What is the symbol for the ion with 16 protons and 18 electrons?
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–. Thus, the symbol for the ion is 32S2–.
What has 16 protons and 18 neutrons?

What is the symbol of an ion with 15 protons 16 neutrons and 18 electrons?
By referring to a periodic table or table of elements, we see that phosphorus (symbol P) has an atomic number of 15. Thus, each atom has 15 protons. The mass number of the ion is 15 + 16 = 31. Because the ion has 15 protons and 18 electrons (three more electrons than protons), its net charge is 3-.
What is the charge of an atom with 20 protons and 18 electrons?
2+
What is the chemical symbol of an ion with 20 protons and 18 electrons?
Ca2+ represents an ion with 20 protons and 18 electrons. A calcium atom has 20 protons and 20 electrons.
What is the correct charge for an atom with 22 protons and 18 electrons?
+4
Why is oxygen atomic number 8?
On the periodic table of elements, oxygen is represented by the symbol O. It has an atomic number of 8 because it has 8 protons in its nucleus.
Can a single oxygen atom exist?
It’s true that Oxygen, can be termed as O . But one oxygen atom cant exist on its own, because its unstable. Usually any atom needs 8 electrons in its outer orbit in order to stay stable. But, the Oxygen atom has 6 electrons in its outer orbit.
What are 3 uses for oxygen?
Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.

What does the 17 represent in oxygen 17?
The neutron flux slowly converts 16O in the cooling water to 17O by neutron capture, increasing its concentration. The neutron flux slowly converts 17O in the cooling water to carbon-14, an undesirable product that escapes to the environment….Oxygen-17.

How do we calculate atomic mass?
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
What is atomic number formula?
Examples of Atomic Number The atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom. Atomic number = Number of protons. For example, in a sodium atom, there are 11 electrons and 11 protons.
Where is the atomic mass?
At the upper left is the atomic number, or number of protons. In the middle is the letter symbol for the element (e.g., H). Below is the relative atomic mass, as calculated for the isotopes found naturally on Earth. At the very bottom is the name of the element (e.g., hydrogen).
What is the formula of atomic weight?
Atomic number: Number of protons present in the nucleus is called atomic number (Z) of an element. Atomic weight: The sum of mass number of proton and mass number of neutron is called atomic weight or atomic mass number (A). Z = 19 and A = 39 as per atomic weight definition.
