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...
Question: How many electrons are needed to form a charge of -8.30 NC? Quantization of charge: Quantization of charge means that charge on a body is in multiples of the charge on an electron. An electron carries the smallest unit of charge and it equals: {eq}e = -1.6 \times 1...
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,...
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...
How many hydrogen atoms can bind to one carbon atom? How many neutrons are found in one atom of 36Cl? How many carbon atoms are present in 2CO_2 ? How many moles are in 2.16 x 1024 atoms of lead? How many atoms does 32g of sulfur contain? How many atoms of titanium are there ...
A basic hologram is easier to setup than you might think. HowStuffWorks It doesn't take very many tools to make a hologram. You can make one with: A laser: Red lasers, usually helium-neon (HeNe) lasers, are common in holography. Some home holography experiments rely on the diodes fro...
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 ...
