What are the two particles called in the centre of an atom?

Protons and neutrons are the two particles found in the center of an atom, known as the nucleus. Protons have a positive charge, while neutrons are neutral.


The nucleus of a helium atom contains four subatomic particles how many neutrons does the helium atom have?

A helium atom has 2 neutrons in its nucleus. This is because the nucleus of a helium atom consists of 2 protons and 2 neutrons, making a total of 4 subatomic particles.


How many proyons and neutrons does a oxygen atom have?

An oxygen atom typically has 8 protons and 8 neutrons in its nucleus.


How would you describe the nucleus of the atom?

the nucleus is the control center of the entire atom the nucleus of an atom has 3 basic subatomic particles: -the electrons which orbit the outside of the nucleus, electrons have a negative charge -the protons which are inside the nucleus and have a positive charge -neutrons which are also inside the nucleus have a neutral charge because they are neither positive nor are they negative something you need to know about protons and neutrons: the mass of the atom equals the protons plus neutrons and the atomic number of an atom tells how many protons are in an atom really being in the nucleus. The nucleus of an atom can best be described as the part of the atom with the biggest mass. It contains an atom's protons and neutrons.


How many protons and how many neutrons in the nucleus of a helium 4 atom?

2 protons and 2 neutron


How many protons and neutrons are in the nucleus of a helium-4 atom if it has twice as many protons as a hydrogen atom?

A hydrogen atom has 1 proton in its nucleus. Since the helium-4 atom has twice as many protons as hydrogen, it has 2 protons. Helium-4 also has 2 neutrons, hence the name "4" representing the total number of protons and neutrons.


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.


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 protons and neutrons does a silicon atom have and where are these two types of subatomic particles located?

A silicon atom has 14 protons and 14 neutrons. Protons are located in the nucleus of the atom along with neutrons. Electrons orbit the nucleus in various energy levels.


Where are neutrons located in an atom and what is the charge?

Neutrons have a neutral electric charge their name comes from this. Neutrons can be found in the nucleus. Most atoms nuclei will have both protons and neutrons in them. Neutrons are responsible for many istopes of elements eg carbon12 has 6 protons and 6 neutrons in its nucleus, and the isotope carbon 14 has 6 protons and 8 neutrons in its nucleus.


What are the locations of the subatomic particles in an atom?

Neutrons and protons are bound together in the nucleus at the center of the atom; electrons occupy various orbitals or energy levels outside and around the nucleus. Neutrons are neutral or have no charge, protons have a positive charge; electrons a negative charge.
