Number it's also called the proton number
What is an of 18 protons and 20 neutrons?
You gots Z=18 , the atomic number, where Z is the number of nuclear protons. The number of protons defines the element….and thus we got calcium…. ….and with 20 neutrons we got the 38Ca isotope….the which is rather short-lived….
What element that has 18 electrons?
Palladium is the only element in the periodic table that has 18 electrons in its outermost shell.
What element has 18 as its atomic number?
Argon Argon – Element information, properties and uses | Periodic Table.
Which of the following elements has 18 neutrons?
chlorine Some atoms of chlorine have 18 neutrons in their nuclei.
How many electrons does element 18 have?
So… for the element of ARGON, you already know that the atomic number tells you the number of electrons. That means there are 18 electrons in an argon atom.
What element has a neutron number of 18?
chlorine Some atoms of chlorine have 18 neutrons in their nuclei.
Can chlorine have 18 protons?
Isotopes are atoms with the same number of protons (in the case of chlorine that means 17 protons) but different numbers of neutrons. Chlorine has two common isotopes, Chlorine-35 and Chlorine-37. Chlorine-35 has 17 protons and 18 neutrons and occurs in nature about 75% of the time.
What has 18 protons and 22 neutrons?
Argon So, the atomic number is also (18), and the element with atomic number (18) is Argon with the symbol (Ar). Now we need to find the mass number of Argon. Since, a neutral atom of argon also has 22 Neutrons. So, it is clear that this is not an isotope but a neutral atom of Argon.

Where is fluorine-18?
Fluorine-18 Production. Fluorine-18 is produced with a cyclotron primarily by proton (1H) irradiation of 18O, a stable naturally occurring isotope of oxygen. When the target is liquid H218O, an aqueous solution of 18F-fluoride ion is obtained; when the target is 18O2 gas, 18F–F2 gas is obtained.
How many protons does oxygen-18 have?
8 protons “Light” oxygen-16, with 8 protons and 8 neutrons, is the most common isotope found in nature, followed by much lesser amounts of “heavy” oxygen-18, with 8 protons and 10 neutrons.

How do you make F-18?
Fluorine-18 Production. Fluorine-18 is produced with a cyclotron primarily by proton (1H) irradiation of 18O, a stable naturally occurring isotope of oxygen. When the target is liquid H218O, an aqueous solution of 18F-fluoride ion is obtained; when the target is 18O2 gas, 18F–F2 gas is obtained.
How many neutrons are in o 18?
10 neutrons Because protons and neutrons are roughly equal in mass, an isotope's number is equal to the sum of its protons and neutrons. Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and oxygen 18 has 8 protons and 10 neutrons.
Who found fluorine-18?
History. First published synthesis and report of properties of fluorine-18 were in 1937 by Arthur H. Snell, produced by the nuclear reaction of 20Ne(d,α)18F in the cyclotron laboratories of Ernest O. Lawrence.
