Are nuclei held together by electrical forces?

The salt NaCl is indeed held together by coulombic (electrostatic) attraction, in addition to atomic forces holding the nuclei together.

Radioactive substances consist of nuclei that can't be held together by the strong force.

I am not entirely sure what you mean; lots of things within the Universe (the Solar System, galaxies, galaxy clusters) are held together by gravity. Molecules are held together by electric forces; atomic nuclei are held together by the "strong force".

Delocalized valence electrons moving between nuclei become detached from their parent atom. The metal is held together by the strong forces of attraction between the delocalized electrons and positive nuclei.

Substances held together by physical forces, not chemical

Atoms are held together by electric charge, nuclei are held together by the strong nuclear force, molecules are held together my electric charge, the Earth's particles are held together by "gravity."

Atoms are held together by strong electrostatic forces.

An element is held together by strong atomic forces.

the atom is held together by nuclear forces known as the electromagnetic force

The atoms of a molecule are held together by forces of attraction called intermolecular forces. Three types of intermolecular forces are ionic, covalent and metallic.

The air particles are held together by the van der Waals forces of attraction.

electrons are held to nucleus by electromagnetic force. protons and neutrons in nucleus are held together by both strong and weak forces. quarks in protons and neutrons are held together by strong force.

The nucleus is held together by a combination of both the strong and weak forces. The electrons are held in their orbitals about the nucleus by the electromagnetic force. That leaves only gravity, which does not participate in holding atoms together.

atoms's sub-particles electron neutron and proton are held together by very strong nuclear force if we supply energy enough these forces tend to break and along with disintegration of atoms it releases lot of energy. nuclear energy comes from breaking these forces by the methods of fission(breaking the particle from large nuclei to small nuclei) while fusion (combining two small nuclei into bigger nuclei of atoms) energy produced in fusion is much larger as compared to fission

Yes, these intermolecular forces are exist, as an example hydrogen bonds.

The atoms in a water molecule are held together by covalent bonds. The intermolecular forces holding molecules of water together are hydrogen bonds.

Stars are held together only by the force of gravity. The other 3 fundamental forces have no influence on that.

Atoms are held together by a few forces, depending on how small you look. Quarks (the sub-atomic particles that make up protons and neutrons) are held together by gluons. Protons and neutrons are held together by the strong nuclear force. The nucleus and electrons are held together by the electromagnetic force.

They are held together by strong electrostatic forces caused by the attraction between negative and positive charges.

DNA strands are held together by Van der Waals forces. The nitrogen bases located on the strands are held together by hydrogen bonds.

They are held together by forces. For more info go to bbc bitesize

False Neutrons and PROTONS are held together by strong nuclear force Electrons arent held to the neutrons at all

Molecules are held together by covalent bonds. These may be polar or non-polar. Crystals may be ionic, held together by electrostatic forces (Coulomb forces) or be network covalent such as diamond or silicon dioxide.

Atoms are held by interatomic forces. It bind the atoms together.

There are 4 types of forces: gravity, electromagnetic, strong, and weak. Atoms are held together by electromagnetic forces, the nucleus is held together by the strong force. The nucleus contains neutrons and protons which are made up of quarks, which are held together by a type of strong force called a gluon.
