The band of stability in chemistry refers to the range of stable isotopes on a graph of the number of neutrons versus the number of protons in atomic nuclei. Isotopes within this band are more stable because they have a balanced ratio of neutrons to protons. Nuclei outside of this band may undergo radioactive decay to become more stable.
In chemistry, "da" stands for Dalton, a unit used to measure atomic mass. It represents the mass of one atomic particle, which is approximately equal to the mass of a proton or neutron. The atomic mass of an element is measured in Daltons, which helps scientists determine the relative mass of different atoms and molecules.
Shared: Electrons in a covalent bond are shared between the two nuclei.
The Big M in chemistry represents molar mass, which is the mass of one mole of a substance. It is significant because it helps in calculating the molecular weight of a compound by adding up the atomic masses of all the elements in the compound. This is important for determining the amount of a substance needed in reactions and understanding its properties.
In chemistry, a period is a horizontal row in the periodic table that represents the number of electron shells an atom has. Each period corresponds to the energy levels of an atom's electrons. The organization of elements in the periodic table is based on their atomic number and electron configuration, with elements in the same period having similar properties due to their electron arrangement.
Most physical and chemical characteristics of a substance relate to the nuclei's neutron-proton composition. The number of protons in a nucleus is the atomic number (Z) and establishes the chemical identity of the atom. Each atomic number corresponds to a different chemical element; there are now approximately 106 known chemical elements that correspond to nuclei containing from 1 to 106 protons.

For example in the investigation of poisoning.
transistor are materials they have to be extracted and purified this relies on chemistry and material science
The atomic number of helium is 2. This number indicates the number of protons in the nucleus of a helium atom. The atomic number of an element determines its chemical properties, such as its reactivity and bonding behavior. Helium's atomic number of 2 means it has a stable configuration, making it a noble gas with low reactivity and high stability.
Transistors are made of materials. They have to be extracted and purified. This relies on chemistry and Materials Science.
The wine alcohol is related to chemistry, because one of the chemicals in organic chemistry is used in making it:ethanol.
