What is true about an element with an atomic number of 8?
Oxygen, element symbol O, is the element that is atomic number 8 on the periodic table. This means every atom of oxygen has 8 protons. Varying the number of electrons forms ions, while altering the number of neutrons makes different isotopes of the element, but the number of protons remains constant.
What has the atomic number 8?
Oxygen

Do all oxygen atoms have 8 protons?
All oxygen atoms have 8 protons, but the nucleus might contain 8, 9, or 10 neutrons. “Light” oxygen-16, with 8 protons and 8 neutrons, is the most common isotope found in nature, followed by much lesser amounts of “heavy” oxygen-18, with 8 protons and 10 neutrons.
What element contains 8 protons in its nucleus?
Oxygen by definition has 8 protons in its nucleus.
What is the atomic number of oxygen?
8
Oxygen/Atomic number
What is atomic number of oxygen?
What atom has 8 protons 8 electrons and 9 Neutrons?
8 17 This isotope of oxygen has 8 protons (atomic number), 8 electrons and 9 neutrons.
What is atomic number of oxygen atom which have 8 electrons and 8 protons?
Answer 6: Oxygen is #8 in the periodic table. That means it has 8 protons and 8 electrons. The number of neutrons varies according to the isotope: the stable isotopes have 8, 9, or 10 neutrons(Wikipedia).
Why does oxygen only have 8 protons?
Oxygen’s 8 electrons are negatively charged, and they orbit the atomic nucleus and balance the positive charge of the 8 protons. The positive charge of 1 proton exactly cancels the negative charge of 1 electron. Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!

What does it mean oxygen has 8 protons?
Oxygen with the symbol O has the atomic number 8 which means it is the 8th element in the table. The number eight also means that oxygen has eight protons in the nucleus . The number of protons and the number of electrons are always the same in an element that is neutral and has no charge. Therefore oxygen has 8 electrons.
Do oxygen atoms always contain 8 neutrons?
It is always less than the sum of the protons, neutrons, and electrons. Since oxygen has 8 protons and 8 neutrons, the atomic mass of oxygen is 16, which is the sum of protons and neutrons. Thus, the correct answer is option (b) 16.
Does the most common isotope of oxygen contain 8 neutrons?
Oxygen has several isotopes, and they have different numbers of neutrons. The most common isotope of oxygen is oxygen-16, which has eight neutrons; however, oxygen-18 is also relatively common, and it has ten neutrons. Both of these isotopes are stable (i.e. not radioactive).
How many atomic numbers does oxygen have?
A single oxygen atom has eight protons, eight neutrons and eight electrons. The number of protons and electrons of an element are equal to its atomic number, which is eight for oxygen. The number of neutrons can be calculated by subtracting the number of protons from the atomic mass, which is 16 minus eight for oxygen.An atom is primarily comprised of neutrons, electrons and protons.
