What helps protons stay together in the nucleus?
The strong nuclear force helps to bind protons together in the nucleus. This force is one of the four fundamental forces in nature and is responsible for overcoming the electric repulsion between positively charged protons.
In order for a heavy nucleus like lead to remain a unit it must have 1.5 times more neutrons than protons to overcome what electrostatic forces?
A heavy nucleus like lead requires more neutrons than protons to overcome the repulsive electrostatic forces between the positively charged protons. These additional neutrons help to increase the strong nuclear force within the nucleus, stabilizing it against the electrostatic repulsion.
What is the number of neutrons protons and electrons in an atom of zirconium 90 that has no overall charge and an atomic number of forty?
In a neutral atom of zirconium-90 with an atomic number of 40, there are 40 protons in the nucleus. Since the atom is neutral, it must also have 40 electrons surrounding the nucleus. To find the number of neutrons, subtract the atomic number from the mass number: 90 (mass number) - 40 (atomic number) = 50 neutrons.
Which of these takes up the most space in an atom?
The thing that takes up the most space of an atom at about 99.99% of the size of the atom is empty space. The majority of the remaining 0.01% is found in the nucleus and about 0.00001% of the atom is taken by the electrons.
How can you calculate the number of electrons in an atom?
The number of electrons in an atom is equal to the atomic number of the element, which determines the number of protons in the nucleus, and thus the number of electrons needed for electrical neutrality. You can find the atomic number on the periodic table.
Is it true that electrons and protons of an atomo are located in the nucleus?
no the only thing located in the nucleus are neutrons and protons. Electrons rotate around the nucleus in orbitals or electron clouds.
Do protons circle the nucles of an atom?
No, Electrons do. Protons do not orbit around the nucleus of atom. It is electron which moves around the nucleus.
What surrounds the protons and the neutrons in an atom?
The protons and neutrons in an atom are the nucleus of it, so the thing that is surrounding it are the electrons.
Is protons the only thing that orbits around the nucleus of an atom?
actually protons exist inside the nucleus not outside. Electrons are the ones that exist outside and they don't orbit they are more like clouds around the nucleus,and nothing orbits the atom's nucleus.
Is electrons the only thing that orbits around the nucleus of an atom?
Electrons are the only elementary particles that orbit around the nucleus of an atom in distinct energy levels or shells. Other particles such as protons and neutrons are located within the nucleus itself.
What three thing make up an atom?
A nucleus containing protons and nuetrons. Also, electrons which are in the electron clouds outside of the nucleus.
What subatomic particles make up an atom and where they are located?
An atom is composed of three subatomic particles: protons, neutrons, and electrons. Protons and neutrons are located in the nucleus at the center of the atom, while electrons orbit the nucleus in various energy levels or shells. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. The number of protons determines the element of the atom, while the number of electrons determines its charge.
What do you think an atom is made of?
All elements are made of protons, neutrons, and electrons. An atom of an element has the same number of electrons as it does protons in it's neutral state. Different elements have a different number of protons. Atoms of the same element can have a different number of neutrons however, and these are known as isotopes.
Why the nucleus of an atom positively charge?
The nucleus only contains neutrons, which are neutral, and protons, which are positively charged. Therefore, the nucleus is positively charged.This is a good thing, since the positive charge is what attracts the negatively charged electrons, otherwise, the electrons would fly free.nucleus of an atom consists of protons and neutrons. protons are positively charged particles while neutrons are neutral. they do not carry any charge on them. however the no. of protons and neutrons remain the same. due to the presence of protons nucleus are always positively chargedthe nucleus contains protons and neutrons only. Since neutrons carry no charge and protons are positively charged, that's why the nucleus is positively charged.
Is the nucleus in an atom positivly or negatively charged?
The nucleus only contains neutrons, which are neutral, and protons, which are positively charged. Therefore, the nucleus is positively charged.This is a good thing, since the positive charge is what attracts the negatively charged electrons, otherwise, the electrons would fly free.nucleus of an atom consists of protons and neutrons. protons are positively charged particles while neutrons are neutral. they do not carry any charge on them. however the no. of protons and neutrons remain the same. due to the presence of protons nucleus are always positively chargedthe nucleus contains protons and neutrons only. Since neutrons carry no charge and protons are positively charged, that's why the nucleus is positively charged.
Is electrons the only thing arranged in various energy levels or orbitals or are protons arranged the same way?
Protons are not arranged in energy levels or orbitals like electrons. Protons are found in the nucleus of an atom and do not occupy specific energy levels or orbitals. Electrons, on the other hand, are arranged in specific energy levels or orbitals around the nucleus.
What would happen to the overall charge if a material with a positive charge lost most of its protons and had more electrons than protons?
Its charge would be negative, since there would be more electrons than protons. However, there is no chemical process that can cause a sudden loss of a bunch of protons from the nucleus of an atom. Alpha decay can cause an atomic nucleus to expel an alpha particle, which consists of 2 protons and 2 neutrons, and there is such a thing as proton decay, but that is extremely uncommon.
