How many protons are in the element chlorine?
There are 17 protons in each atom of chlorine.
What type of chemical bond can form between an element with 11 protons and an element with 17 protons?
How can chemists state with certainty that no one will discover an element between sulfur and chlorine?
Elements are distinguished based on their number of protons. Chlorine has exactly one proton more than sulfur. Since there cannot be fractions of protons, there can be no element between sulfur and chlorine on the periodic table.http://wiki.answers.com/Why_will_no_one_ever_find_an_element_between_sulfur_and_chlorine#ixzz17vf65uRN
How will the identity and properties of the chlorine change in each case when a proton is added to each case?
No; not if it is an ion. A chlorine atom, for example, has 17 protons and 17 electrons, but a chlorine ion (like when it is in sodium chloride, which is table salt) has 17 protons and 18 electrons. So, if you see an element with 18 electrons, it could be a chlorine ion, an argon atom, or a potassium ion.
Different isotopes of an element have different masses. This is because different isotopes of an element although they have the same number of protons (which defines the chemistry and therefore defines the element) have different numbers of neutrons. Example Chlorine-35 atomic mass approx. 35 (17 protons, 18 neutrons) Chlorine-37 atomic mass approx. 37 (17 protons, 20 neutrons)
The number of protons in Chlorine is relative to its atomic number of 17. The amount of protons will not change, or will become a different element. The 37 refers to the amount of nucleons in the element. The total nucleons is calculated by adding the amount of protons and neutrons, so if we know there are 17 protons, 37-17= 20 neutrons. There are 17 protons and 20 neutrons in Cl-37.
The element that is used to disinfect swimming pools would be Chlorine. Chlorine, atomic number is 17 (number of protons, and electrons), chemical symbol Cl, it's chemical name is obviously.... chlorine, and it's atomic weight/mass is 35.4527 (number of protons... Positive. Number of neutrons... Negative). :) hope my explanation on chlorine helped!!! C:
