MOCK TEST FOR FINALS DAY 1 - CHEM

Front

What type of bond forms between magnesium and oxygen?

Back

Ionic bond: A type of chemical bond that occurs when electrons are transferred from one atom to another, resulting in the formation of charged ions.

Front

Which group in the periodic table is most likely to form covalent bonds?

Back

Group 14: This group contains elements that can share electrons to form covalent bonds.

Front

What is the atomic number of an element with 17 protons?

Back

17: The atomic number of an element is equal to the number of protons in its nucleus.

Front

What subatomic particle has no charge?

Back

Neutron: A subatomic particle found in the nucleus of an atom that has no electric charge.

Front

Which of the following will form an ionic bond?

Back

Sodium and chlorine: When sodium (a metal) transfers an electron to chlorine (a non-metal), they form an ionic bond.

Front

What is a covalent bond?

Back

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

Front

What is the role of protons in an atom?

Back

Protons determine the atomic number and identity of an element.

Front

What is an ion?

Back

An ion is an atom or molecule that has a net electric charge due to the loss or gain of one or more electrons.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of chemical elements, organized by their atomic number, electron configuration, and recurring chemical properties.
