A carbon-12 atom is defined as having a mass of 12 u. The largest known protein, titin, has a mass of 3 x 106Da. AMU is used to differentiate between isotopes. An atom of U-235, for example, has a lower AMU than one of U-238, since they differ by the number of neutrons in ...
This image shows the carbon-12 atom with its protons and neutrons in the nucleus and the electrons around the nucleus. Carbon-12 atom Based on the scale of AMUs, Carbon-12 is considered to have a mass of 12 AMU. This is because there are 12 nucleons (protons or neutrons), and each...
3、e)nelectrons take up most of the spacenmore protons and neutrons = bigger nucleusnput the following in order of size:qhydride ion (h-)qalpha particle (he nucleus)qhelium atomqhydrogen ion (h+)mass number (copy this slide)nthe total number of protons and neutrons in the nucleus is...
An atom is regarded as the smallest particle of a chemical element that is existing in nature. All substances are made up of either neutral or ionized atoms. The atoms of all elements have three subatomic particles i.e., electrons...
The protons and neutrons make up the small, dense nucleus. The electrons surround the nucleus and occupy most of the volume of the atom. The Atomic Number is the number of protons an atom has. It never changes. In neutral atoms the number of protons equals the number of electrons. Atom ...
1 atomic mass unit is equal to the mass of 1 proton or 1 neutron. 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...
What is the atomic mass of an atom that has 6 protons, 6 neutrons, and 6 electrons? An atom has 20 electrons and 20 neutrons. What is the mass of this atom? What is the atomic mass of copernicium? What does AMU stand for in chemistry?

+ . 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...
