What is the atomic number in O2?
The atomic number of an element refers to the number of protons in its nucleus. For oxygen (O), the atomic number is 8. So in O2 (oxygen molecule), each oxygen atom contributes its atomic number (8) to the total atomic number for the molecule.
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.
If an atom has an atomic number of 8 and a mass of 18 how many protrons are in the atom?
It has 8 protons. The atomic number of an atom = the number of protons. The mass number is not needed in this problem. The mass number is the number of protons + number of neutrons.
What is oxide atomic number?
The atomic number of oxide depends on the specific element it is composed of. For example, the atomic number of oxygen, which commonly forms oxides, is 8. Other elements forming oxides will have their own unique atomic numbers.
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 does an element have an atomic number of 8?
Oxygen is a non metal element. Atomic number of it is 8.
What number of protons in one atom of an element is that element's?
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
What elements have the atomic number 12 and atomic mass 8?
There is no element with an atomic number of 12 and an atomic mass of 8. Atomic number corresponds to the number of protons in an atom, while atomic mass is the sum of protons and neutrons. The atomic number of an element cannot be smaller than its atomic mass.
Which element has an atomic number of 8?
the element that has the atomic number of 8 is OXYGEN EMAIL @: GUESSWH2@GMAIL.COM IF YOU HAVE MORE QUESTIONS
What is the atomic number of the element oxygen?
Oxygen is a non metal element with atomic number of 8.
Why does an element have the atomic number of 8?
Oxygen has atomic number 8. It is placed in group-16.
What is the atomic number of an atom that has 10 neutrons 8 protons and 8 electrons?
It would be 8, and it is the element oxygen. The atomic number is simply the number of protons in the element.
How many electrons are in an oxygen atom that hasan atomic number of 8?
The atomic number of an element _is_ the number of electrons in one of its atoms. Indeed, a sample of an element can be defined as any combination of atoms with the same atomic number. Oxygen is the element with atomic number 8. It is the element whose atoms have 8 electrons in their neutral state (and 8 protons).
What is oxeygens atomic number?
Oxygen is a gas element. atomic number of it is 8.
What element has eight as its atomic number?
Atomic number 8 belongs to Oxygen!
What corrosive acid is atomic number 8?
Oxygen is a non metal element. Atomic number of it is 8.
How come 8 is the atomic number for oxygen?
Oxygen is a non metal element. Atomic number of it is 8.
