What is a limitation of the Bohr Model?

Back

The Bohr Model did not explain the movement of electrons or the interaction between the subatomic particles.

Front

What did Rutherford's atomic model fail to explain?

Back

Rutherford's model failed to explain why the negatively charged electrons were not pulled into the positively charged nucleus.

Front

What is an isotope?

Back

An isotope is two or more forms of the same element that have the same number of protons but different numbers of neutrons.

Front

What is the Plum Pudding Model?

Back

The Plum Pudding Model, developed by JJ Thomson, describes an atom as a positively charged sphere with electrons embedded within it.

Front

What is the atomic number?

Back

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

Front

What is the mass number?

Back

The mass number is the total number of protons and neutrons in an atom's nucleus.

Front

What is the difference between protons and neutrons?

Back

Protons are positively charged particles found in the nucleus, while neutrons are neutral particles that also reside in the nucleus.

Front

What is the charge of an electron?

Back

Electrons have a negative charge.

Front

What is the significance of the nucleus in an atom?

Back

The nucleus contains protons and neutrons and is the center of an atom, holding most of its mass.

Front

What is the role of electrons in chemical bonding?

Back

Electrons, particularly valence electrons, are involved in forming chemical bonds between atoms.
