Which isotope of oxygen is most stable?

Oxygen-16 has 8 protons and 8 neutrons. The proton-to-neutron ratio is equal to 1. Thus, oxygen-16 is the most stable isotope.

How many oxygen atoms are stable?

Oxygen has six valence electrons in its outer shell. Eight electrons are needed to fill the second level to achieve stability. So oxygen needs two more electrons to be stable.

Is H2 stable?

Do they exist? (H2)+ is stable in the gas phase with a bond order of 0.5. However, it is reactive and will rapidly attract an electron to form H2 gas. (H2)- has a bond order of 0.5 as well, but you are adding an electron to the antibonding orbital, which is unfavourable.

Is C2 stable or unstable?

The C2 molecule is a strange beast. It can be identified in the gas phase, but not purified as a compound. So it’s quite unstable.

What are the stable isotopes of oxygen quizlet?

There are three known stable isotopes of oxygen (8O): 16O, 17O, and 18O.

What are the stable isotopes of carbon gizmo?

The next heaviest carbon isotope, carbon-13 (13C), has seven neutrons. Both 12C and 13C are called stable isotopes since they do not decay into other forms or elements over time. The rare carbon-14 (14C) isotope contains eight neutrons in its nucleus. Unlike 12C and 13C, this isotope is unstable, or radioactive.

Which of the following oxygen isotopes is the most common quizlet?

Oxygen-16 is the most abundant isotope of oxygen and accounts for 99.762% of oxygen’s natural abundance.

Is oxygen 17 stable or unstable?

Oxygen-17 atom is the stable isotope of oxygen with relative atomic mass 16.999131. The least abundant (0.038 atom percent) isotope of naturally occurring oxygen.

Is carbon 14 stable or unstable?

Carbon-14 is unstable and undergoes radioactive decay with a half-life of about 5,730 years (meaning that half of the material will be gone after 5,730 years). This decay means the amount of carbon-14 in an object serves as a clock, showing the object’s age in a process called “carbon dating.”

What is the difference between oxygen 16 and oxygen 18?

Oxygen-16 and oxygen-18 differ in the number of neutrons in their nuclei. Oxygen-16 has 8 neutrons, while oxygen-18 has 10 neutrons.

What is a stable isotope?

Stable isotopes are non-radioactive forms of atoms. … While deuterium H-2, an isotope twice as heavy as hydrogen, is predominantly used in nutrition research, nitrogen-15 is the most common stable isotope used in agriculture. Many other stable isotopes are also increasingly being used.

Which radioisotope is the most stable?

A good example of this is tritium, a radioactive isotope of hydrogen naturally present at extremely low levels.

Radioactive Elements.
Element Most Stable Isotope Half-life of Most Stable Isotope
Promethium Pm-145 17.4 years
Polonium Po-209 102 years
Astatine At-210 8.1 hours
Radon Rn-222 3.82 days

How many stable isotopes does ND have?

seven stable isotopes
Periodic Table–Neodymium. Neodymium is a rare earth element (REE) that occurs in many silicate, phosphate, and carbonate minerals by substitution for major ions. It has seven stable isotopes. Nd and samarium (Sm) are considered “light” REEs and become concentrated in feldspars, biotite, and apatite.

Which is more stable O2 or O3?

Hint: The ozone consists of three atoms of oxygen and is in an unstable state. It decomposes into ${O_2}$ molecule with liberation of an enormous amount of heat. … Thus, the formation of oxygen molecules is thermodynamically more stable than ozone molecules.

Is N2 or Cl2 more stable?

Re: Most Stable Forms

All noble gases are most stable in the element phase as a gas. All diatomic gases (such as N2, O2, Cl2, F2, H2, etc.) are the most stable in this gaseous form.

Where is oxygen 16 found?

occurs in three isotopes: 16O (99.763 percent), 17O (0.0375 percent), and 18O (0.1995 percent). Oxygen is found in all organisms and many minerals, including the aragonite and calcite that make up the shells of marine microfossils such as foraminifera.

How many stable nuclei are there?

As of December 2016, there were a total of 252 known “stable” nuclides. In this definition, “stable” means a nuclide that has never been observed to decay against the natural background. Thus, these elements have half lives too long to be measured by any means, direct or indirect.

How many stable isotopes does boron have?

Periodic Table–Boron. Boron has two naturally-occurring stable isotopes, 11B (80.1%) and 10B (19.9%). The mass difference results in a wide range of d11B values in natural waters, ranging from -16 to +59 ‰ (data from references within Vengosh et al., 1994).

Is helium stable or unstable?

Helium atoms, on the other hand, have two protons and two electrons in the lowest energy level. The lowest energy level is filled with its maximum number of electrons. This is a very stable arrangement, and helium in consequence is an inert gas with few chemical properties.

Is oxygen stable or reactive?

Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element. As such, it readily forms compounds (notably oxides) with almost all other elements.

What group of elements is stable?

The noble gases
The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.

Is h22 stable?

For H2, bond order = 1/2 (2-0) = 1, which means H2has only one bond. … Thus, H2 is a stable molecule.

Is Li2 stable or unstable?

Li2 is more stable than Li+2 , because the bond is (hypothetically) stronger (probably gas-phase). for each electron in a bonding MO, it adds 0.5 to the bond order, because more bonding character strengthens the bond…

Is B2 stable?

B2 is a known molecule in gas phase, although not very stable, whose existence has been predicted in terms of MOT because it has a Bond Order greater than zero (in the case of B2, the bond order is 1).
