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.

∙ 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 are in a oxygen atom?
There are 8 electrons in a single neutral oxygen atom.The atomic number of oxygen is 8, because it has 8 protons in its nucleus. In an elemental, neutral, atom of oxygen the number of electrons will match the number of protons. There are 8 electrons in a neutral oxygen atom.Note that oxygen can become an ion under certain circumstances, and we need to specify the neutral atom to state how many electrons there are in oxygen.
How many neutrons and electrons does oxygen-16 have?
8 since the atomic number equals the number of protons!!
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.
What is the amount of protons neutrons electrons in oxygen?
8 protons 8 electrons and 8 neutrons. Oxygen has the atomic number 8, so it has 8 protons, 8 electrons. The number of neutrons would be mass number-atomic number, so 15.9994-8=7.9994, so rounding would be 8 neutrons.
How many protons and valence electrons does oxygen have?
Oxygen has 8 protons- the atomic number is the number of protons an atom has. A single oxygen atom contains 8 electrons to balance this charge, but oxygen is diatomic- meaning it will be O2 instead of just one Oxygen molecule.
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 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
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).
What is the symbol of atomic number 8 atomic weight 16 electrons 10?
that is oxygen with 2 extra electrons. O^-2
How many electrons do oxygen atoms have?
The electrons in an element is the same as the protons and the atomic number. 8
6 The atomic number of oxygen is 8 because oxygen has?
The atomic number of oxygen is 8 because oxygen has 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.The Atomic Number is a count of how many Protons are present in an atom of an element.The element Oxygen has 8 Protons in its atomic nucleus and therefore has an Atomic Number of 8.Note: in an electrically neutral atom the number of electrons in the electron cloud exactly matches the number of Protons in the nucleus of the atom, therefore electrically neutral oxygen will also have 8 electrons.
What do you count to find the atomic number?
You count the number of electrons in the shell of the atom you want to find the atomic number of, For example oxygen has two shells of electrons on the 1st shell there are 2 electrons and on the 2nd there are 6 electrons. If you are finding the atomic number from the periodic table then it's always the smaller number, it doesn't matter if the smaller number is on the top or the bottom because that varies between different tables.
