What else can I help you with?
When you go down the periodic table what happens to the electronegativity?
Increase -tac
Do the elements in the periodic table have the same mass?
No! The mass of one atom of each element increases as you move down and to the right on a periodic table. The mass of an atom of a particular element is called its atomic mass.
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 part on periodic table shows number of shells of nucleus of atom?
The period number is equal to the number of shells. Periods are the horizontal rows on the periodic table. The number of shells increases down a group.
When does the radius of an atom decreases or increases?
The radius of an atom typically decreases when moving from left to right across a period in the periodic table due to increasing nuclear charge. It increases when moving down a group in the periodic table due to the addition of energy levels.
What happens to elements as you move down the periodic table?
they do something
When you go down the periodic table what happens to the electronegativity?

No! The mass of one atom of each element increases as you move down and to the right on a periodic table. The mass of an atom of a particular element is called its atomic mass.
What is an example of periodicity?
A good example of periodicity would be the size of an atom which decreases across the Periodic Table but increases down the column
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.
Describe the number of valence electrons in each atom as you move down group 2 in the periodic table?
As you move down group 2 in the periodic table, the number of valence electrons in each atom remains the same, at 2. This is because elements in the same group have the same number of valence electrons, regardless of the period they are in.
What part on periodic table shows number of shells of nucleus of atom?
The period number is equal to the number of shells. Periods are the horizontal rows on the periodic table. The number of shells increases down a group.
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.
When does the radius of an atom decreases or increases?
The radius of an atom typically decreases when moving from left to right across a period in the periodic table due to increasing nuclear charge. It increases when moving down a group in the periodic table due to the addition of energy levels.
How was mendeleevs periodic table like todays periodic table?
Mendeleev's periodic table arranged elements by increasing atomic mass and grouped elements with similar properties together. Today's periodic table is similar, but it is arranged by increasing atomic number, which reflects the number of protons in an atom's nucleus. Both tables also show periodic trends in properties as you move across and down the table.
What is an element referring to the periodic table?
An element is an atom with a specific number of protons. For example, any atom with just one proton is hydrogen. An atom with two protons is helium. An atom with three protons is lithium. And so forth. Write them all down in sequence, starting new rows at the correct point, and you have a periodic table of elements.
What happens to the atomic radius as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
