How is the Atom's nucleus held together?
The residual strong force. The strong force (or color force) is what holds quarks together to form protons and neutrons. The residual strong force then holds the protons and neutrons together in the nucleus.
What charge does the electron cloud of every atom have?
In a neutral atom, the charge on the electron cloud is balanced by the carge on the atom's nucleus. The nucleus has a positive charge proportional to the number of protons in it. This attracts and holds the negatively charged electrons in the electron cloud. And in a neutral atom (not an ion), there will be as many electrons in the electron cloud as protons in the nucleus. The charges will balance.
How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
What are the spheres surrounding the nucleus that contains an atom's electrons?
The spheres surrounding the nucleus of an atom are called protons and neutrons, protons hold the electrons in orbit around the nucleus because a proton has a positive charge which attracts the electron which has a negative charge causing electromagnetic force which holds the electron in orbit. The neutron determines the isotope of the atom but has a neutral charge.
In an atom the number of electrons must be the same as the number of?
protons, because the protons are positive and the electrons are negative so to have a neutral atom the protons and electrons must be balanced
What are particles found in an atom besides protons neutrons and electrons?
photons carry the electromagnetic force that holds electrons to the nucleus.mesons carry the strong force that holds protons and neutrons together in the nucleus.W & Z bosons carry the weak force that holds protons and neutrons together in the nucleus and mediate beta decay processes.quarks are inside the protons and neutrons.gluons carry the strong force that holds quarks together inside protons and neutrons.
What does the proton do in the nucleus?
The protons as a collection define the element and the atom. The protons provide the positive force that holds a set number of electrons around the nucleus. In addition, the number of protons determines the element.
What force holds an atom to its nucleus?
its proton and its nucleus will have two protons so its electron and atom
The nucleus of the atom holds the protons and neutrons?
The force between nucleons is called nuclear force.
What is the energy called that attracts the electrons to the nucleus of an atom?
binding energy The attraction force of the positively charged protons in the nucleus binds (holds secure) the negatively charged electrons near the nucleus.
What is the force thea holds an electron to an atom?
The electromagnetic force (protons are positive and electrons are negative, so they attract), which is manifested into Coulomb's force of attraction. The reason that electrons will not fall into the nucleus is due to the electron's energy; it is moving fast enough to not collide with the nucleus.
What indicates the number of an electron in a neutral atom?
Always the Atomic Number = Number of Protons If electrically neutral, Atomic Number = Number of Electrons = Number of Protons
