When a metal has electrons that are not tightly held together by any one atom in the crystalline structure it is generally a good conductor of electricity. This is because as current moves into the metal electrons are free to flow and move through the metal. This is the definition of a conductor.

The valence electrons are those electrons most tightly held by the atom?
Atoms with 8 valence electrons are highly stable and almost non-reactive. There electronic configuration is stable. In the normal state, only noble gases have this electronic configuration except Helium which has only 2 electrons.
How do the outer electrons in metal atoms differ from the outer electrons in nonmetal atoms?
Those electrons are called the valence electrons. They are the ones that can be transferred and form bonds with other atoms.
Does the ability of atoms to conduct electricity have to with loosely held electrons?
Electrons shared between atoms.
Is a group of atoms held tightly?
It depends on different types of matter !!!!!!
The metal atoms in aron are held together by?
If you think to the metal iron - a metallic bonding exist.
What kind of matter is electricity?
Electricity is the movement of electrons. In metals, which are good conducters of electricity, electrons are "delocalised", which means that they are not held tightly by the nuclei of the metal's atoms, and are free to flow from the negative end of, say, a circuit with a metal wire, to the positive end.

Does whether or not charges will move in a material depend partly on how tightly they are held in the atoms of the material?
It depends on whether the charges are free to move. There are two ways in which charge can move through a substance. Ionic substances are made of positive and negative ions. In a solid they have fixed positions, but in liquids and gases they can move around. Ions are atoms (or groups of atoms) which have gained or lost electrons. How tightly their electrons are held has no effect here as it's the whole ion which moves. The second situation where charges can move is when electrons are in delocalized bonds. In most substances the electrons are in orbitals associated with one atom or a small group of atoms. In metals, some electrons are in large orbitals which are shared by all the atoms, so the electrons (which are charged) can move freely through the whole metal. In this situation, the delocalized electrons can be thought of as not held by individual atoms, but they are still held by the assemblage of atoms. So the assertion in the question has elements of being right, but it's not the degree to which the electrons are held, but whether or not they are delocalized.
How are atoms held together in a in solid potassium metal?
imagine the metal as a "sea", where all of the electrons in the metal are freely flowing throughout the entire substance. the flow of these electrons if what holds them together.
What is it that atoms of materials that conduct electricity best tend to be held together by?
Atoms of materials that conduct electricity best tend to be held together by metallic bonds. This is the attraction between positively charged nuclei in metal atoms and the delocalized electrons in the metal.
Matter in which atoms are tightly held in place is a?
a solid
What is matter in witch atoms are tightly held in place?
Solid
How do the outer electrons in metal atoms differ from the outer electrons in nonmetal atoms?
Those electrons are called the valence electrons. They are the ones that can be transferred and form bonds with other atoms.
What is atoms held together by sharing electrons?
Covalent bonds are created when atoms share electrons.
Does the ability of atoms to conduct electricity have to with loosely held electrons?
Electrons shared between atoms.
Is a group of atoms held tightly?
It depends on different types of matter !!!!!!
How friction can be used to transfer electrons?
When two materials rub together, the loosely held electrons of one material move to the material with the more tightly held electrons.
