What is the identity of an ion with an atomic number is 16 and mass 33 and 18 electrons?
The ion with an atomic number of 16, mass 33 and 18 electrons is the sulfide ion S2-
What ion has 18 electrons and a mass number of 33 and atomic number of 16?
The sulfide ion, S2-.
What ions have the same number of electrons as argon?
Ca2+ is one of them This is because the mass number of Argon (which is 18) lost 2 electrons (which has a negative charge). Without the impedance of the negative charge, Argon's mass number becomes 20 (instead of 18) and it acts like Calcium (which has the mass number of 20). You can probably figure out the rest of them from the above.
How many protons and electrons are present if the atomic mass is 18 and has 8 neutrons and a charge of -1?
atomic mass = protons + neutronsprotons = atomic mass - neutrons = 18 - 8 = 10 protons (Neon)In ground state, protons = electrons = no charge-1 charge means gain of 1 e-, so number of electrons = 11 electrons
What is the total number of electrons in atom of an element with an atomic number of 18 and a mass number of 40?
ARGON has 18 electrons, with an atomic number of 18 and an Atomic Mass of 40. It has 22 neutrons, is considered a Nobel gas, in that it is inert under most conditions, and is colorless.
What is the total number of electrons in an atom of an element with an atomic number of 18 and a mass number of 40?
ARGON has 18 electrons, with an atomic number of 18 and an Atomic Mass of 40. It has 22 neutrons, is considered a Nobel gas, in that it is inert under most conditions, and is colorless.
What is the mass of an atom with 17 protons 18 neutrons and 17 electrons?
35 (amu)
How many protons nutrons and electrons does argon have?
18 protons and 22 neutrons in the most commonly occurring isotope argon-40. In argon-36 there are 18 neutrons but this isotope is only present in nature at 0.34%
There are 10 neutrons and how many electrons in an atom of oxygen-18?
Because the world is made up like this. Well, a 18O, as it's name shows, has a releatve mass of 18 units. A proton has got a mass of 1 ,a neutron ahd got a mass of 1, and electron has gor a amss of 1/1840 (we dont calculate with a this small mass). So in a 18 relative mass, neutrons + protons = 18. As oxygen is the 8th in the periodic table, it has got 8 atoms. So neutrons + 8 = 18, where neutrons = 10.
An atom has 18 protons 18 electrons and 20 neutrons. This atom has?
This atoms has an atomic number of 18 and an atomic mass of 38.
Atomic weight of electrons in h2o?
Negligible. The mass of an electron is around 1/1840 of an amu, so the 18 electrons in a water molecule contribute a little under 0.01 amu to the total mass of the molecule.
How many protons and electrons does chlorine have?
Chlorine has: 17 Protons 17 Electrons (in a neutral atom i.e. not an ion) (Isotope Mass Number - 17) is the number of Neutrons.
