THE QUESTION:which letter in the diagram above represents a mountain range in the ocean floor
A.Letter B
B.letter D
C.letter E
D.letter F
THE ANSWER: Based on my research, none of these are truly correct, as A is actually correct. However, I would highly suggests going with B, as it resembles mountains in shape.
The symbol, the atomic mass, the number of protons and electrons
Saturated fatty acids exhibit a linear structure while unsaturated fatty acids bend, or kink, due to double bonds within the chemical foundation.
The answer should be A, flammability.
The isotopes of the same element would result in the same chemical properties, as the number of protons and electrons are not changed, meanwhile, the physical properties would be slightly different with each other because they have different numbers of electrons.
Out of the 4 options, only option A is a chemical property. Chemical properties are the properties of an element reacting with other substances that creates new substances at the end. While physical properties are the ones that does not produces new substances or any reactions. They are usually observable and measurable.
Therefore, since flammability is a chemical property, the answer is A.
Answer:
Electrons arrangement change is almost constant down the group, hence nuclear charge is almost constant.
But the energy levels on which electrons are arranged increase down the group, hence shielding or screening effect increases.
