CO2 (one carbon atom bonds with two oxygen atoms) and H2O are an example of heteronuclear diatomic molecules as two different types of atoms bond to form a molecule. Video: What is a molecule? Biology definition: A molecule is the smallest unit of an element or compo...
1.the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound. 2.a quantity of a substance, the weight of which is numerically equal to the molecular weight; gram molecule. ...
and neutrons (hydrogen has 0). An element can has different kinds of atom. In fact they have same no.s of electrons and protons but different no.s of neutron to form a new chemical characteristic. It's called isotope of a element. A mass of an atom is measured by the no...
Diatomic molecules are when only two atoms combine. An example of adiatomic moleculeis carbon monoxide (CO) made of a single atom of carbon and one of oxygen. If the two atoms are the same element, it is called ahomonuclear diatomic molecule, such as oxygen (O2) and nitrogen (N2).Poly...
The concept of the molecule was first introduced into chemistry because of the necessity of distinguishing between the molecule, as the smallest quantity of a substance that takes part in a chemical reaction, and the atom, as the smallest quantity of a given element contained in a molecule (Kar...
Molecule definition: the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.. See examples of MOLECULE used in a sentence.
Chlorine is a fourth element with a high electronegativity. These elements tend to unevenly share or even force a transfer of electrons when they are combined with elements with low electronegativity. What makes a molecule polar? What makes a molecule polar is the uneven distribution of electrons ...

Q. Give one example each of homoatomic triatomic molecule and hetroatomictetra-atomic molecule. Q. Give examples for diatomic and triatomic molecules? Q. Give one example of molecule a triatomic molecule, and a tetra-atomic molecule and an octa-atomic molecule of an element. View More ...
element for nuclear expression (ENE), folds itself into a triple-helical structure that prevents degradation and offers stability (Arun et al., 2018;Chen et al., 2020). Disruption of this spatial arrangement significantly lowersMALAT1levels and could represent a possible therapeutic target in ...
