Bohr Models

Front

What is the mass number of an atom?

Back

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

Front

What is the atomic number of an atom?

Back

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

Front

What element is represented by the Bohr model with 12 protons?

Back

The element is Magnesium.

Front

What is the mass number of Chlorine if it has 17 protons and 18 neutrons?

Back

The mass number of Chlorine is 35.

Front

What are isotopes?

Back

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons.

Front

How do you calculate the mass number of an atom?

Back

The mass number is calculated by adding the number of protons and neutrons in the atom.

Front

What is the significance of the atomic number in the periodic table?

Back

The atomic number determines the position of an element in the periodic table and its chemical properties.

Front

What is the relationship between mass number and isotopes?

Back

Isotopes of an element have the same atomic number but different mass numbers due to varying numbers of neutrons.

Front

How many electrons does a neutral atom of Magnesium have?

Back

A neutral atom of Magnesium has 12 electrons, equal to its atomic number.

Front

What is the maximum number of electrons that can occupy the first energy level in a Bohr model?

Back

The maximum number of electrons that can occupy the first energy level is 2.
