N5 Atoms and Bonding

Front

How are elements in the Periodic Table arranged?

Back

In order of increasing atomic number.

Front

Why do elements within a group have similar chemical properties?

Back

Because they have the same number of electrons in their outer energy levels.

Front

What is the charge of protons, neutrons, and electrons?

Back

Protons: one-positive, Neutrons: neutral, Electrons: one-negative.

Front

What does the atomic number represent?

Back

The number of protons in an atom.

Front

What is the relationship between protons and electrons in a neutral atom?

Back

The number of electrons is equal to the number of protons.

Front

What is the mass number of an atom?

Back

The number of protons added to the number of neutrons.

Front

What are isotopes?

Back

Atoms with the same atomic number but different mass numbers, or atoms with the same number of protons but different numbers of neutrons.

Front

What are relative atomic masses?

Back

The average atomic mass calculated for each element using the mass and proportion of each isotope present.

Front

How do covalent bonds form?

Back

Between non-metal atoms when two positive nuclei are held together by their common attraction for a shared pair of electrons.

Front

What are the 7 elements that are diatomic molecules?

Back

H₂, N₂, O₂, F₂, Cl₂, Br₂, I₂.
