The Basics of Atoms and Ions

What are the two parts of an atom?

a. the nucleus and the proton cloud
b. the neutron and the electron cloud
c. the neutron and the proton cloud
d. the nucleus and the electron cloud

When an atom that has no charge loses two electrons, it becomes a

a. positive ion
b. negative ion
c. positive isotope
d. negative isotope

Answer:

The two main components of an atom are the nucleus and the cloud of electrons.

Explanation:

When an atom that has no charge loses two electrons, it becomes a positive ion.

Atoms are made up of two main parts: the nucleus, which contains protons and neutrons, and the electron cloud surrounding the nucleus. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.

When an atom loses two electrons, it becomes a positive ion because it now has more protons than electrons, resulting in an overall positive charge.

Understanding the basic structure of atoms and how ions are formed is fundamental in the study of chemistry and physics. It allows scientists to predict the behavior of elements and molecules in various chemical reactions and physical processes.
