An anti-hermitian (and skew-hermitian) operator is equal to minus its hermitian conjugate: (a) Show that the expectation value of an anti-hermitian operator is imaginary. (b) Show that the eigenvalues of an anti-hermitian operator are imaginary. (c) Show that the eigenvectors of an anti-hermitian operator belonging to distinct eigenvalues are orthogonal. (d) Show that the commutator of two hermitian operators is anti-hermitian. How about the commutator of two anti-hermitian operators

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

answer: 40392

step-by-step explanation:

10098 x 4 = 40392
