The electron sea model represents the way electrons exist in metals.
Electrons in metals can move freely within the material due to the delocalized electron cloud formed by the overlapping atomic orbitals. This allows for high electrical conductivity in metals as the free electrons can carry electric current.
metallic bond
A metal's luster is not directly due to its valence electrons. Instead, it is a result of the way metals allow light to reflect off their free-flowing electrons in a phenomenon called metallic bonding, which gives metals their shiny appearance. Valence electrons play a role in the electrical and thermal conductivity of metals, rather than their luster.
Metals have good conductivity because of the way their atoms are arranged. Metals have a "sea of delocalized electrons" that are free to move through the lattice of metal ions, allowing for easy flow of electric current. This mobility of electrons is key to good conductivity in metals.
No, different metals react differently based on their unique properties. Some metals react readily with certain substances, while others are more resistant to reactions. Factors such as reactivity, stability, and valence electrons all contribute to how metals react.
In metallic bonding, valence electrons are delocalized and free to move among the atoms. This creates a "sea of electrons" that holds the metal atoms together in a lattice structure. The sharing of electrons in this way gives metals their characteristic properties, such as conductivity and malleability.
Metals are good conductors of thermal energy because they have free electrons that can move easily between atoms, carrying heat energy quickly throughout the material. This mobility of electrons allows metals to efficiently transfer thermal energy from one place to another.
You are perhaps thinking of the metallic bond. You could also describe electons in metals as a cloud.

Metals behave in a rather unique way as far as their electrons are concerned.The electrons in metals are de-localised, which in effect means they are not bound to a particular atom, like a "sea of electrons".This property makes them good conductors of electricity because charged electrons can easily travel from one end of the metal to the other whilst maintaining that charge.
Group number corresponds to the number of valence electrons of a single atom of the element.
When they fill their outermost energy levels. Metals will WANT more electrons and Non-Metals will have EXTRA electrons to give. So in a way, Metals will actually fill their outermost energy levels while Non-Metals will empty them; all with the goal of having a FULL valency shell which is stable. This is the basis for ionic bonding.
If you mean valence electrons, then valence electrons are the number of electrons an atom has in its outer level. If you look on a periodic table, the fastest way to do this is to look at what column they are in. If it is in column one, it has one valence electron. Just don't use this rule for metals (rows 3-12) because the rule does not apply to metals. Hope this helped!
They tend to gain electrons when reacting with a metal. Metals generally are short of a full octet by 1 to 4 valence electrons. It is easier to drop 2 electrons than try to gain 6 electrons. The elements in group four can go either way, but the other metals will give up electrons, and non-metals will take them.
non metals generally have more valence electrons and non metal have less
Metals tend to form cations because they have low electronegativity and tend to lose electrons easily to achieve a stable electron configuration with a full outer shell. This results in the formation of positively charged ions (cations) by losing one or more electrons.
The group number tells you how many valence electrons there are, except for transition metals, lanthanides, and actinides. So, for groups 1 and 2 , there are 1 and 2 valence electrons, respectively. Then it gets a little tricky. You skip to group 13, past the transition metals. What to do? You can't have 13 valence electrons. What you do is you use only the ones digit. Thus, metals in group 13 would have 3 valence electrons. The reason that the group number tells you the number of electrons is that that is the way that Dmitri Mendeleev ( the founder of the periodic table) set it up. Good Luck!
Yes it does in what is called an ionic reaction, where the silver gives of electrons to oxygen, the result beeing silver oxide (Ag2O). All metals react with non-metals in this way. NaCl is probebly the most famouse of these ionic reactions as the result is normal table salt, but it is in no sense unique. Also some metals will react more readely with the non-metals.

No actual 'lines' exist, but it is a useful way of describing a magnetic field, as it represents the direction the north pole of a magnet would move if it was free to do so.
