Atoms are made up of a nucleus, protons, neutrons and electrons.
The electrons are arranged in shells around the nucleus (made up of neutrons and protons).
The horizontal rows in the Periodic Table are called the periods. The period to which the element belongs corresponds to the number of shells of electrons.
For example, potassium, calcium and scandium all have 4 shells in their atoms.
As you go down the periodic table, the number of shells in one atom of a particular element increases, therefore the size of the atom increases, just like wearing three jackets makes you look bigger (in size) than when wearing just one.

What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
What are the ions on the periodic table?
cations and anions
What is the atomic number and its trend on the periodic table?
The atomic number of an element is the number of protons in the nucleus of one atom of that element. In general, atomic numbers increase as you move to the right and down in the table.
How do you find the number of atomic mass of an atom?
Look at the Periodic Table.
What atom glows with electricity?
neon on the periodic table
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
What is an atom considered on the periodic table?
A atom is not on the periodic table, atoms are inside the elements and compounds on the periodic table if this helps :)
What trend it does the first ionization energy follow going across the periodic table?
The ionization energy increases going across a periodic table.This is because of increasing nuclear charge.
What are the ions on the periodic table?
cations and anions
What is the atomic number and its trend on the periodic table?
The atomic number of an element is the number of protons in the nucleus of one atom of that element. In general, atomic numbers increase as you move to the right and down in the table.
Does the periodic table tell you the number of protons?
The Periodic Table tells you how many protons are in an atom by their Elemental Number. In other words, yes, the Periodic Table tells you how many protons are in an atom.
Why is it that fluorine is the smallest element in the periodic table?
The smallest atom in the periodic table is hydrogen, not fluorine.
Is helium atom a compound?
no in periodic table He
How do you find the number of atomic mass of an atom?
Look at the Periodic Table.
How the atom radius properties generally change as you go from left to right in the periodic table?
The melting temperature properties generally change as you go from left to right in the periodic table by going down/decreasing.
Contains only one type of atom it is found on the periodic table?
All elements in the Periodic Table contain only one type of atom.
How does the bohnr model of the atom relate to the periodic table?
The quantum number of the highest occupied electron orbital in a Bohr model atom corresponds to the atom's period (row) number in the periodic table.
