Is chlorine gas an element or compound?
Chlorine is an element, but chlorine gas in it's pure state is a diatomic molecule, meaning it is two of the same atom covalently bonded. all halogen gases do this, plus a couple others. A good way to remember this is HOFBrINCl. Hydrogen, Oxygen, Florine, Bromine, Iodine, Nitrogen, and Chlorine. All of them ARE NEVER alone in their pure form, they are always diatomic.
Is chlorine a scientific name?
Yes, chlorine is a scientific name in English language; other maes in others languages.
What elements does not occur as a diatomic molecule?
Many elements do not exist as diatomic molecules. Metals, like iron, copper, silver, lead, etc. Even some nonmetals, helium, argon, sulfur, etc. Only a few do exist as diatomic molecules, hydrogen, oxygen, nitrogen, chlorine, fluorine, bromine, and maybe astatine.
Do metalloids always have high melting temperatures?
No, metalloids do not always have high melting temperatures. While some metalloids like boron and silicon have relatively high melting temperatures, others like arsenic and antimony have lower melting temperatures. The melting temperature of a metalloid depends on its specific atomic structure and bonding characteristics.
Does chlorine atom has a smaller radius than chlorine ion?
Yes, considerably so. In general, positive ions are smaller than their neutral atoms, and negative ions are larger than their neutral atoms.
What is a diatomic molecule-?
Diatomic moleculesDiatomic molecules are molecules composed of two atoms ("di" meaning 2 and "atomic" for atoms) of the same or of different elements. All the elemental gases like hydrogen, nitrogen, oxygen, fluorine, chlorine, etc., form diatomic molecules - except the inert gases, of course. We find H2, N2, O2, Fl2, Cl2, and others in chemical equations because the gas atoms don't want to hang out by themselves in their elemental form. The atoms would rather (and actually do) travel around with a "buddy" until such time as they enter into a chemical reaction.We find that carbon monoxide, CO, is a diatomic molecule, and then there are NaCl (table salt), HCl (hydrochloric acid), and a list of other chemical compounds of similar structure (meaning two atoms paired up) that could fill a book. We won't fill a book here, but we will supply you with a link to the Wikipedia post on the diatomic molecule so you can do some further reading. Oh, and you'll find that link below.
How does chlorine bond with others to form a molecule?
Gaining an electron chlorine fprms covalent bonds.

Where does the 0.5 in chlorine's atomic mass come from?
There are different isotopes of the element. Isotopes are atoms of an element that have different amounts of protons, so the isotopes with more protons weigh more because there is more mass in the atom. Some isotopes are more common than others, and the atomic mass is a weighted AVERAGE of all the isotopes of that element. On most elements there is a large difference between the most common and lesser common isotopes, but chlorine has 2 isotopes that are very close. So the average ends up between the two numbers. The actual weight of 1 atom will never be something.5 because protons and neutrons weigh 1amu and electrons weigh 0. But in most cases the sample of a chemical you use will be a mixture of the isotopes, so the .5 weight will be correct.
What is an example of a molecular formula for a diatomic molecule?
You can easily remember the formulas of the homonuclear diatomic elements using the saying Never Have Fear Of Ice Cold Beer. This stands for N2, H2, F2, O2, I2, Cl2, and Br2.
Why does chlorine have a mass number of 35.5 when you cannot have half a proton or neutron in the nucleus?
First some basic terminology for the periodic table:Atomic number: The number of protons in the element's nucleus.Atomic mass: The total mass of the protons, neutrons, and electrons that make up a particular isotope of an elementAtomic weight: The average weight of an elemental atom, taking into account the relative abundance of the element's isotopes. This is getting to the crux of your question - I may not have explained atomic weight that well, but the example of Cl below will better illustrate what I mean by atomic weight. (And btw, 'mass number' isn't a correct way to refer to the atomic weight.)Take the example of Chlorine, or Cl. There are two main isotopes of Cl, 35Cl and 37Cl (there are others but they are very rare, so we'll simplify). We'll now calculate the atomic weight (or as you referred to it incorrectly, mass number) based on the relative abundance and atomic masses of these two isotopes. I'm going to round to even numbers to symplify.Chlorine has an atomic number of 17, so we know all of its isotopes have 17 protons (and therefore 17 electrons).35Cl has 17 protons, 17 electrons and 18 neutrons, while 37Cl has 17 protons, 17 electrons, and 20 neutrons.Because 35Cl and 37Cl have the same number of protons and electrons (as do all isotopes of the same element) they behave very similarly. They are isotopes since they have different numbers of neutrons, and therefore 35Cl and 37Cl have different atomic masses.35Cl has an atomic mass of 35, and 37Cl has an atomic mass of 37.Since 35Cl makes us almost 77% of all Cl isotopes on earth, and 37Cl makes up almost all of the remaining 23% of Cl isotopes on earth, we get the atomic weight by calculating the average weight of Cl.Atomic weight = (% abundance of isotope A * atomic mass of isotope A) + (% abundance of isotope B * atomic mass of isotope B)Atomic weight of Chlorine = (0.77 * 35) + (0.23 *37)Atomic weight of Chlorine = 35.46
What side of the of the periodic table are the halogens located?
The diatomic molecules in the periodic table are also known as the Fab 7. They are in a row such that they create kind of an upside down L (excluding Hydrogen at the top left): Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, Iodine, and lastly, Hydrogen.
