How many subatomic particles are in a Oxygen atom that has a -2 charge?
protons:
neutrons:
electrons:
Oxygen atom has an atomic number of 8 so it has 8 protons. O^2- will have two more electrons or 10. Neutrons: don't know. You didn't give a mass number. #protons + #neutrons = mass number. You know protons and when you know mass number you can calculate #neutrons.
protons: 8
neutrons: ?
electrons: 10
To determine the number of protons, neutrons, and electrons in an oxygen atom with a -2 charge, we can use the atomic number and mass number of oxygen.
The atomic number of oxygen is 8, which represents the number of protons. Since the charge on the atom is -2, it means the number of electrons is two more than the number of protons. So, in this case, there are 10 electrons.
To find the number of neutrons, we subtract the atomic number from the mass number of oxygen. The mass number of oxygen is usually 16, but in this case, we need to adjust it based on the charge. The charge for an oxygen ion is -2, so the mass number will be 16 + 2 = 18. Subtracting the atomic number (8) from the mass number (18), we find that there are 10 neutrons in this oxygen ion.
Therefore, the number of subatomic particles in the oxygen atom with a -2 charge is as follows:
Protons: 8
Neutrons: 10
Electrons: 10
To determine the number of subatomic particles in an oxygen atom with a -2 charge, we need to understand the atomic structure of oxygen.
- Oxygen has an atomic number of 8, which means it has 8 protons. Protons carry a positive charge, and the number of protons determines the element's identity.
Since the oxygen atom has a -2 charge, this means it has gained two extra electrons. Electrons carry a negative charge equal to that of protons but in the opposite direction.
To calculate the number of neutrons, we need to know the oxygen isotope you are referring to. Most oxygen atoms have 8 neutrons, but there are a few isotopes with different numbers of neutrons.
So, to summarize:
protons: 8
neutrons: It depends on the isotope. Generally, it is 8, but some isotopes may vary.
electrons: 10 (8 original electrons + 2 acquired electrons)
