Textbook Question

Electrons .a. are negatively charged;b. along with neutrons make up the nucleus;c. are attracted to the negatively charged nucleus;d. are not involved in ionic bonds;e. all of the above are true

Verified step by step guidance

Step 1: Understand the basic properties of electrons. Electrons are subatomic particles with a negative charge.

Step 2: Analyze option (a). Electrons are indeed negatively charged, which is a fundamental property of electrons.

Step 3: Evaluate option (b). The nucleus of an atom is composed of protons and neutrons, not electrons. Electrons orbit the nucleus.

Step 4: Consider option (c). The nucleus is positively charged due to protons, so electrons are attracted to it, not repelled.

Step 5: Examine option (d). Electrons are involved in ionic bonds, as they are transferred between atoms to form ions.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Charge of Electrons

Electrons are subatomic particles that carry a negative electric charge. This charge is fundamental to their behavior in atoms and influences how they interact with other charged particles, such as protons, which are positively charged.

Structure of the Atom

An atom consists of a nucleus made up of protons and neutrons, with electrons orbiting around it. Neutrons are neutral and do not affect the charge, while protons contribute to the positive charge of the nucleus, creating an attractive force that holds electrons in their orbits.

Ionic Bonds

Ionic bonds are formed when electrons are transferred from one atom to another, resulting in the formation of charged ions. Electrons play a crucial role in this process, as they are the particles that are lost or gained, leading to the attraction between oppositely charged ions.
