Atomic Structure and Particles

Front

What is the atomic structure?

Back

The atomic structure refers to the arrangement of protons, neutrons, and electrons in an atom. Protons and neutrons are located in the nucleus, while electrons orbit around the nucleus.

What is an electron?

Back

An electron is a negatively charged subatomic particle that orbits the nucleus of an atom. It has a very small mass compared to protons and neutrons.

Front

What is a proton?

Back

A proton is a positively charged subatomic particle found in the nucleus of an atom. The number of protons determines the atomic number and identity of the element.

Front

What is a neutron?

Back

A neutron is a neutral subatomic particle found in the nucleus of an atom. Neutrons contribute to the mass of the atom but do not affect its charge.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons when forming chemical bonds.

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of elements organized by increasing atomic number, which reflects the number of protons in the nucleus.

Front

What is the significance of the atomic number?

Back

The atomic number indicates the number of protons in an atom and determines the element's identity.

Front

What is VSEPR theory?

Back

VSEPR (Valence Shell Electron Pair Repulsion) theory is used to predict the shape of molecules based on the repulsion between electron pairs in the valence shell.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is an ionic bond?

Back

An ionic bond is a chemical bond formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.
