What element has 17 protons and 18 neutrons?
Name Chlorine
What is the mass number of a chlorine atom with 17 protons and 18 neutrons?
35
What is the symbol of the ion having 17 protons and 18 electrons?
So, Mass number = 17 + 18 = 35 a.m.u. Symbol of the positively charged Y is Y +. This chlorine ion also has 18 neutrons.
Why does this indicate that most chlorine atoms contain 18 neutrons?
The ratio of two isotopes is 3.44 which is greater than 1. Therefore,chlorine-35 is greater than chlorine-37 in a mixture of two isotopes. We know that atomic number of chlorine-35 is 17. Hence, the chlorine-35 is most which contain 18 neutrons.
Why does chlorine have 2 isotopes?
The mass number is a tally of the number of protons and the number of neutrons in an atom’s nucleus. Since all atoms of chlorine contain 17 protons, chlorine-35 and chlorine-37 differ in the number of neutrons each one has. Adding or removing a neutron from an atom’s nucleus creates isotopes of a particular element.
How many protons neutrons and electrons are in chlorine 37?
). Its nucleus contains 17 protons and 20 neutrons for a total of 37 nucleons.
How many atoms does chlorine have?
Cl2-A Diatomic Molecule With seven electrons in its outermost orbit–one electron short of a “stable eight”– the element chlorine exists in nature as a diatomic molecule. This arrangement allows two chlorine atoms to share their outermost orbit electrons, achieving stability, compared to the single atom.
How many atoms does 2 cl2 have?
If you have a mole of cl2, then you have 6.02 * 10^23 molecules of cl2. If you want to calculate for atoms however, you can see that each molecule has two atoms of cl. Therefore you have 2* 6.02 * 10^23 chlorine atoms.
