Atomic structure, periodic trends, and bonding

Front

What is the atomic structure of an atom?

Back

An atom consists of a nucleus containing protons and neutrons, surrounded by electrons in orbitals.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What are the three main subatomic particles?

Back

The three main subatomic particles are protons (positive charge), neutrons (no charge), and electrons (negative charge).

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 attraction between oppositely charged ions.

Front

What are metals?

Back

Metals are elements that are typically malleable, ductile, good conductors of heat and electricity, and have a shiny appearance.

Front

What is a periodic trend?

Back

Periodic trends are patterns in the properties of elements that can be observed across periods and groups in the periodic table.

Front

What is malleability?

Back

Malleability is the ability of a material to be deformed or shaped under compressive stress, often by hammering or rolling.

Front

What is conductivity?

Back

Conductivity is the ability of a material to conduct electric current or heat.

Front

What is the significance of Chadwick's discovery?

Back

Chadwick discovered the neutron, which explained the existence of isotopes and contributed to the understanding of atomic structure.
