On the periodic table it is the number on the bottom of the element.
<span>If you know the amount of neutrons you can add it to the number of protons to find the atomic mass NUMBER, which is a good approximate of the atomic mass. </span>
Answer:
Harmony is correct, because Mendeleev’s model made predictions that came true.
Explanation:
Mendeleev published periodic table.
Mendeleev also arranged the elements known at the time in order of relative atomic mass, but he did some other things that made his table much more successful.
Our answer is : Harmony is correct, because Mendeleev’s model made predictions that came true.
The answer is C.
Smoke is defined as a colloid, which is any substance consisting of particles substantially larger than atoms or ordinary molecules. It is a suspension of solid and or liquid particles in the air.
The most likely mode of decay for a neutron-rich nucleus is one that converts a neutron into a proton.
<h3>What is radioactive decay?</h3>
The process through which an unstable atomic nucleus loses energy through radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration. A substance that has unstable nuclei is regarded as radioactive. Alpha decay, beta decay, and gamma decay are three of the most frequent kinds of decay, and they all entail the emission of one or more particles. Beta decay is a result of the weak force, while the nuclear force and electromagnetism are in charge of the other two mechanisms. The capture of an inner electron from one of the electron shells by an unstable nucleus is the fourth prevalent form of decay.
