So, when two different air masses meet, a boundary is formed. The boundary between two air masses is called a front. Weather at a front is usually cloudy and stormy. There are four different fronts- Cold, Warm, Stationary, and Occluded.
Atomic number is written in subscript:
Uranium atomic number =92
Mass of neutron is the superscript value times the quantity (moles):
3*1= 3
Atomic mass is approximately equivalent to the number of protons and neutrons in the atom (the mass number). It's written in superscript:
Kr=92
No. of neutrons = Mass number (in superscript) - Atomic number ( in subscript)
= 141-56= 85
No. of neutrons in reactants are: 3
Answer: Physical properties of matter include color, hardness, malleability, solubility, electrical conductivity, density, melting point, and boiling point. For the elements, color does not vary much from one element to the next
n = 5
l = 0,1,2,3,4
ml = -4,-3,-2,-1,0,1,2,3,4,
ms = +1/2 and -1/2
