Atomic Structure in Detail

What is an Atom?

An atom is the smallest unit of an element that retains its chemical properties.

Subatomic Particles

Atoms consist of:

• Protons (positive charge)

• Neutrons (no charge)

• Electrons (negative charge)

Electron Arrangement

Electrons are arranged in energy levels or shells.

Understanding electron arrangement helps explain chemical behavior.

Periodic Table and Its Importance

Organization of Elements

The periodic table arranges elements based on:

• Atomic number

• Chemical properties

Periods and Groups

• Periods are horizontal rows

• Groups are vertical columns

Periodic Trends

Students learn trends such as:

• Atomic size

• Electronegativity

• Reactivity

Chemical Bonding Explained

Why Do Atoms Form Bonds?

Atoms form bonds to become stable.

Ionic Bonding

Occurs when electrons are transferred between atoms.

Example:

• Sodium and chlorine forming sodium chloride

Covalent Bonding

Occurs when electrons are shared between atoms.

Example:

• Water molecule

Chemical Reactions in Detail

What is a Chemical Reaction?

A chemical reaction is a process where substances change into new substances.

Types of Reactions

Combination Reaction

Two or more substances combine to form one product.

Decomposition Reaction

One substance breaks into simpler substances.

Displacement Reaction

One element replaces another in a compound.

Neutralization Reaction

Acid reacts with base to form salt and water.

Balancing Equations

Balancing ensures:

• Law of conservation of mass is followed

• Equal number of atoms on both sides

Acids, Bases, and Salts

Properties of Acids

• Sour taste

• React with metals

• Turn blue litmus red

Properties of Bases

• Bitter taste

• Soapy texture

• Turn red litmus blue

Neutralization

Acid + Base → Salt + Water

This reaction is widely used in daily life.

Importance of Practical Chemistry

Chemistry is a practical subject that requires experiments.

Laboratory Work

Students learn through:

• Experiments

• Observations

• Chemical reactions

Safety in Labs

Students must follow safety rules such as:

• Wearing protective gear

• Handling chemicals carefully
