what three elemnts are you referring to. there are 98 naturally occuring elements and 118 elemnts currently on the Periodic Table. if you are referring two the elements of water fire and earth, then i would say that a) that hollistic and pseudo science doesn't belong on on the periodic table and b) the constituents parts of the would be found, such the components of water hydrogen and oxygen, which are atomic number 1 and 8 respectively
CPI stands for Continuous Plating Index. It is a measure used in electrochemistry to determine the ability of a metal to plate out of a solution onto a cathode. It helps predict the likelihood of a metal depositing onto a surface during plating processes.

The number of elements changes periodically because we as humans have the ability to create elements that do not exist in nature. As we create bigger and bigger ones, they are added onto the periodic table of elements.
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.
Sort of. On the one hand, particle physicists can create almost arbitrarily heavy nuclei, and these will continue to be added onto the end of the periodic table and named after important people as they are created. However, all the stable elements, ie all those that last more than a tiny fraction of a second before falling apart into something else, most likely are already on the periodic table, and it's only really these ones that are relevant to most of science.
Fluorine is special in terms of electronegativity because it is the most electronegative element on the periodic table. This means that fluorine has a strong ability to attract and hold onto electrons when forming chemical bonds, making it highly reactive. Its electronegativity value of 3.98 is the highest among all elements.
Fluorine is considered special in terms of electronegativity because it has the highest electronegativity value of all elements on the periodic table. This means that fluorine has a strong ability to attract and hold onto electrons in a chemical bond, making it highly reactive and capable of forming strong bonds with other elements.
Everything. LoL, it was made by a female.
Fluorine holds its electrons most tightly among the elements. This is because fluorine has the highest electronegativity value on the periodic table. Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
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.

As you move from left to right in the periodic table, the number of protons in the nucleus of an atom increases by one in each element. This increase in the number of protons defines the atomic number and determines the element's position in the periodic table.
