Explanation:
Crystallography. an arrangement in space of isolated points (lattice points ) in a regular pattern, showing the positions of atoms, molecules, or ions in the structure of a crystal.
If an atom experiences sufficient thermal activation, it can move to a neighboring lattice position.4 If the vibration frequency of the atom is v and the atom has Z nearest neighbors, the total number of jump attempts is vZ. However, only a small fraction of the attempts will be successful, with a probability depending on the ratio between the necessary activation energy for a single jump QD and the thermal activation kBT. The effective jump frequency ΓD is then
(5.6)
With each successful jump, the atom travels one atomic distance λ and the total traveling distance in unit time is thus ΓDλ. Substituting the jump frequency ΓD into the expression for the root mean square displacement of a random walker [equation (5.5)] and using the spatial coordinate r leads to
Chemical properties of elements are primarily determined by the electrons but not by the neutrons. Therefore, Isotopes can have different number of neutrons and electron,but not protons
Answer:
A = 8
B = 8
C = Oxygen (O)
D = 26
E = 30
F = Iron (Fe)
Explanation:
protons neutrons atomic number mass number element
A 7 B 15 C
D E 26 56 F
mass number = protons + neutrons
E = 56 - 26 = 30
A = 15 - 7 = 8
protons = atomic number
B = 8
D = 26
From atomic number:
C = Oxygen (O)
F = Iron (Fe)
A compound differs from an element in that it can be decomposed by a chemical reaction.
A compound, by definition, is made up of two or more elements that have been combined together through a chemical bond.
Thus, the chemical bond or bonds in a compound can be decomposed by a chemical reaction giving rise to the individual elements that make up the compound.
This is unlike an element that can not be decomposed by any chemical reaction.
