aIf you study hard, you ___ the examination. 如果您艰苦学习,您___考试。[translate] aHow many neutrons are there in the nucleus of a Th-232 atom 多少个中子那里在Th232原子的中坚力量[translate]
In chemistry, the indication of the total number of protons present in the nucleus of one atom of a chemical element is usually done by their atomic number. The position of the chemical element in the periodic table is also represented by its atomic number...
How many chlorine atoms are in 4.3 grams of phosphorous trichloride? What is the difference between moles and grams? How many hydrogen atoms, which measure 0.1 nm across, will fit across a single caesium atom with a diameter of 0.6 nm ? How many neutrons, protons, and electrons are in ca...
Electricity is flow of electrons (Negative Charge) from one body to another. In order to understand this is some detail, it is important to understand thestructure of an atom. An atom consists of three elements –electrons, protons and neutrons. Electrons are negatively charged (–) particles,...
How many neutrons, protons, and electrons are in carbon? How can I tell if a molecule is polar or non-polar? For a one-electron atom or ion, spin-orbit coupling splits all states except s states into doublets. Why are s states exceptions to this ...
example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called...
These particles, made up of protons and neutrons, are large and can only travel a short distance -- in fact, they can be stopped with just a piece of paper or even your skin. However, inhalation or ingestion of alpha particles can be very dangerous. Once inside your body, alpha ...
