Positive nuclei moving about in a sea of electrons?
This describes the structure of metallic elements like iron or aluminum. The positive nuclei are surrounded by a "sea" of delocalized electrons, allowing for good electrical conductivity due to the free movement of electrons. This structure accounts for the unique properties of metals such as malleability and ductility.
What is the kernel of an atom?
The nucleus of an atom is its core where the protons and neutrons are located. The nucleus makes up the majority of the atom's mass and contains nearly all of its positive charge. Electrons orbit around the nucleus in specific energy levels.
What are the mobile electrons surrounding the positive ions called in a metallic bond?
The mobile electrons surrounding the positive ions in a metallic bond are called "delocalized electrons." These electrons are free to move throughout the structure of the metal, giving it its characteristic properties such as high electrical conductivity and malleability.
Why and how do metallic compounds conduct electricity?
Metallic compounds conduct electricity because they have delocalized electrons that are free to move throughout the structure. When a voltage is applied, these electrons can flow easily and carry the electric current. This is due to the metallic bonding in which metal atoms share their electrons in a "sea of electrons."
Which type of bond forms a structure which is often described as an electron sea?
Metallic crystal consists of an assemblage of positive ions immersed in a sea of mobile electrons. Thus, each electron belongs to a number of positive ions and each positive ion belong to a number of electrons. The force that binds a metal ion to a number of electrons within its sphere of influence is known as metallic bond. This force of attraction is strong and is thus responsible for a compact solid structure of metals
Describe the plum-pudding model of the atom?
A Description of electrons scattered inside the atom
How did J. J. Thomson change the atomic model based on his experimental results?
He described the atom as a sea of positive charge sprinkled with electrons
When does electricity flow inside solid electrical conductors?
when the 'sea of electrons' within the material are free to move from one area of the conductor to another. This is caused by a charge being placed on either end of the conductor, which will attract the negative electrons to the positive charge, and repell them from the negative charge, hence creating a flow.
How did the results of JJ Thomson's experiments change how scientists thought about atoms?
He described the atom as a sea of positive charge sprinkled with electrons
If you took away one electron from iron what would the charge of the ion formed be?
If you assume that the iron is in equilibirum and there are initially as many protons as there are electrons, then the total charge is zero (because the protons and electrons cancel out). Now if you remove one electron (which has negative charge), you leave a net positive charge on the iron because there are more protons than there are electrons. In reality, I think electrons from other nearby iron atoms would fill the void because this "free sea of electrons" is a property of metals.
Does metallic bonding involve free-floating electrons?
Yes, metallic bonding involves free-floating electrons that are delocalized and are able to move freely throughout the metal structure. These mobile electrons are responsible for many properties of metals, such as electrical conductivity and malleability.
Does nitrogen have a positive or negative charge?
both. no plant can live without it, having to use photosynthesis to get food. there are also downsides, the polar ice caps are melting which is causing the sea level to rise therefore changing the weather Also it has no charge it's a compound not an ion.

What is the sea of electrons model?
The sea of electrons model is a concept in chemistry that describes the behavior of electrons in metallic bonds. In this model, metal atoms are considered as positive nuclei surrounded by a "sea" of mobile delocalized electrons. These electrons are free to move throughout the metal lattice, giving metals their characteristic properties such as high electrical conductivity and malleability.
Is the sea floating on the Earth or is the Earth floating on the sea?
the sea is technically floating on the earth, as at the bottom of the sea there are techtonic plates.. Our oceans are just gigantic canyons that are filled to the brim with water.
What is the reason why we cannot feel that we are floating?
I do not know about you, but when I am floating in the sea, I can definitely feel I am floating.
A metallic bond forms when positive ions attract?
delocalized electrons in a lattice structure, allowing the atoms to share electrons and create a "sea of electrons" that holds the metallic structure together.
