The atomic number is the number of protons in the atom. The number of protons is what determines the element the atom is. This makes the atomic number very important in determining what the atom is.

What type of bond is likely between atoms that are far apart on the periodic table?
Much the same as for other atoms. Differences in atomic number play no role.
Why are elements atomic mass not in strict increasing order in the periodic table?
Elements in the periodic table are arrange by atomic number (number of protons) because various isotopes of elements exist with different atomic masses (atomic mass being determined by the number of neutrons added to the number of protons). The chemical properties are mainly dependent on the electrons, or in some cases the charge of the protons, which is independent of the number of neutrons.
What atomic property affects periodic periodic trends down a group in the periodic table?
The phenomenon that comes into play as we go down toward the bottom of the periodic table through a group is electron screening. As we descend through a group, the atomic number of an atom increases, and so does the number of electrons shells. That means more electrons are between the nucleus (the positive charge) and the valence shell. You'll recall that the valence shell is the outer electron shell, and it is this shell and its population that largely determine the chemistry of an element. When atoms are larger with more electrons shells, the positive charge on the nucleus is "shielded" from the valence shell to a degree by the inner electron shells. That nucleus isn't "holding onto" the valence electrons as tightly. And in atoms that are electron "loaners" like those on the left side of the periodic table, the elements further down a group are "more willing" to loan out valence electrons. This means that they are more reactive. Electron screening serves to "interfere" with the grip the nucleus holds on the valence electrons for atoms farther down a group. On the right side of the periodic table, elements tend to be "borrowers" of electrons, and the translation of the effect of screening on the right is that the elements toward the bottom of a group are going to be less inclined to want to borrow an electron that elements higher up. Again, this is due to electron screening. If all of this is true, then the element of the bottom of Group 1, which is on the left of the table, will be the most reactive electron-loaning element. That's francium, and it is, indeed, the most reactive of the Group 1 elements. Conversely, on the right in the Group 17 elements (the halogens or halides), we'd expect the elements at the bottom to be less reactive than those at the top. And they are. The most reactive halogen is fluorine (at the top of the group), and it is the hungry wolf of the periodic table. Links are provided below.
How did Dmitri Mendeleev discover the periodic table with noble gases?
When Mendeleev proposed his periodic table, the noble gases had not been discovered, so they did not play a part in his development of the periodic table.
What is nitrogen and phosphorus?
Nitrogen is a chemical element that is essential for the growth and functioning of living organisms. It is a crucial component of proteins, nucleic acids, and many other organic compounds. Phosphorus is another chemical element that is vital for life. It is a major component of DNA, RNA, and ATP, which play important roles in cellular metabolism and energy transfer. Both nitrogen and phosphorus are important nutrients for plants and are often found in fertilizers.
What role does the atomic number play in the periodic table of elements?
elements are listed in the periodic table in order of increasing atomic number
What role does atonmic number play in the periodic table?
The atomic number is the amount of protons in an element. The number of protons completely determine what element an atom is.

What role does the electron configuration of an element play?
it possibly shows how many shells an element has to show its atomic number
What is a sentence using elements?
The elements on the periodic table are arranged according to their atomic number and atomic mass.We decided to brave the elements and go to Justine's party anyway, but while we were there we got completely snowed in and had to stay the night.Rockabilly music combines elements of country music with rock 'n roll.The most basic elements of the plot are still there, but other than that the play has been completely rewritten.
Neutrons in potassium?
I'm not sure... but as soon as I figure out the answer I will post the answer... sorry. This answer is better than the one the person before me posted... They said poop and I thought that that was not a true answer for sure and it's nothing to play about and to put a fake answer on here :)
Why isobars are placed at different places in periodic table?
Isobars are not part of the Periodic Table. Isobars connect areas of equal pressure on a weather map. However the term "isobar" (meaning "equal weight") is also used to describe isotopes whose atomic nuclei have similar weight. Isobars are isotopes of two different elements with the same molar mass, or, rather, the same mass numbers. The reason they are placed differently in the periodic table is that chemical properties are determined by the number of protons in the nucleus, and the number of electrons in the outer part of the atom, while mass numbers are determined by the number of (protons plus neutrons). Neutrons play almost no part in chemical reactions; a heavier isotope of any element will undergo exactly the same reactions as a lighter isotope, but just very slightly more sluggishly. One striking example of isobars is Argon-40 (18 protons and 22 neutrons) and Calcium-40 (20 protons and 20 neutrons). Both are the most abundant isotopes of these respective elements, comprising well over 90% of each element as found on the Earth. But argon-40 is a noble gas, roughly 1% of the atmosphere, that refuses to enter into chemical reaction with anything, except under the most extreme conditions. Calcium-40, on the other hand, is a rather brittle and reactive metal that tarnishes rapidly in air, and bubbles away steadily as it reacts with water, producing hydrogen gas in the process. These isobars thoroughly deserve their separate placement in the periodic table.
What causes differences in reactivity?
A Chemical reaction is none other than a play of electrons. Only the electrons take part in chemical reactions. Therefore, reactivity is defined as the tendancy to loose or give away electrons.The difference in the tendency may be due to the number of shells atomic radii etc.If you refer to it on periodic table, you might understand it better..
