Chemical isomers: compounds with the same chemical composition but with a different structure.
Nuclear isomers: isotopes having different half lives.
Isotopes: atoms having a different number of neutrons in the atomic nucleus.
Polymers: compounds formed from many monomers.
Molecule: an entitity formed from two or more atoms linked by chemical bonds.
What else can I help you with?
Why do isomers exhibit variations in their boiling points?
Isomers exhibit variations in their boiling points because of differences in their molecular structures, which affect the strength of intermolecular forces between molecules. These forces determine how easily a substance can transition from a liquid to a gas state, leading to differences in boiling points among isomers.
How many isotopes does Curium have?
Curium has 20 isotopes and 7 isomers.
What molecules are identical in chemical composition but differ in structure?
hydrocarbons, they are called isomers
How many isotopes does the element seaborgium have?
Seaborgium (Sg) has 17 isotopes - including isomers and metastable isotopes.
How many isotopes does americium have?
Americium has today (2011) 19 isotopes and 8 isomers.
Is it true that atoms with the same number of protons but diffrent numbers of neutrons are called isomers?
Not isomers, Isotopes
How many isotopes does radium have in its nucleus?
Radium has today 33 isotopes and 12 nuclear isomers.
What physical properties are different for the isomers. explain.?
Isomers are molecules with the same molecular formula but different structural arrangements. Physical properties that can differ between isomers include boiling points, melting points, solubility, and density. These differences arise because the arrangement of atoms in isomers affects how the molecules interact with each other, leading to variations in physical properties.
What is the difference between monomers and isomers?
Monomers and isomers are completely different. Monomers are building blocks of polymers/macromolecules. For example, amino acids are the monomers of proteins and monosaccharides are monomers of carbohydrates. Isomers, on the other hand, are molecules with the same number of atoms in a compound, but different arrangements of bonds or shapes.
How many isotopes does chromium have?
Chromium has 25 known isotopes, 2 isomers, 3 of which are non-radioactive.
Is francium an isotope?
Francium has approx. 40 isotopes and nuclear isomers.
How can one determine constitutional isomers?
Constitutional isomers are molecules with the same molecular formula but different connectivity of atoms. To determine constitutional isomers, compare the arrangement of atoms in the molecules and look for differences in how the atoms are bonded together. If the connectivity of atoms is different, the molecules are constitutional isomers.
