Fluorine (18.994-9=10 neutrons
) and Neon (20.180-10=10 neutrons)
Number of neutrons = Atomic mass - Atomic number So Fluorine = 19- 9 = 10 and Neon = 20-10 = 10 :)
Oxygen-18, fluorine-19 and neon-20 atoms have 10 neutrons each.
All oxygen atoms contain 8 protons in their nuclei. All neutral oxygen atoms have 8 electrons. There are three isotopes of oxygen, containing 8,9, or 10 neutrons in their nuclei.

10 protons, 12 neutrons
(Explanation): remember that if an atom has less than 20 protons, the closer the number of neutrons and protons are, the more stable it is. Since 10 is closest to 12 out of these options, D is the correct answer.
Boron has two stable isotopes, Boron-10 and Boron-11, because they have different numbers of neutrons in their nuclei. Boron-10 is used in nuclear reactors and shielding due to its ability to absorb neutrons. Boron-11 is an essential element in many industries, including electronics and aerospace, due to its unique properties.
Neutrons have no electric charge and have nearly 1,840 times the mass of the electron. Free neutrons undergo beta decay with a half-life of about 10 minutes. Thus, they are not readily found in nature, except in cosmic rays. They are a penetrating form of radiation. When bombarded with neutrons, various elements undergo nuclear fission and release more free neutrons. If enough free neutrons are produced, a chain reaction can be sustained.
Neon, and certain isomers of other elements.
fluorine and neonAdded:To my best knowledge there are 3 naturally occurring isotopes with 10 neutrons: 8O(18) (0,2%),9F(19) (100%),10Ne(20) (91%),And additionally: only 12Mg(22) which is artificial and not stable (radio isotope).
Oxigen has 8 protons; natural isotopes have 8, 9 an 10 neutrons.
Neutrons have size (about 10-13 cm in diameter) and mass (1.6749 x 10-27 kg).
