The answer depends on the atom! The total number of subatomic particles in an atom of an isotope is the sum of the mass number and the atomic number of the isotope; the mass number counts the protons and neutrons together, and the atomic number recounts the number of protons, which in a neutral atom must be the same as the number of protons.
What else can I help you with?
What particles are never present in an atom?
Particles that are never present in an atom include free electrons (outside the nucleus), neutrinos, and positrons. These particles do not form part of the structure of the atom itself.
What is the total number of subatomic particles in the nucleus of an atom bi?
In this case, the number 209 represents the sum of protons + neutrons.
What is the total number of subatomic particles in one atom of scandium?
One atom of scandium typically contains a total of 45 subatomic particles - 21 protons, 24 neutrons, and 21 electrons.
Which particles account for the difference between the atomic number and the mass number?
The answer is that it is neutrons that account for the difference between atomic weight and atomic number. The atomic number is the number of protons or the number of electrons in the atom, since they are normally equal. The atomic weightis the sum of the total number of protons, electrons AND neutrons in the atom. Knowing both the atomic number and the atomic weight of an atom lets you know the number of neutrons in the atom (the isotope). Example: Uranium, Atomic Number 92, Atomic Weight 235. The atomic number tell you that the uranium atom has 92 protons and 92 electrons. The atomic weight tells you that it has a combined total of 235 protons, electrons and neutrons. Since you know from the atomic number that there is a total of 184 protons and electrons in the atom (92 + 92) and from the atomic weight that the total number of protons, electons and neutrons is 235 (92 + 92 + X = 235), you now know that there are 151 neutrons in that uranium atom. The atomic number and atomic weight together tell you that the uranium atom 235 has 92 protons, 92 electons and 151 neutrons.
What must be true of the number of protons and the number of electrons in an atom if the atom has no charge?
The number of protons must equal the number of electrons in an atom for it to have no charge. Protons are positively charged particles, and electrons are negatively charged particles. A balanced number of protons and electrons results in an atom with a neutral overall charge.
Protrons are particles that are?
Protons are the positively charged particles that are present in the nucleus of the atom and their number determines the atomic number of the atom.
What are the particles that make a atom including the atomic number and mass number?
The atomic number is the number of protons in an atom (which equal the number of electrons present) The atomic mass is the number of protons+neutrons in an atom
Total number of particles in the nucleus is called what?
There are two types of particles in the nucleus of an atom, which are the Protons and the Neutrons. The number of particles in the nucleus depends what is the element. For example, Oxygen has 8 protons and 8 neutrons in the nucleus and Phosphorus has 15 protons and 16 neutrons in the nucleus.
What particles are never present in an atom?
Particles that are never present in an atom include free electrons (outside the nucleus), neutrinos, and positrons. These particles do not form part of the structure of the atom itself.
What is the total number of subatomic particles in the nucleus of an atom bi?
In this case, the number 209 represents the sum of protons + neutrons.
How many particles are located inside the nucleus of an atom?
The nucleus of an atom contains protons and neutrons, which are collectively referred to as nucleons. The number of particles inside the nucleus varies depending on the element, as it is determined by the number of protons and neutrons present.
How many subatomic particles are present in an atom except proton neutron electron and what are they?
The only subatomic particles that exist in an atom are protons, neutrons, and electrons.
What is the total number of subatomic particles in one atom of scandium?
One atom of scandium typically contains a total of 45 subatomic particles - 21 protons, 24 neutrons, and 21 electrons.
How many particles are in the nucleus of an atom of xenon?
For an atom of xenon, the number of particles in the nucleus would be the sum of the protons and neutrons. Xenon has 54 protons and usually around 78 neutrons, so the total number of particles in the nucleus would be around 132.
What is the number of subatomic particles are in an atom?
An atom contain protons, neutrons and electrons. The number of these particles is different for each isotope.
What is the total number of atoms present in the molecule CH3NH2?
The total number of atoms present in the molecule CH3NH2 is 7. This includes one carbon atom, four hydrogen atoms, and two nitrogen atoms.
What is the total number of atom present in hydrogen chloride?
It depends on how many molecules of HCl you have. In one molecule of HCl there are 2 atoms present.
