What on the periodic table has 8 electrons?
So… for the element of OXYGEN, you already know that the atomic number tells you the number of electrons. That means there are 8 electrons in an oxygen atom.
What element contains eight neutrons?
A: Carbon atoms with 8 neutrons have an atomic mass of 14 (6 protons + 8 neutrons = 14), so this isotope of carbon is named carbon-14.
What element or ion has 8 electrons?
Oxygen has the atomic number 8, which means the nuclei of its atoms have 8 protons. A neutral oxygen atom as also has 8 electrons. The oxide anion has a charge of 2− .
What element has has 8 protons and 10 electrons?
O2- indicates an ion of oxygen having two extra electrons. I.e., since an oxygen atom normally has 8 protons and 8 electrons, this ion has 10 electrons (-10 charge) and 8 protons (+8 charge) giving it a charge of -2 (-10 + 8 = -2). Also Know, how many total electrons are in a sr2+ ion?
What element has the most protons?
The heaviest element in nature is uranium, which has 92 protons. But heavier elements-which have more protons in their nucleus-can be created through nuclear fusion.
What gas has 8 protons and 8 neutrons?
Oxygen-16 is composed of 8 protons, 8 neutrons, and 8 electrons. Most 16 O is synthesized at the end of the helium fusion process in stars; the triple-alpha reaction creates 12 C, which captures an additional 4 He to make 16 O. The relative and absolute abundance of 16O is high because it is a principal product of stellar evolution.
Which do elements have more neutrons than protons?
The stable isotopes of the heavier element have a great surplus of neutrons compared to the number of protons. For example the stable isotope of uranium, U_238, has 92 protons and 146 neutrons, nearly a (3/2) to 1 ratio. This may be a matter of that combination involves a lower energy than other combinations of the same number of nucleons.
