Chemistyr homework?
complete the following Protons Electron Nuetrons
A.chlorine-35 .....______ ______ _____
could you guys tell me how to do this plaese i need to turn it tomorow and i still need more ={
Answer:
Protons are equal to atomic number.
Chlorine-35 has 17 protons.
Electrons are equal to atomic number as well. The reason is because electrons are negatively charged and protons are positively charged. If you don't have the same number of each, you'll end up with some type of ion.
Chlorine-35 has 17 electrons.
To find number of neutrons, subtract atomic number from the mass number.
35 - 17 = 18 neutrons.
atomic number=number of protons
in a neutral atom, number protons=number of electrons
mass number=sum of protons and neutrons
Cl-35 is neutral, and has atomic number 17...leaving how many neutrons?
Chlorine 35 means that 35 is its Atomic Mass.
It has 17 Protons (Its Atomic Number), and 18 Neutrons,
These together give its Atomic mass of 35.
It also has 17 electrons as a stable element ...Its a neutral atom. (17 protons (+) and 17 Electrons (-).
As a gas alone , it exists as a 'Diatomic' molecule as CL².
(The ' ² ' is normally a subscript but can't be written here).
atomic number - number of protons + number of elctrons
atomic mass - number of protons + number of nuetrons
what exactly do you want ? atomic number or atomic mass?
