Is there an easy way to remember that on the periodic table the atomic number goes on top of a square and the atomic mass is the one the bottom?

To be honest, as far as I know, no.
However, I don't think it's a horrible lot you have to remember... and I'd be surprised if you don't get a Periodic Table when going to an exam.
Well if you can remember the atomic number the Atomic Mass is a little more or less than the doubled atomic number.
Atomic numbers are pretty simple to memorize. If your test is multiple choice even easier. Ask your teacher if you can use a blank periodic table unless that's the test

What happens to the atomic size from the top to the bottom of the periodic table?
The atomic size increase from top to bottom of periodic table. As the number of shells increases from top to bottom, the atomic size increases.
Do radium have a small atomic number?
No. In fact radium is at the bottom of the periodic table where the heaviest elements are. Its atomic number is 88 (compare with carbon, the standard element; atomic number 6)
How do you tell figure out the atomic mass?
Atomic mass is the number of protons + the number of neutrons in the nucleus of an atom. On the periodic table, the average atomic mass of an element will the be number at the bottom of each box.
Where do lanthanids and actinides fit into the periodic table?
Lanthanides (elements with atomic number 57-71) and actinides (elements with atomic number 89 to 103) are placed at the bottom of the periodic table.
What happens to atomic radius as you move from bottom to top of the periodic table?
atomic radius decreases from bottom to top of the periodic table.
What happens to the atomic size from the top of the periodic table to the bottom?
The atomic size increase from top to bottom of Periodic Table. As the number of shells increases from top to bottom, the atomic size increases.
What happens to the atomic size from the top to the bottom of the periodic table?
The atomic size increase from top to bottom of periodic table. As the number of shells increases from top to bottom, the atomic size increases.
Where would the atomic number 113 go in the periodic table?
on the bottom
What is the meaning of the number printed at the bottom of the periodic table?
The atomic mass.
Towards the bottom of the periodic table does the atomic mass increase or decrease?
Towards the bottom, atomic mass increases. Atomic number also increases.
Where are the antinides on the periodic table?
Actinides comprise of atomic number 90-103. They are placed at bottom of periodic table.
What number do the protons determine?
The atomic number (Displayed on the bottom left of the elements symbol on the periodic table)
Do radium have a small atomic number?
No. In fact radium is at the bottom of the periodic table where the heaviest elements are. Its atomic number is 88 (compare with carbon, the standard element; atomic number 6)
Atomic number is equaled to what on the periodic table?
Atomic number is the bottom number on an element in the periodic table. It is the proton number, so tells you how much protons are in an element. EXTRA: you can find the neutron number by subtracting the mass number from the proton number.
How do you tell figure out the atomic mass?
Atomic mass is the number of protons + the number of neutrons in the nucleus of an atom. On the periodic table, the average atomic mass of an element will the be number at the bottom of each box.
What does the number of protons of an atom indicate on the periodic table?
In the periodic table, atomic numbers are given alongside the symbol of each atom. As atomic number is always equal to number of protons, so the Periodic Table also tells us about the number of protons in different atoms...
Where do lanthanids and actinides fit into the periodic table?
Lanthanides (elements with atomic number 57-71) and actinides (elements with atomic number 89 to 103) are placed at the bottom of the periodic table.
