Does oxygen have 8 or 10 electrons?
In an oxygen atom, there are 8 protons and 8 electrons. Most oxygen atoms also have 8 neutrons, but it is possible for an oxygen atom to have 9 or 10 neutrons. They are just rarer. The oxygen we breathe is not in atomic form.
How is atomic mass calculated?
Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
What is O2 ion?
Oxide(2-) is a monoatomic oxygen. Binary compounds of oxygen containing the anion O(2-). The anion combines with metals to form alkaline oxides and non-metals to form acidic oxides.
Why does O2 have 16 electrons?
Explanation: Oxygen has an atomic number of 8 , and the mass number of an atom is the sum of its atomic number plus its neutron number. We got the mass as 16 units, and so it’ll have 16−8=8 neutrons.
How many electrons does oxygen lose?
An oxygen molecule is O2. Each oxygen atom has 8 electrons, so there are 16 electrons in an oxygen molecule. Valence electrons of silicon are 8. Thus to complete its octate it either needs to loose 4 elctrons or gain 4 electrons, but this requires high amount of energy/heat.
