Why is it when an atomic number increases in a group the size of the atoms increase?
As the atomic number increases within a group, additional electron shells are added to the atom, leading to a greater distance between the outermost electrons and the nucleus. This increase in distance results in a larger atomic radius. Additionally, while the effective nuclear charge increases, the shielding effect from inner-shell electrons mitigates this attraction, allowing outer electrons to be held less tightly and thus increasing atomic size.

What increases in the periodic table?
As you move from left to right across a period in the periodic table, the atomic number increases. This increase in atomic number corresponds to an increase in the number of protons in the nucleus of the atom.
Why does the atomic number increase in a period when the size of atoms decreases?
In a period on the periodic table, the atomic number increases as protons are added to the nucleus of each successive element. This increase in positive charge attracts electrons more strongly, pulling them closer to the nucleus. As a result, even though more electrons are being added, the size of the atoms decreases due to the stronger effective nuclear charge that outweighs the electron-electron repulsion. Thus, the atomic size decreases while the atomic number 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.
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.
What increses in the periodic table?
As you move from left to right across a period in the periodic table, the atomic number increases. This means there is an increase in the number of protons in the nucleus of the atoms. Additionally, as you move down a group or family in the periodic table, the number of energy levels or electron shells increases.
What happens to the number of electrons in an atom when the atomic number increases?
When the atomic number increases, the number of protons in the nucleus also increases. Since atoms are electrically neutral, the number of electrons in the atom would also increase to match the number of protons, maintaining a balanced charge.

Why does the electronegativity increase as the atomic number increases?
The number of electrons increases with the atomic number. So the electronegativity increases with the atomic number. Not quite. Electronegativity doesn't consistently increase with atomic number. For example, F is more electronegative than Na, even though Na has a higher atomic number.

What is the trend of boiling point ang melting point when the atomic number is increases?
As atomic number increases, boiling point/K increases due to there being more electrons, which create a larger strength of negative charge around the nucleus of the atom. This affects the van der waals' forces (the forces of attraction between molecules or atoms), and they become stronger. With stronger forces, it requires more energy input to change the state of the element - resulting in a higher boiling/melting point. [:

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
Why does the molar mass increase by more than one unit when the atomic number increase by one unit?
Because atomic mass is the sum of both atomic number and number of neutrons in an atom.
What generalization can you make about the trend in electonegativity as atomic number increases in a period?
As atomic number increases within a period, electronegativity generally increases. This trend occurs because atoms have more protons, which enhances their positive charge and ability to attract electrons. However, this trend can be influenced by other factors, such as electron shielding and the overall atomic structure. Therefore, while there is a general increase, exceptions may arise due to specific elements' unique properties.
