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.
What information is listed in an elements square on the periodic table?
Element name is listed in the center.Element atomic number on the top left.Element atomic mass on bottom left.
What happen to the atomic as you from the bottom to the top of the periodic table?
As you move from the bottom to the top of the periodic table, the atomic size decreases. This is because the number of protons in the nucleus increases, leading to a stronger pull on the electrons. Electrons are added to the same energy level while moving up the table, resulting in a smaller atomic radius.
What happens to the atomic mass of elements as you move across and down the periodic table?
As you move across the periodic table from left to right, the atomic mass generally tends to increase due to the addition of more protons in the nucleus. When moving down a group, the atomic mass increases because new energy levels are added, leading to the incorporation of more electrons and protons.
Which of these describes atomic radii as one moves from top to bottom within a group?
The atomic radius increases from top to bottom within a group.
What is the difference between atomic mass unit and atomic mass?
Atomic mass unit is the number on the bottom of the Chemical. However, the atomic mass is the number on the top of the chemical minus the number on the bottom. b.t.w The no. of neutrons = top no. minus bottom no.
How many neutrons are in alumnium?
14 - Subtract atomic mass(usually bottom #) from atomic number(usually top #).
Why the relative atomic mass of an element in th periodic table in fractional form?
The top left number is the mass (neutrons&protons) and the bottom left number is the atomic number(protons)
Towards the bottom of the periodic table does the atomic mass increase or decrease?
Towards the bottom, atomic mass increases. Atomic number also increases.
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.
What information is listed in an elements square on the periodic table?
Element name is listed in the center.Element atomic number on the top left.Element atomic mass on bottom left.

What is the mass number and atomic number of nitrogen?
Nitrogen has a mass number of 14 and an atomic number of 7.
Are protons the number on top or the bottom?
For a given isotope of an element, the "top number" (e.g. 14C or carbon-14) is the atomic mass number, the total of neutrons and protons. The bottom number, if displayed, is the atomic number (e.g. 6C all isotopes of carbon have 6 protons). To find the number of neutrons, subtract the atomic number from the isotopes atomic mass number. Here, 14C will have 8 neutrons, and the result is that it is an unstable radioactive isotope. Many stable elements, however, have many more neutrons than protons.
