Why is the atomic number of oxygen is 8?
On the periodic table of elements, oxygen is represented by the symbol O. It has an atomic number of 8 because it has 8 protons in its nucleus.
What is the atomic number 8?
O Oxygen The Elements, sorted by Atomic Number
| Atomic Number | Symbol | Name |
|---|---|---|
| 6 | C | Carbon |
| 7 | N | Nitrogen |
| 8 | O | Oxygen |
| 9 | F | Fluorine |
How many electrons of oxygen have if its atomic number is 8?
8 electrons 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.
Is oxygen number 8 on the periodic table?
Oxygen is a chemical element with symbol O and atomic number 8. Classified as a nonmetal, Oxygen is a gas at room temperature.
What is the atomic number of 8 protons?
Oxygen Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!
What element has 8 protons 8 electrons and 11 neutrons?
Explanation: Well, the atom will 8 protons is oxygen, as seen on the periodic table.
What is the atomic number of O?
8Oxygen / Atomic number
How many electrons does an atom with 8 protons have?
Now you can figure out how many electrons, protons and neutrons Oxygen has: Atomic number (which is always the smaller of the two numbers) is 8. Hence 8 protons. Because the atom is neutral, there are also 8 electrons.
What is the element with 8 electrons?
Similarly, neon has a complete outer 2n shell containing eight electrons. These electron configurations make helium and neon very stable.
What is atomic number of an oxygen atom which have 8 electrons and 8 protons?
-Oxygen atoms already had 8 electrons. If 2 more electrons are added to complete the octet of the ion, the total number of electrons becomes 8+2=10. No change occurs in the number of protons because the protons are located in the nucleus of the atom.
What atom has 8 electrons 8 protons and 8 neutrons?
oxygen atom Answer 8: An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999. The atomic number tells you how many protons are in the atom's nucleus.
How many neutrons does oxygen 8 have?
8 neutrons Answer 8: An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999.
What is atomic number of oxygen atom which have 8 electrons and 8 protons?
8 Answer 8: An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999. The atomic number tells you how many protons are in the atom's nucleus.
Why do atoms want 8 electrons?
The rule of 8 or the Octet rule is the tendency of atoms to have eight electrons in their valence shell. Eight electrons in this final shell allow atoms to be stable and non-reactive. Noble gases, for example, are some of the most non-reactive chemical elements one can find in nature.
What element has 8 protons 8 neutrons and 10 electrons?
16O2− has 8 protons, 8 neutrons, and 10 electrons.
What is atomic number of an oxygen atom which has 8 electrons and 8 protons?
D. 8 protons, 8 electrons. Hint: Oxygen atom has the atomic number 8 and it has incomplete octet. Since it belongs to the category of non-metals, it tries to achieve its stable configuration by gaining electrons and so it forms its anion which is called oxide ion.
What is a gas with 8 protons and 8 neutrons?
OXYGEN OXYGEN – I am a gas with 8 protons and 8 neutrons.
How many protons in oxygen if the atomic number is 8?
And this gives rise to the phenomenon of isotopes; i.e. 16O , 17O , 18O ….all of these are oxygen atoms, and so they ALL have 8 nuclear protons, BUT they have 8 , 9 , and 10 neutrons respectively……
Which element has 8 protons 8 neutrons 8 electrons?
Oxygen Oxygen has eight protons, eight neutrons, and eight electrons. Oxygen is different from carbon because it has more particles. Each kind of atom has a different number of the three particles.
What atom has 8 protons and 10 neutrons?
Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and oxygen 18 has 8 protons and 10 neutrons.
What gas has 8 protons and neutrons?
OXYGEN 8. OXYGEN – I am a gas with 8 protons and 8 neutrons.
What is the atomic number of an element with 8 protons?
Oxygen 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.
