Electronegativity
Linus Pauling defined electronegativity as "the ability of an atom in a molecule to attract electrons to itself."
The term which means the amount that a given atom (or radical) attracts electrons is electronegativity.
Electronegativity is the term used to describe the degree to which an atom in a molecule attracts electrons in a chemical bond. It helps determine the distribution of charges in a molecule and influences the overall polarity of the compound.
Electronegativity, symbol χ (the Greek letter chi), is a chemical property that describes the tendency of an atom or a functional group to attract electrons (or electron density) towards itself and thus the tendency to form negative ions.[1] An atom's electronegativity is affected by both its atomic number and the distance that its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it.Taken from Wikipedia entry titled Electronegativity.
In atomic physics, orbit refers to the path that electrons take around the nucleus of an atom. Electrons have a negative charge, while the nucleus, which contains protons, has a positive charge. The positive charge of the protons in the nucleus attracts the negatively charged electrons, allowing them to maintain their orbits around the nucleus. Thus, the term "orbit" itself does not have a charge but describes the behavior of charged particles in an atom.
An isotope.
The term is 'Valency'
Yes, compounds have valence electrons. Valence electrons are the outermost electrons of an atom involved in chemical bonding, and they are also involved in forming compounds by interacting with other atoms' valence electrons.
The term that describes an atom or molecule with an equal number of protons and electrons, making it electrically neutral in chemistry, is "neutral."
electronegativity. It describes how strongly an atom attracts electrons in a chemical bond, denoting its tendency to gain electrons and form negative ions. Electronegativity values are used to predict the type of bond (ionic, polar covalent, or nonpolar covalent) that will form between atoms.
The term for an atom whose electrons have the lowest possible energies is "ground state." In this state, electrons are in their lowest energy levels or orbitals, closest to the nucleus. Excited states refer to when electrons are in higher energy levels, further away from the nucleus.
The term isotope is used to indicate the different varieties of a single element, based upon variations in the number of neutrons in the nucleus. Every atom can be described as an isotope if we specify the number of neutrons. And every atom can lose electrons (a process officially called ionization). There is no relation between the number of neutrons and the loss of electrons.
