All atoms consist of sub-atomic particles. An oxygen atom by itself consists of 8 protons, 8 neutrons, and 8 electrons. Protons, neutrons and electrons are all sub-atomic particles. Protons and neutrons are hadrons, and electrons are leptons. Leptons are elementary particles themselves, but the group known as hadrons (which includes protons and neutrons) are not elementary and are made up of smaller still sub-atomic particles called quarks. In the case of protons and neutrons, they are made of up and down quarks. A proton is made of 2 up and 1 down quark, and a neutron is made of 2 down and 1 up quark.
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
Atom is the basic unit of matter which consists of three sub-atomic particles.
The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
The approximate mass of an oxygen atom in atomic mass units is 16. Oxygen has an atomic number of 8, which means that its atomic mass is approximately 16 atomic mass units.
an atom, protons are one of three sub-atomic particles of the atom
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
Elements (oxygen being one of them) are composed of subatomic particles; that is, protons, neutrons, and electrons. Subatomic particles make up atoms (hence "sub"atomic). Therefore, it is reasonable to say that oxygen is an atom.
Atom is the basic unit of matter which consists of three sub-atomic particles.
The atomic molecule of water is H2O. It consists of two hydrogen atoms bonded to one oxygen atom.
an oxygen and a hydrogen atom do not weight the same
The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
Sub-atomic particles are even smaller particles that make make an atom
Oxygen has an atomic number of 8. This also means that it has 8 protons in its nucleus.
In this case, the number 209 represents the sum of protons + neutrons.
atomicity of oxygen is 2atoms
Oxygen has 8 protons in the atom.
In an atom, no. of protons = no. of electrons=atomic no. no. of neutrons=atomic mass-atomic no.
