Answer:
Orbital designation
for Principle Quantum number n=4, this is the shell number & corresponds to N shell, (shells are designated K,L,M,N)
for Angular Momentum number l=2, this is the orbital level corresponding to d, given that l can be any integer 0-(n-1), for( 0,1,2,3 )corresponds to (s, p, d, f)
The orbital designation is 4d
for Magnetic Quantum number ml, the suborbitals correspond to -l through l, (-2,-1,0, 1,2)
for ml=-1 the suborbital -1 in the 4d sub shell with electron spin state ms=-1/2
The ocean is very interesting. There is so much of it on earth. There’s ocean nobody has seen. It’s crazy. I can study this by learning about the ocean and maybe going to the beach
Answer:
D
Explanation:
Diabetes is caused when the pancreas has trouble producing insulin, a hormone that lowers blood sugar levels. Since the endocrine system deals with hormones, diabetes is an endocrine system disease.
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses. Mass is the word for how much substance (or matter) something has.
Isotopes are atom families that have the same number of protons, but different numbers of neutrons
Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
Answer:To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23
