Is the atomic number of oxygen 8 because oxygen has a second shell with 8 electrons?

No, the atomic number of oxygen is 8 because it has 8 protons in its nucleus.Oxygen has two electrons in its inner electron shell and 6, not 8, electrons in its outer shell. The fact that it has space for two more electrons before the outer shell is filled is the reason oxygen takes part in the chemical reactions that it does.

The atomic number of an element is the number of protons in its nucleus, which determines its chemical properties. Oxygen has an atomic number of 8 because it has 8 protons. The electrons in the outer shells of an atom can vary, but the number of protons remains constant.

∙ 11y agoThe atomic number of any element is the same as the number of protons in its nucleus, so oxygen's atomic number is 8 because it has 8 protons.

How many electrons in an atom with the atomic number 8?
An atom with atomic number 8 corresponds to oxygen. Oxygen has 8 electrons because the number of electrons in an atom is equal to its atomic number.
How many electrons does this element have O?
The atomic number of an element tells you the amount of of electrons. In oxygen, symbol 'O', there are 8 electrons since the atomic number is 8. For example, the atomic number of Hydrogen is 1, so there is 1 electron in a Hydrogen atom.
How many electrons in oxygen-16?
Oxygen-16 has 8 electrons, as it has an atomic number of 8 which corresponds to the number of electrons in a neutral atom.
What element on the periodic table has 6 electrons?
Carbon has 6 electrons. You can tell because its atomic number is 6, and atomic number is the number of protons. In a neutral atom, the numbers of protons and electrons are equal.
How many protons electrons and neutrons in the element oxgen?
Oxygen has the atomic number 8 and an atomic mass of 16.That means it has 8 protons, 8 electrons, and 8 neutrons.Rules for Calculating Protons, Electrons, and Neutrons in Uncharged CompoundsProtons = atomic numberElectrons = protons = atomic numberNeutrons = atomic mass - protonsRemember, if you have a charged ion, the number of electrons will be different.Oxygen is normally found as O2. A molecule of O2 will have 16 protons, 16 electrons, and 32 neutrons.
How many electrons in an atom with the atomic number 8?
An atom with atomic number 8 corresponds to oxygen. Oxygen has 8 electrons because the number of electrons in an atom is equal to its atomic number.
How many electrons in an oxygen atom that has an atomic number of 8?
Every oxygen atom has eight electrons.
How many electrons are in oxygen atom that has an atomic number of 8?
Every oxygen atom has eight electrons.
How many electrons are in oxygen atom that has atomic number of 8?
8 electrons
What element has 8 protons 8 electrons and 7 neutrons?
Oxygen because its atomic number is eight
An electrically neutral atom of oxygen is likely to have this number of electrons?
Eight, the atomic number of oxygen.
How many electrons does this element have O?
The atomic number of an element tells you the amount of of electrons. In oxygen, symbol 'O', there are 8 electrons since the atomic number is 8. For example, the atomic number of Hydrogen is 1, so there is 1 electron in a Hydrogen atom.
How many electrons in oxygen-16?
Oxygen-16 has 8 electrons, as it has an atomic number of 8 which corresponds to the number of electrons in a neutral atom.
How many protons are presented in an atom which has an atomic number of 19?
The atomic number is also the same as the number of protons and electrons (because they are equal, meaning all atoms are neutral- no charge) for example Oxygen has an atomic number of 8 so it has 8 protons and 8 electrons
What element on the periodic table has 6 electrons?
Carbon has 6 electrons. You can tell because its atomic number is 6, and atomic number is the number of protons. In a neutral atom, the numbers of protons and electrons are equal.
If an isotope of oxygen has 8 protons 10 neutrons and 8 electrons its mass number is?
This certain isotope of oxygen would have a mass of about 18 because electrons weigh almost nothing.
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).
