The mass of one atom of titin (the largest known protein) = 3 x 106 AMU Each 12C atom has six protons and six neutrons in its nucleus, adding up to an atomic mass of 12 AMU. Electrons have a low mass, so they are assumed to have a negligible effect. Consequently, the nucleus acco...
AMU, it roughly reflects the sum of the number of protons and neutrons in the atomic nucleus (electrons have so much less mass that they are assumed to have a negligible effect). The symbol for the unit is u (unified atomic mass unit) or Da (Dalton), although AMU may still be used....
The atomic mass unit is defined as one-twelfth the mass of a carbon-12 atom. Carbon-12 has 6 protons and 6 neutrons in its nucleus and has a mass of 1.99×10−23g. This image shows the carbon-12 atom with its protons and neutrons in the nucleus and the electrons around the nucleus...
+ . it is an antiparticle called antielectron. its mass is the same as the mass of an electron. electrons, protons, and neutrons are known as the fundamental particles of atoms. electrons are placed in certain orbits surrounding the nucleus. protons and neutrons are placed within the nucleus...
An atomic mass unit is defined as 1/12 the mass of a carbon-12 atom. A carbon-12 atom has 6 protons and 6 neutrons. Therefore, each proton and neutron is approximately 1 AMU. How do you convert AMU to kg? In order to convert atomic mass units to kilograms, the conversion must be...
