What has 18 protons and 19 neutrons?Thus, chlorine-37 and argon-37 are isobars. Chlorine-37 has 17 protons and 20 neutrons in its nucleus, whereas argon-37 has a nucleus comprising 18 protons and 19 neutrons.
Article first time published onWhat is the charge of an ion that contains 20 protons and 18 electrons?
For example, a neutral calcium atom, with 20 protons and 20 electrons, readily loses two electrons. This results in a cation with 20 protons, 18 electrons, and a 2+ charge.
What ion has 18 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. The different types of chlorine are called isotopes of chlorine.
Which is the atomic number of an atom that forms an ion with 18 electrons and a charge of 2 +?
Explanation: A certain element forms an ion with 18 electrons and a charge of +2. … Recall that atoms have the same number of electrons as protons, and the atomic number of an atom is the number of protons it has. So, the atom in question is the atom whose atomic number is 20…..that’s calcium (Ca).
What is the symbol for a neutral atom containing 18 protons and 22 neutrons?
Given the number of protons is \[18\]. 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.
What has 16 protons and 18 neutrons?
The atomic number of sulfur is 16. The ion has 18 electrons that mean sulfur carries the charge of -2.
What isotope has 17 electrons and 18 neutrons?

How many protons does an atom with 18 electrons have?
There are 17 protons in an ion with 18 electrons and a -1 charge.
What the complete element symbol of a species that has 17 protons 20 neutrons and 18 electrons?
Chlorine-37. ). Its nucleus contains 17 protons and 20 neutrons for a total of 37 nucleons.
Which element in the periodic table that has 19 electrons?
So if you look for potassium (symbol K in the periodic table), you will find that it has the atomic number of 19. This tells you that potassium has 19 protons and – since the number of protons is the same as the number of electrons- also 19 electrons.
What atom has 19 protons 22 neutrons and 18 electrons?
The element is NECESSARILY potassium.
Which element contains 84 protons?
Polonium, (element 84), was discovered in 1898 and named after Poland, the homeland of Marie Curie (Ne Sklodowska) who found it with her husband Pierre Curie.

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 particle has 18 electrons 20 neutrons?
Explanation: A particle P has 18 electrons, 20 neutrons and 19 protons. This particle must be a cation.
What is 19 on the periodic table?
Potassium – Element information, properties and uses | Periodic Table.
Is GE a metal?
germanium (Ge), a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silvery-gray metalloid, intermediate in properties between the metals and the nonmetals.
What is the element with 20 protons?
Ca has 20 protons, so neutral it would have 20 electrons, but according to the charge, 2 electrons have been lost.
What is the charge of an ion that contains 16 protons and 18 electrons?
Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32. Because the ion has 16 protons and 18 electrons, its net charge is 2–.
What is the charge of an ion that contains 15 protons and 18 electrons?
Explanation: Protons are positively charged, while electrons are negatively charged. If the ion has 18 protons and 15 electrons, it has 3 more protons than electrons, therefore, the ion has an overall positive charge of 3+.
What is Ca on the periodic table?
Calcium was named after the Latin term calx meaning lime, and is a reactive silvery metallic element found in Group 2 of the periodic table. It was first isolated in 1808 in England when Sir Humphry Davy electrolyzed a mixture of lime and mercuric oxide.
