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.
What are positive and negative ions called?
Positive ions are called cations, and negative ions are called anions. Cations have a net positive charge because they have lost electrons, while anions have a net negative charge because they have gained electrons.
What is the Layer of electrons outside the nucleus?
the layer of electrons surrounding the nucleus of an atom is called "shells"
Why is the atom called electrically neutral?
its is neutral cuz every atom has negative electrons surrounding the nucleus which has a positive protons, each atom have the same number of protons and electrons so the cancel out each other, it becomes neutral, but there are things called positive ions and negative ions, they are atoms that looses or gains electron without the change of the protons
What are the electrons in the outmost shell of an atom called?
the electrons in the outermost shell of an atom are considered to be the valence electrons.
What are elements lose electrons and form positive ions named?
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
An atom with a positive net charge is called?
Protons of an atom carry a positive charge. Electrons carry a negative charge. Neutrons carry no charge at all, but they are part of the atom.
Is most atoms have more electrons than proton?
Yes, most atoms do have more electrons than protons. This is because atoms are electrically neutral, and the number of protons (positive charge) in the nucleus is balanced by the number of electrons (negative charge) surrounding the nucleus.
What are the spheres surrounding the nucleus that contains an atom's electrons?
The spheres surrounding the nucleus of an atom are called protons and neutrons, protons hold the electrons in orbit around the nucleus because a proton has a positive charge which attracts the electron which has a negative charge causing electromagnetic force which holds the electron in orbit. The neutron determines the isotope of the atom but has a neutral charge.
Are atoms have lost electrons is called?
Atoms that have lost electrons are positive ions, and are called cations.
What are metals called after they lose electrons?
They become cations, positive ions.
An atom that has fewer protons than electrons is called what?
Generally an atom has equal number of electrons and protons. and we know that electrons are negatively charged and protons are positively charged so atom is neutral. But when an atom loses electrons it acquires a positive charge. And this positive species is called cation.
