What is chlorine made up of?
Chlorine is an element; it's not "made out of" anything except chlorine atoms. Chlorine atoms are, like all atoms, made of electrons, protons, and neutrons, and the protons and neutrons are made of quarks, specifically up and down quarks (2 up, 1 down for protons; 1 up, 2 down for neutrons).
What 3 elements make up chlorine?
Chlorine itself is an element. It is on the Periodic Table (of the Elements). It is made from protons, electrons and neutrons.
How many neutrons are in the atom chlorine?
Every chlorine atom has 17 protons; 17 is the atomic number of chlorine. However, chlorine has two isotopes that are stable against radioactive decay. These have mass numbers of 35 and 37, which have 18 and 20 neutrons respectively.
How many protons neutrons electrons in the nucleus of chlorine?
Chlorine atom has 17 protons and 17 electrons. The number of neutrons depends on the isotope considered. Chlorine has four isotopes: Cl-35, Cl-36, Cl-37 and Cl-38 with 18, 19, 20 and 21 neutrons respectively. However out of these, Cl-35 and Cl-37 are the most stable isotopes.
Why do the two isotopes of chlorine have the same chemical properties?
The chemical properties of an element are determined by the number of electrons, which is determined by the number of protons. Isotopes vary in the number of neutrons in an atom of the same element (same number of protons). Since neutrons do not influence the number of protons or electrons, they do not affect chemical properties.
What element has 18 neutrons in its atom?
There are several. However, Chlorine is one. Chlorine-35 has 17 protons, 18 neutrons and 17 electrons in its isotopic atom. However, Chlorine-37 has 17 protons, 20 neutrons and 17 electrons in its isotopic atom.
Do atoms have equal electrons and protons?
Not all atoms have an equal number of protons and neutrons. They can, but they don't have to. Helium, for example, has two of each, but carbon (always with 6 protons) can have 6, 7, or even 8 neutrons. The more neutrons, the more likely it is to be radioactive. The number of protons and neutrons gives the atomic weight of an atom. All of the various amounts of neutrons that an element can have are called isotopes of that element.
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.
How many protons and neutrons in Cl-37?
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.
Why the masses of atoms of the same element may different?
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.ExampleChlorine-35 Atomic Mass approx. 35 (17 protons, 18 neutrons)Chlorine-37 atomic mass approx. 37 (17 protons, 20 neutrons)

Where are protons and neutrons of an atom contained?
The nucleus of an atom contains protons and neutrons. Different amount of neutrons- Isotopes. Different amount of protons- Different element.
What is the science element that has 18 neutrons?
Chlorine maybe? It has 17 protons and a mass of 35, so 35-17= 18 neutrons.
Why can 2 atoms of the same element have different numbers of neutrons but must always have the same number of protons explain please?
Without the same number of protons it would be a completely different element on the periodic table and would be considerd an isomer. Take Chlorine-35 and Chlorine-37 for example... they are also isomers because they have a different number of protons. Therefore are different elements.
What 3 elements make up chlorine?
Chlorine itself is an element. It is on the Periodic Table (of the Elements). It is made from protons, electrons and neutrons.
How many protons neutrons and electrons are in chlorine 37?
Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.
How many protons and neutrons does a nucleus of an atom contain?
Each element has a different number of protons and neutrons. So it changes for each element.
