic number is the number of protons in the nuclei of the atoms of each element. No two elements have the same atomic number. It is the protons that define an element.
What is the atomic number of atoms?
how do you find the atomic number for an element?
Is the atomic number the number of atoms it has?
The atomic number is equal to the number of protons.
