The atomic mass is equal to: A. the number of neutrons. B. the number of protons plus the number of electrons. C. the number of protons plus the number of neutrons. D. the number of electrons. E. the number of protons. How ...
How many neutrons does element x have if it's atomic number is 42 and it's mass number is 154? How many neutrons are found in an isotope of Carbon-14? How many neutrons does element X have if its atomic number is 43 and its mass number is 161? A certain atom has an atomic...
Neutron stars are the remnants of massive stars that collapsed at the end of their lifetimes, compressing more than a Sun’s worth of mass into a dense ball of neutrons just 20 kilometres or so across. Occasionally, neutron stars orbit each other in pairs, or binaries. If their orbit is ...
Along with the United States and Canada, Spain and Russia also have instruments on the mission. Spain is studying the Rover Environmental Monitoring Station, designed to survey the atmosphere and ultraviolet rays. Russia supplied the Dynamic Albedo of Neutrons instrument, which measures hydrogen below...
The periodic table of elements includes 118 individual types of atoms (that is, elements), all of which have a unique number of protons and electrons and a similar number of neutrons. But just how tiny is this infinitesimally small entity? Is there a way to relate thesize of an atomto ...
Ambient light - Ambient light is light that has bounced and scattered in many directions so that it is does not seem to have a specific source. A good example of ambient light is the glow in the sky around a major city. It would be very hard to identify a single source of light for...
The protons and neutrons in the nucleus are held together very tightly. Normally the nucleus does not change. But some of the outer electrons are held very loosely. They can move from one atom to another. An atom that loses electrons has more positive charges (protons) than negative charge...
For example, carbon atoms always have six protons; hydrogen atoms always have one; and oxygen atoms always 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 ...
