What Electrons that are free to move in a metal are referred to as?
Electrons that are free to move in a metal are referred to as "conduction electrons." These electrons are not bound to any specific atom and can move freely throughout the metal lattice, allowing for the conduction of electricity. This property is essential for metals to conduct electric current efficiently.
What are the three constituents of an atom and also state the nature of charge on each?
Protons- positive Nuetrons-nuetral electons-negative
How many protons and electrons does a neutron have?
None. Protons and electrons are not constituents of a neutron. Both neutrons and protons are constituents of an atom's nucleus (core), while the electrons are situated in the electronic cloud around the nucleus.
What has a negative charge and can move from atom to atom?
electrons
What happens when an atom of metal an atom of nonmetal are combined?
The metal loses its electrons and trannsfers them to the non-metal to form an ioinic bond.
The lightest of an atom's main constituents?
An atom is composed of three main particles, the proton, electron and neutron. The electron is the lightest among the three.
Electrons can move from atom to atom.?
elecron can move from atom to atom... yes
What are the constituents of bell metal?
Bell metal is a type of bronze consisting of 78% copper and 22% tin.
What are the three constituents of an atom and also state the nature of charge on each?
Protons- positive Nuetrons-nuetral electons-negative
Why do we say that in metal conductors, electrons move but protons don't?
In metal conductors, electrons move because they are negatively charged particles that can flow freely. Protons, on the other hand, are positively charged particles that are tightly bound within the nucleus of an atom and do not move easily in a conductor.
When a metal atom combines with a non-metal atom how will the non-metal atom react?
metal and non metal usually combines to form complexes. as the valecy to be satisfied by both does not let them to form simple compounds with each other
What are the electrons when metal atom and non metal atom react?
When a metal reacts with a non-metal, the electrons move from the metal to the non-metal. This is because the metal can achieve valence when it loses the electrons in its outer shell. The non-metal can also achieve full valence by gaining the electron in its outer shell.
Is zinc an atom?
Yes. Zn is a metal atom.
How does heating acid make metal dissovle faster?
Heating a substance causes the molecules within it to move more quickly. So imagine that every surface atom of the metal reacted with acid: the faster the reacted material can move away from the unreacted metal, the faster new acid molecules can get close enough to the metal to react.
When do ionic bonds form?
They are formed when a strong metal atom is bonded with a strong non metal atom.
Why are metals good heat conductors?
Some of the outer electrons of metal atoms are free to move from atom to atom. These free electrons transfer heat readily making metals good thermal conductors.
How Metallic bonding causes medals to conduct electric current?
Metals conduct electricity and electric current. Electric current is possible when charged particles are free to move. A metallic bond is the bond between a positive metal and the atoms in metal (metal atoms combined in regular patterns in which valence electrons are free to move from atom to atom). ~let me guess page 180 problem 16 haha physical science :)
