Answer:
Thermal expansion is the tendency of matter to change its shape, area, and volume in response to a change in temperature.
Explanation:
Answer;
e. Electronegativity of an atom is it's ability to attract electrons during bond formation.
Explanation;
The electronegativity of an atom or element is a chemical property that describes the strength of attraction for more electrons by that atom.
-The protons of an atom will always have an attraction for electrons.
-Some atoms because of the electron configuration have more attraction than other atoms. While other atoms have very little attraction for electrons. Non metals generally have high electronegativities because they have an electron configuration that requires more electrons to be stable.
Answer:
have the same molecular formula and coordination number
Explanation:
Coordination sphere isomers refer to two or more coordination compounds which have the different compositions within the coordination sphere (i.e., the metal atom plus the ligands that are bonded to it) i.e., the connectivity between atoms is different.
Let us show a typical example;
[Cr(NH3)5(OSO3)]Br and [Cr(NH3)5Br]SO4
The molecular formula and coordination number of the both compounds are the same but atom-atom connections differ. In one compound, sulphate ion is outside the coordination sphere while in its isomer, the sulphate ion is inside the coordination sphere.
