Question

instructions: answer the following questions about the reading.

1. what are atoms often compared to in the passage?

a. building foundations
b. lego bricks
c. water droplets
d. solar systems

1. which particles are found in the nucleus of an atom?

a. protons and electrons
b. electrons, protons, and neutrons
c. protons and neutrons
d. neutrons only

1. explain what atoms and molecules are, using the analogy of lego bricks. how does this analogy help you understand the relationship between atoms and molecules?
2. describe the structure of an atom, including the particles found in the nucleus and those that orbit it. what are the charges of these particles, and how do these charges contribute to the atoms stability?

Explanation:

1. Atoms are often compared to building blocks as atoms are the basic units that make up matter, similar to how building - blocks build structures.
2. Protons and neutrons are found in the nucleus of an atom. Electrons orbit the nucleus.
3. The LEGO - brick analogy helps understand that just as LEGO bricks can be combined in different ways to make various structures, atoms can combine to form different molecules.
4. The nucleus contains protons (positively charged) and neutrons (neutral). Electrons (negatively charged) orbit the nucleus. The balance of positive and negative charges helps maintain the atom's stability.

Answer:

1. A. Building foundations
2. B. Protons and neutrons
3. The analogy shows atoms combine like LEGO bricks to form molecules.
4. Nucleus has protons (+) and neutrons (neutral), electrons (-) orbit. Charge - balance contributes to stability.
