Question

word bank: proton electron cloud neutron atom elements

1. are represented by 1 or 2 letter symbols and are the simplest substances.
2. the basic particle from which an element is made is called a(n).
3. the positively charged particle of an atom is the.
4. the area where electrons orbit the nucleus is a(n).
5. a(n) is the atomic particle with no charge.

Explanation:

1. Elements are represented by symbols (e.g., H for hydrogen, O for oxygen) and are the simplest substances as they cannot be broken down further by chemical means.
2. An atom is the basic particle of an element. For example, a hydrogen atom is the basic unit of the element hydrogen.
3. A proton has a positive charge. In an atom, protons are located in the nucleus.
4. The electron cloud is the area where electrons orbit the nucleus. Electrons are negatively - charged particles.
5. A neutron has no charge. It is also located in the nucleus along with protons.

Answer:

1. Elements
2. atom
3. proton
4. electron cloud
5. neutron
