How ions knock off electrons from atoms?
When ions collide with atoms, they transfer energy through collisions with the outer electrons of the atom. This transfer of energy can disrupt the balance of the electrons in the atom, causing an electron to be knocked off or ejected. This process is known as ionization and can result in the creation of new ions.
What are particles that make up a compound called?
The particles that make up a compound are called molecules or ions. Molecules are formed when two or more atoms chemically bond together, while ions are formed when atoms gain or lose electrons to achieve a stable electronic configuration.
How are electrons removed from atoms to form ions in a mass spectrometer?
The vaporised sample passes into the ionisation chamber. The electrically heated metal coil gives off electrons which are attracted to the electron trap which is a positively charged plate. The particles in the sample (atoms or molecules) are therefore bombarded with a stream of electrons, and some of the collisions are energetic enough to knock one or more electrons out of the sample particles to make positive ions. Most of the positive ions formed will carry a charge of +1 because it is much more difficult to remove further electrons from an already positive ion. These positive ions are persuaded out into the rest of the machine by the ion repeller which is another metal plate carrying a slight positive charge.
Why do atoms like carbon and nitrogen not like to make ions about sodium and chlorine do?
Atoms like carbon and nitrogen do not readily form ions because they have stable electron configurations in their outer shells, making them less likely to gain or lose electrons. Carbon and nitrogen tend to share electrons in covalent bonds rather than give them up or take them from other atoms. In contrast, sodium and chlorine readily form ions because they have fewer or more electrons in their outer shells, respectively, making it easier for them to achieve a stable electron configuration through ion formation.
What is the name given to the three particles that make up atoms?
The three particles that make up atoms are protons, neutrons, and electrons.

What are the two basic ways in which ions form from atoms?
Ions are formed when atoms gain or lose electrons. An atom that loses electrons becomes a positively charged ion known as a cation, while an atom that gains electrons becomes a negatively charged ion known as an anion.
Why do some atoms form positive ions and others form negative ions?
It is a matter of how full an atom's outer or valence shell of electrons is. For most atoms, the most stable setup is one with a full shell of 8 valence electrons, and an atom will gain or lose electrons to achieve this. For atoms with close to 8 valence electrons, such a chlorine (7 valence electrons, it is generally easier to gain electrons and thus become negatively charged. For atoms with few valence electrons, such as sodium (1 valence electron), it is easier to lose electrons and go down to the next lowest shell, which is already full.
How do you make an atom negative?
An atom becomes negative by gaining one or more extra electrons, which gives it a net negative charge. This can occur through chemical reactions where atoms either share or transfer electrons with other atoms. Negative ions are also known as anions.
What are particles that make up a compound called?
The particles that make up a compound are called molecules or ions. Molecules are formed when two or more atoms chemically bond together, while ions are formed when atoms gain or lose electrons to achieve a stable electronic configuration.
Atoms of metallic element tend to?
Atoms of metallic elements tend to lose electrons to form positive ions. This is because metallic elements have fewer electrons in their outermost energy level, making it energetically favorable for them to lose electrons and achieve a stable electron configuration. This leads to the characteristic properties of metals, such as conductivity and malleability.
What are the atoms that make up electricity?
Electricity is not made up of atoms; it is the flow of electrons through a conductor. Electrons are negatively charged particles found in the outer shells of atoms. When a voltage is applied, electrons move along a conductor, creating an electric current.
How atoms combine to make a bond?
Atoms combine together to form molecules. In molecules the consitutent atoms are held together by attractive forces. This attractive force which binds the atoms in a molecules is called as bond.
Why does argon not form ions?
Atoms become ions by gaining or losing electrons to achieve a noble gas configuration of electrons, which is stable. Argon already has such a configuration and is very stable as it is. Any gain or loss of electrons would make it less stable.
What happens to the valence electrons of atoms in metallic bond?
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.
Which term describes the units that make up substances formed by ionic bond?
Ions are the units that make up substances formed by ionic bonds. Ions are atoms or molecules that have gained or lost electrons, resulting in a positive or negative charge. These ions are held together by strong electrostatic forces in ionic compounds.

The vaporised sample passes into the ionisation chamber. The electrically heated metal coil gives off electrons which are attracted to the electron trap which is a positively charged plate.
