A chlorine atom has 17 protons, 18 neutrons, and 17 electrons.
Can chlorine have 18 electrons?
Chlorine gains an electron, leaving it with 17 protons and 18 electrons. Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion.
Why does chlorine have 18 neutrons?
An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So although chlorine has a mass number of 35 which means it has 18 neutrons, it can also have a mass number of 37, which means it has 20 neutrons.
Does chlorine have 16 neutrons?
A chlorine ion contains 17 protons, 16 neutrons, and 18 electrons.
What chlorine has 20 neutrons?
Chlorine-37 . ). Its nucleus contains 17 protons and 20 neutrons for a total of 37 nucleons.
What has 17 protons and 18 neutrons?
Chlorine-35 has 17 protons and 18 neutrons. It's considered a stable isotope and is the most abundant isotope of chlorine, with approximately 76%...
What element has 17 protons and 18 neutrons?
An element with 17 protons will always be chlorine . However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So although chlorine has a mass number of 35 which means it has 18 neutrons, it can also have a mass number of 37, which means it has 20 neutrons.
Why does chlorine have 2 isotopes?
Adding or removing a proton from an atom's nucleus changes that atom's atomic number and creates a different element. Chlorine-35 and chlorine-37 are both isotopes of the element chlorine. ... Since all atoms of chlorine contain 17 protons, chlorine-35 and chlorine-37 differ in the number of neutrons each one has.
Why is chlorine 1?
Atoms in their natural state have a one to one ration between the positive charges of the protons and the negative charges of the electrons. ... There are 18 electrons and 17 protons, so the chlorine atom has become a charged chlorine ion with a charge of negative one (-1).
Is chlorine a cation or anion?
| Family Element Ion Name | VIIA Fluorine Fluoride anion | Chlorine Chloride anion | Bromine Bromide anion | Iodine Iodide anion |

Why can't chlorine have 16 protons?
All chlorine atoms have 17 protons. If an atom has 16 protons – it's sulfur . ... In the isotope symbol of each atom, there is a superscripted (raised) number. This number is also used in the name of the atom (i.e., carbon-12).
Why chlorine is not a whole number?
For example, the relative atomic mass of chlorine is 35.5 rather than a whole number. This is because chlorine contains two different isotopes, chlorine-35 and chlorine-37.
Which element usually has 7 neutrons?
Carbon atoms with 7 neutrons have an atomic mass of 13 (6 protons + 7 neutrons = 13). These atoms are the isotope called carbon-13.
Is chlorine 37 radioactive?

Is chlorine a single atom?
2.8. Elements can be made of one atom, like He, or be elemental molecules, such as hydrogen (H 2 ), oxygen (O 2 ), chlorine (Cl 2 ), ozone (O 3 ), and sulfur (S 8 ). Atoms are not drawn to scale. Some elements are monatomic, meaning they are made of a single (mon-) atom (-atomic) in their molecular form.
