What element is the atomic number 8?
Oxygen come on now you breath it. :)
What is the atomic number used for?
The atomic number of an element is the number of protons found in the nucleus of an atom. The atomic number is identical to the charge number of the nucleus. For example, the atomic number of Oxygen is 8.
Why is oxygen's atomic number 8?
Each oxygen atom contains 8 protons in its nucleus. The atomic number of a chemical element (also known as its proton number) is always the number of protons found in the nucleus of an atom of that element, and identical to the charge number of the nucleus. It is conventionally represented by the symbol Z.
Is a oxygen a atom or molecule?
Oxygen is an atomic element. It is found in many molecules.
Is oxygen a molecule or a atom?
Oxygen is an atomic element. It is found in many molecules.
The number of protons in an element is the?
The number of protons in an element is the atomic number, which can be found in the top right corner of the box containing the element.
Which elemental gas with an atomic number of 8 is essential for most terrestrial life?
Element with atomic number 8 is Oxygen(O2). It is the most abundant element on earth. It is very reactive, so most sources of oxygen are found in the crust in combined state with other elements.
An explination of what mass number and atomic number are?
The atomic number refers to the number of protons in the element. And since the number of protons = number of electrons, the atomic number is also the number of electrons in the element. The mass number of an element refers to the number of neutrons and protons in the element. &since electrons are negligible in mass, the number of neutrons can be found out by subtracting the atomic number from the mass number. Take for example, oxygen. Oxygen has an atomic number of 8 and a mass number of 16. Hence, from the atomic number it can be derived that it has: 8 electrons 8 protons While from the mass number, it can be derive that it has: 16-8 = 8 neutrons
How is the atomic weight of an element found?
you add the number of protons (the atomic number) to the number of neutrons
What does the 8 above oxygen on the periodic table mean?
A superscript 8 on the left side of an atomic symbol means the particular isotope has a mass number of 8. A superscript number on the right side of an atomic symbol should mean that the symbol is for an ion with charge of 8, but this would normally also have a plus or minus sign associated with it.
The atomic number of an element is the number of?
Is the number of protons or electron found in a given (neutral) element.
What is the element number on an element?
the number on an element is known as the atomic number. It states the number of protons or electrons found in an atom
