How many protons are there in the C-13 isotope? How many protons and neutrons are in americium-241? How many neutrons does the isotope Ca-42 have? How do you calculate effective atomic number? Is neon-20 an isotope? How many radioactive isotopes are there?
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 10^{-19}...
That is, the individual gas atoms include equal numbers of protons (positively charged particles in the atom's nucleus) and electrons. The negatively charged electrons perfectly balance the positively charged protons, so the atom has a net charge of zero. If you introduce many free electrons ...
To maintain workable diffusion distances, an organism must have many small cells instead of one large cell. So, an alien would be multi-celled if it is larger than a microbe. (We would not expect to find a light-years wide, single-celled organism like that portrayed in the original Star...
A neutral atom is one that has an equal number of protons and electrons. The positive charge of the protons and the negative charge of the electrons will cancel each other out. In the case of argon, it has 18 protons and thus will be neutral if it has 18 electrons in total betwe...
Over time, as the protostar draws in more material and heats up further, things reach a tipping point. When enough mass (think about 0.1 times the mass of our ownsun) collapses into the protostar, it experiences a dramatic and fiery transformation. ...
These energetic electrons and protons initially move past Earth for several thousands of miles before traveling back along Earth’s magnetic field lines into Earth’s atmosphere. Then, through a process similar to a neon sign, they collide with the atoms and molecules of Earth’s atmosphere to ...
What is the oxidation number of fluorine in XeF4? How many electrons are in a Cu2+ ion? How many electrons are in the Mg2+ ion? How many electrons does the Ni2+ ion have? how many electrons are in nitride? How many protons and electrons does each of these ions possess? a. Ag+ ...
years. Largely, it is fused into carbon via the triple-alpha process in which three helium-4 nuclei (alpha particles) are transformed. The alpha process then combines helium with carbon to produce heavier elements, but only those with an even number of protons. The combinations go in this ...
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...
