- Hydrogen.
- Nitrogen.
- Oxygen.
- Fluorine.
- Chlorine.
- Bromine.

What is group 17 on the periodic table called?
halogen
halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
Is Phosphorus a diatomic?
Helium is considered monoatomic because it has 1 atom in its molecule, but hydrogen is considered diatomic because it has 2 atoms of hydrogen in its molecule. Ozone is considered triatomic because it has 3 atoms of oxygen, but phosphorus is considered tetratomic because it has 4 atoms in its molecule.
What are the six monatomic elements?
The noble gases are the examples of monatomic gases, and they are:
- Helium.
- Radon.
- Neon.
- Xenon.
- Argon.
- Krypton.
What are the 9 diatomic elements?
The elements found as diatomic molecules are hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), chlorine (Cl, element 17), bromine (Br, element 35), and iodine (I, element 53).
Why is chlorine in group 17?
It is a nonmetal, and is one of the few elements that can form diatomic molecules (F2). Chlorine is a halogen in group 17 and period 3. It is very reactive and is widely used for many purposes, such as as a disinfectant. Due to its high reactivity, it is commonly found in nature bonded to many different elements.
Is carbon a diatomic?
Diatomic carbon is a diatomic molecule of carbon (C2), which occurs when in an electric arc (along with some buckyballs), in comets, and in the blue light we see in flames.
Is chlorine a diatomic element?
Diatomics on the Periodic Table. The 7 diatomic elements are hydrogen (H), nitrogen (N), oxygen (O), fluorine (F), chlorine (Cl), bromine (Br), and iodine (I). We call them diatomic elements because the atoms appear in pairs.
Is chlorine a monatomic element?
Elements that form stable homonuclear diatomic molecules at standard conditions (STP) are hydrogen gas (H2), nitrogen gas (N2), oxygen gas (O2) and chlorine gas (Cl2). The noble gases (like krypton, xenon, radon and other) are gases also stable at STP, but they exist as monatomic elements in nature.
Is carbon a monatomic element?
Monatomic – composed of one atom e.g. He, Ni, Ar, Kr (all noble gases are monatomic) Diatomic – composed of two atoms e.g. H2 , N2 , O2 , F2 , Cl2 (all halogens are usually diatomic)…Examples.
| Atomic Number | Element | Atomicity |
|---|---|---|
| 6 | Carbon (C) | 1 |
| 7 | Nitrogen (N) | 2 |
| 8 | Oxygen (O) | 2 |
| 9 | Fluorine (F) | 2 |
What are the 6 groups of the periodic table?
Group 6, numbered by IUPAC style, is a group of elements in the periodic table….Group 6 element.
| Z | Element | No. of electrons/shell |
|---|---|---|
| 24 | chromium | 2, 8, 13, 1 |
| 42 | molybdenum | 2, 8, 18, 13, 1 |

What are the 3 main groups of the periodic table?
The three major groups on the Periodic Table are the metals, nonmetals and metalloids. Elements within each group have similar physical and chemical properties.
What is fluorine?
Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium .
What is the atomic number of fluorine?
Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas.
What is the common name for chlorofluorocarbon?
Chlorofluorocarbon. Chlorofluorocarbons ( CFCs) are fully halogenated paraffin hydrocarbons that contain only carbon (С), chlorine (Cl), and fluorine (F), produced as volatile derivative of methane, ethane, and propane. They are also commonly known by the DuPont brand name Freon.
What is carbon fluorine used for in everyday life?
Molecules containing a carbon–fluorine bond often have very high chemical and thermal stability; their major uses are as refrigerants, electrical insulation and cookware, the last as PTFE (Teflon). Pharmaceuticals such as atorvastatin and fluoxetine contain C−F bonds.
