Atoms that are good conductors typically have low ionization energy, allowing their outer electrons to move freely. Additionally, good conductors often have partially filled d or f orbitals, which promote easy electron movement. Metals, such as copper and silver, are known for their excellent conductivity due to these factors.
It is the energy band gap which determines whether a material is a conductor , semiconductor or insulator. One of the fascinating yet basic wonder of solids. Its all because of the arrangement of electrons in different energy levels while crystallization. Need further explanation refer solid state physics by S.O.Pillai
Neutrons are used to determine the mass of an atom. By adding the number of protons and neutrons together, the atomic mass of an atom can be calculated.
They are on the outside of the atom. (Apex 2021)
The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.
Valence electrons
Number of protons or the atomic number of an atom determines what is the element.
No. The wavelength of the light determines whether an electron will be ejected from an atom.
the silicon is the insulator
A conductor
Conductors are substances where electrons can freely move from atom to atom.
Only in hydrogen or helium, because in these two elements only the innermost shell is also the outermost shell.
To determine if an equation is balanced, compare the number of each type of atom on the reactant side to the product side. Make sure there is an equal number of each type of atom on both sides of the equation. If the number of atoms is balanced, the equation is balanced.
A cation is formed when an atom loss electrons.

No, having four valence electrons does not determine whether an atom is an anion. An anion is formed when an atom gains electrons to have a negative charge. If the atom with four valence electrons gains four more electrons, it would become an anion.
The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.
