What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It is a key concept in understanding chemical bonding and reactivity.

Which element has the highest electronegativity in the halogens?

Back

Fluorine (F) has the highest electronegativity among the halogens.

Front

What defines an element?

Back

An element is defined by its number of protons, which is unique to each element.

What are the properties of metals?

Back

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

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configurations, and recurring chemical properties.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is a mole in chemistry?

Back

A mole is a unit of measurement in chemistry that represents 6.022 x 10²³ particles (atoms, molecules, ions, etc.).

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.
