How do you figure out neutrons?
Take note that the nucleus of an atom is composed of protons and neutrons. And the number of particles present in the nucleus is referred as mass number (Also, called as atomic mass). So, to determine the number of neutrons in atom, we only have to subtract the number of protons from the mass number.How many neutrons does nitrogen have?

Is mercury a liquid?
Mercury is the only metal that is a liquid at normal temperatures and pressure. Because of the behavior of the valence electrons, mercury has a low melting point, is a poor electrical and thermal conductor, and doesn't form diatomic mercury molecules in the gas phase.What is Mercury's family?
Mercury (Hg), also called quicksilver, chemical element, liquid metal of Group 12 (IIb, or zinc group) of the periodic table.What's the number of mercury?

Who discovered Mercury?
Mercury is one of the five classical planets visible with the naked eye and is named after the swift-footed Roman messenger god. It is not known exactly when the planet was first discovered - although it was first observed through telescopes in the seventeenth century by astronomers Galileo Galilei and Thomas Harriot.What is the number of electrons in Mercury?
2,8,18,32,18,2
Why is mercury dangerous?
This liquid form of mercury is especially dangerous because it vaporizes at room temperature. If mercury vapor is inhaled, it is easily absorbed by the body, where it first gets into the lungs and from there into the blood and the brain. The nerve poison can cause sleep disorders, agitation, and paralysis.How many neutrons are in Mercury 200?
120 neutrons
What is atomic mass number?
The mass number (symbol A, from the German word Atomgewicht [atomic weight]), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. The mass number is different for each different isotope of a chemical element.How do you find electrons in an ion?
The charge on the ion tells you the number of electrons. If the charge is positive, subtract that number from the atomic number to get the number of electrons. You have more protons. If the charge is negative, add the amount of charge to the atomic number to get the number of electrons.How much does Mercury cost?
Cost: The cost of pure mercury is $48 per 100g. And the cost of mercury in bulk is $1.74 per 100 grams. Fun Facts: -Mercury is actually very poisonous and can potentially kill people.How do you find the number of electrons?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).What is the last element in Period 4?

Which is more radioactive U 235 or U 238?
The U-238 nucleus also has 92 protons but has 146 neutrons – three more than U-235 – and therefore has a mass of 238 units. The difference in mass between U-235 and U-238 allows the isotopes to be separated and makes it possible to increase or "enrich" the percentage of U-235.Is uranium 235 dangerous?
Because uranium decays by alpha particles, external exposure to uranium is not as dangerous as exposure to other radioactive elements because the skin will block the alpha particles. Ingestion of high concentrations of uranium, however, can cause severe health effects, such as cancer of the bone or liver.Why is U 235 better than u 238?
U- 235 is a fissile isotope, meaning that it can split into smaller molecules when a lower-energy neutron is fired at it. U- 238 has an even mass, and odd nuclei are more fissile because the extra neutron adds energy - more than what is required to fission the resulting nucleus.Why is U 238 not used as a fuel?
Uranium 238 is not fissionable by thermal neutrons, but it can undergo fission from fast or high energy neutrons. Hence it is not fissile, but it is fissionable. For U-235, if it absorbs a thermal neutron, the binding energy released is greater than the critical energy required for fission and so it is fissile.
