When an atom gains or loses electrons What is the charged particle?
form when an atom or group of atoms gains or loses one or more electrons. When an atom gains electrons, it becomes a negatively charged ion, called an anion. When an atom loses electrons, it becomes a positively charged ion called a cation.
When an atom gains or loses electrons the charged particle that results is called a molecule True or false?
Science
| Question | Answer |
|---|---|
| Particles formed from the covalent bonding of atoms are called IONS. | False, molecules |
| Molecules are NEUTRAL | Truth |
| When an atom gains or loses electrons, the charged particles that results is called a MOLECULE | False, ion |
What are particles formed from the covalent bonding of atoms called?
Ions
Explanation: Ions results from the transfer of electrons between atoms.
When a group of atoms and act as a the result is known as a?
When atoms join together, the group is called a molecule. The atoms in a molecule can the the same.
What is it called when an atom loses electrons?
Explanation: When an atom gains/loses an electron, the atom becomes charged, and is called an ion. Gaining an electron results in a negative charge, so the atom is an anion. Losing an electron results in a positive charge, so atom ion is a cation.
What happens when an atom gains electrons?
If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). Energy may be lost or gained in the formation of an ion.
What happens to an atom when it loses electrons?
An atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion (see page 10 for more on ions).
What is the charge of the electron?
Electron charge, (symbol e), fundamental physical constant expressing the naturally occurring unit of electric charge, equal to 1.602176634 × 10−19 coulomb.
Which element has the strongest attraction for electrons?
Fluorine
Explanation: Fluorine has the greatest attraction for electrons in any bond that it forms. The attraction of an atom for shared electrons is called its electronegativity.
What is it called when atoms join together?
A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound. All compounds are molecules, but not all molecules are compounds. When two hydrogen atoms combine with one oxygen atom, it becomes the compound water.
