How many atoms are in hydrogen and chlorine?
There is one atom in Hydrogen and one atom in Chlorine. All elements are composed of only one atom.
How many chlorine atoms are present for every atom in a hydrogen chloride molecule?
There is 1 hydrogen atom and 1 chlorine atom in Hydrogen Chloride.
What is the number of chlorine atoms needed to bond with rubidium?
1: RbCl (Rubidium has 1+ charge, and Chlorine has 1-)
The chemical symbol formula for table salt is NaCL Which element has more atoms in the formula Which element has a larger share of the mass in the formula?
Na(sodium) has an atomic mass of 29.99, or about 30amu. Cl(chlorine) has an atomic mass of 35.453, or about 35amu. therefore, the one with more mass is chlorine. u kno this because the greater number is chlorine's. ^^ o and neither has more atoms in the formula than the other; ther r no subscripts in the formula, which means that ther is only 1 Na atom and 1 Cl atom. ^^ hope this helps! ^_^
Why is chlorine mass number 35.5?
Example 1.2: chlorine consists of 75% chlorine-35 and 25% chlorine-37.** Think of the data based on 100 atoms, so 75 have a mass of 35 and 25 atoms have a mass of 37. The average mass = [ (75 x 35) + (25 x 37) ] / 100 = 35.5So the relative atomic mass of chlorine is 35.5 or Ar(Cl) = 35.5because of isotopes.there is 75% Cl with mass number 35 and 25% with mass number 37so 35 x 3/4 + 37 x 1/4 = 35.5
What is the mass of 1 atom of chlorine?
the mol mass of chlorine atom is 35,453 g/mol. there are 6,022 141 79 × 1023 atoms in one mol. So one atom of chlorine would weigh around 5.83 x10-23 grams. Chlorine,the molecule, would be twice as heavy since the gas consists out of two chlorine atoms.
Why doesn't 1 gram of hydrogen react with 1 gram of chlorine?
One atom of hydrogen reacts with one atom of chlorine forming one molecule of hydrogen chloride (hydrochloric acid). An atom of hydrogen has less mass than one of chlorine so 1 gram of hydrogen contains more hydrogen atoms than one gram of chlorine.
How many atoms are in hydrogen and chlorine?
There is one atom in Hydrogen and one atom in Chlorine. All elements are composed of only one atom.
How many chlorine atoms are present for every atom in a hydrogen chloride molecule?
There is 1 hydrogen atom and 1 chlorine atom in Hydrogen Chloride.
Atomic mass is equivalent to the number of?
The atomic mass is the mass of an atom of that element in AMUs. (Atomic Mass Units)The atomic number, however, is equivalent to the number of protons in an atom of that element.The mass number of an atom is the total number of protons and neutrons in the nucleus of an atom. This is therefore always a whole number. The relative atomic mass of an element is the weighted average of the masses of the isotopes relative to 1/12 of the mass of a carbon-12 atom.It is a weighted average as it takes into account the relative abundances of the different isotopes (atoms of the same element but with different numbers of neutrons) of an element. This number is found in the periodic table.For example chlorine has two isotopes, 35Cl and 37Cl, in the approximate ratio of 3 atoms of 35Cl to 1 atom of 37Cl.The number of protons and neutrons in a 35Cl atom must add up to 35, the mass number. The relative atomic mass of chlorine takes into account both isotopes and is therefore 35.5.
Why does chlorine have an atomic mass of 35.5 write a short example of why this is so using the words protons neutrons isotope atomic number mass number etc?
Chlorine has an atomic mass of 35.5 because the atomic mass of an element is the number of protons plus the number of neutrons. In chlorine, there are always 17 protons (the number of protons in an atom is what makes it whichever element it is), but it is possible to have different amounts of neutrons in the atom. These are called different isotopes of an element. In chlorine, there can be between 17 and 20 neutrons meaning the mass number can range between 34 and 37. The reason that it is written as 35.5 on the periodic table is because that is the average mass number.

Which atom has an average mass not equal to its common isotope?
Hydrogen atom has an average mass not equal to its common isotope. The most common isotope of hydrogen, hydrogen-1, does not have a neutron in its nucleus, while the average mass of a hydrogen atom accounts for the other isotopes of hydrogen which do contain neutrons.
What is The ratio of atom in HCL?
However HCl is 1 atom of hydrogen and 1 atom of chlorine In the sense of one of each thane the raio is 1:1
What is the atomic height of chlorine?
The atomic height of chlorine is around 100 picometers (pm), which is equivalent to 1 angstrom. This represents the average distance from the nucleus to the outermost electron shell of a chlorine atom.
Relative mass of electron?
1/1840 the mass if a hydrogen atom.
