I'm pretty sure it's A, but then again I'm only in 8th grade. Sorry if this doesn't help:(
We generally represent an element by its symbol. provided with the atomic number and mass number or atomic mass
Atomic number is the number of protons present in an element. It is constant for an element.
The mass number of element is the sum of number of protons and number of neutrons
The atomic mass is the total mass of all the protons and neutrons present in the element (in its nucleus).
the number of electrons is equal to number of protons in a neutral atom of element.
The mass of electrons is not included in the total atomic mass of element as it is very low.
So here
12 = it is the number of protons = atomic number of element.
The true statements are
The combined mass of protons and neutrons is 24.305
Answer : The correct option is B (clay, slit, sand).
Explanation :
Soil particles are of three types : Sand, Slit and clay. Most of the soils particles are made up of a combination of sand, slit and clay.
Particle size range of the sand = 2.00 -0.05 mm
Particle size range of the slit = 0.05 -0.002 mm
Particle size range of the sand = less than 0.002 mm
Sand is the largest soil particle, clay is the smallest soil particle and slit particle is present in between the sand & clay particle.
Therefore, the order from smaller to larger sediment particles is
Clay > Slit > Sand
Answer:
Answer is B
