Why there a decrease of the atomic size from left to right of the periodic table as the no of proton are added one by one?

The protons are positively charged, so they attract the negatively charged electrons. Also, protons are about 2000 times more massive than electrons, so as the number of protons increases, the attraction they have for electrons increases.

How does the atomic mass change when a proton is added to its nucleus?
Since the atomic mass consists of protons and neutrons, adding a proton would add one unit to the atomic massguessing that the number of neutrons doesn't change.
How does atomic radius vary down a group?
Atomic radius increases down a group on the periodic table because with each additional period an energy level is added.
What can we find on the periodic table?
The Periodic table is a table with more than a hundred Elements on it. As of 2010, there are 118. Along with the names of the Elements there is the chemical symbol of the Element, the atomic number, and usually the atomic mass of the Element. The atomic number represents the number of Protons in one atom, and the atomic mass is the mass of the Protons and neutrons added together. The Electrons are not added onto the mass of the Protons and Neutrons because the Electrons are negligible.

How does the relative abundance of each hydrogen isotope affects hydrogen average atomic mass?
The atomic masses shown on the Periodic Table and listed in chemistry textbooks are "weighted" averages of all the naturally occurring isotopes for the particular element in question. The higher the abundance of a particular isotope, the more that isotope contributes to the overall weighted average - that is, to the Atomic Mass on the Periodic Table. Since hydrogen's atomic mass is 1.00 794 atomic mass units, it is clear that the Hydrogen-1 isotope is the most abundant of the three naturally occurring isotopes of hydrogen: protium, deuterium, and tritium. Protium makes up far more than 99% of any naturally occurring sample of hydrogen with deuterium (1 proton and 1 neutron) making up almost all of the rest. Tritium (1 proton and 2 neutrons) is typically present only in trace amounts. To determine the average atomic mass, the masses of the individual isotopes and their relative abundances are measured using a mass spectrometer. Then the fractional abundance is multiplied by the measured isotopic mass for each isotope and the products of these multiplications are then added together to give the recorded atomic mass on the Periodic Table.
How does the atomic radius change from the left to the right horizontal row in the periodic table?
from left to right the atomic radius decreases as the electrons that get added are added in the same shell as they are in the same period. the shielding effect remains constant but the proton number increases which inturn increases the effective nuclear pull on the electrons bringing the electrons closer to the nuclei hence decreasing the radius of the atom
What happens when a proton is added to a carbon?
The resulting element will be nitrogen. If you add 1 proton to carbon(6), it results in nitrogen(7). Both numbers being the atomic number on the periodic table
If You could swallow a capsule of germanium without ill effects what would happen if you added a proton to the nucleus?
Refering back to the periodic table if you add a proton to germanium (atomic number 32), it then has atomic number 33 which is arsenic which is 80-100 times more toxic than Germanium.

What would be formed if one proton is added to this atom?
The atomic number increase with 1.
What factors contribute to the decrease in ionization energy within a group in the periodic table as the atomic number increases?
as atomic number is increase the size of the atom goes on increasing as more number of electron is added to the outer most orbit so the nuclear force exerted by the nucleus on electron is less so the affinity to loose electorn is more as the atomic number is increase that is the reason ionization energy decrease with increase in atomic number
When a radioactive isotope emits a its atomic number increases?
a beta particle. the nucleus is made of protons (+) and neutrons. but neutrons can transform into an electron and a proton. when that happens in the nucleus, the proton stays in the nucleus while the electron shoots out at incredibly high speeds. that high speed electron is called a beta particle. the proton that stays is added to the other protons to increase the atomic number
Does atomic radius increase left to right in the periodic table of elements?
Generally it decreases. There are a few exceptions: the noble gases tend to be quite a bit bigger than the corresponding halogens, and there's a smaller bump as you go from d-block elements to p-block elements.
Suppose a new element is added under francium in the periodic table what would its atomic number be?
The new element would have an atomic number of 119.

What is a proton and neutron added together?
A proton and a neutron added together would be Deuterium without an electron.
