Chemistry Elements and Properties Quiz

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

The region surrounding the nucleus where electrons are likely to be found.

A subatomic particle with a positive charge found in the nucleus.

A subatomic particle without a charge found in the nucleus.

A subatomic particle with a negative charge found orbiting the nucleus in the electron shell.

A table that organizes elements by their atomic number and recurring properties.

A vertical column on the periodic table. Elements in the same group share similar chemical properties.

A horizontal row on the periodic table. Elements in the same period have the same number of electron shells.

Anything that has mass and takes up space.

True. Natural gas is a substance that has mass and occupies space, making it a form of matter.

Clouds are made up of tiny water droplets or ice crystals, which have mass and occupy space. Thus, clouds are matter.

A rock is a physical object that has mass (weight) and occupies space (volume), making it matter.

A property that describes a substance's ability to change its chemical composition.

A property that can be observed or measured without changing the substance's composition.

Density is the amount of mass per unit volume.

The denser object will have more mass packed into the same volume.

Carbon is located in Group IVA, also known as Group 14, on the periodic table.

Tin is located in Period 5, the fifth row of the periodic table.

Selenium (Se) belongs to Group 6A (VIA), also known as Group 16, on the periodic table.

Thallium is a metal, Neon is a non-metal, Strontium is a metal, Tellurium is a metalloid, Sodium is a metal, Bromine is a non-metal.

The Periodic Table organizes elements into groups and periods based on their properties and electron configurations.

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

The sum of protons and neutrons in an atom's nucleus.

Atoms of the same element that have the same number of protons but different numbers of neutrons.

Electrons in the outermost shell of an atom.

A visual representation of an atom's valence electrons, where dots around the element symbol indicate the number of valence electrons.

The process of transferring electrons between atoms to form ions, creating an electrostatic attraction.

An atom with a positive or negative charge due to the gain or loss of electrons.

A force of attraction between oppositely charged ions.

A substance that cannot be broken down into simpler substances by chemical means. Each element has a unique symbol, such as 'H' for hydrogen and 'O' for oxygen.

The negatively charged subatomic particles that orbit the nucleus of an atom. They determine an atom's chemical properties.

The outer shell of an atom containing valence electrons that participate in chemical bonding.

The tendency of an atom to gain, lose, or share electrons to achieve a stable electron configuration like a noble gas. This drives chemical reactions.

A chemical bond formed by the electrostatic attraction between two oppositely charged ions, a cation (positively charged) and an anion (negatively charged).

The process in which an atom gains or loses one or more electrons to form an ion with a stable electron configuration, often resembling a noble gas.

Substances composed of non-metals that share electrons to form covalent bonds, resulting in molecules.

The chemical bond formed when two or more atoms share electrons to attain a stable electron configuration.

A representation of the bonding in a molecule showing the valence electrons as dots or lines around the atom’s symbol.

Prefixes used in naming covalent compounds to indicate the number of atoms of each element in the molecule.

A compound formed by the electrostatic attraction between a metal and a non-metal, leading to the transfer of electrons and the formation of ions.

A compound consisting of a metal cation and a polyatomic ion, which is a group of atoms with an overall charge.
