define isodiaphers and isosters
Answers
Answer:
Isosteres are molecules or ions that have a similar shape and often have similar electronic properties. Isodiaphers are atoms with different atomic number and mass number, but with the same difference between the number of neutrons and the number of protons.
Answer: ISODIAPHERS:-In nuclear physics and radioactivity, isodiaphers refers to nuclides which have different atomic numbers and mass numbers but the same neutron excess, which is the difference between numbers of neutrons and protons in the nucleus.
ISOSTERES:-Isosteres are atoms, molecules, or ions of similar size containing the same number of atoms and valence electrons. ... This is a consequence of their identical electron arrangements. The term isosteres is not frequently heard in chemistry; the term bioisostere is commonly used in drug development.
