SOL Review PS.4 Level 2

Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electrical charge.

Front

What does it mean for an element to form a +1 ion?

Back

It means the element has lost one electron, resulting in a positive charge.

Front

Which group in the periodic table contains elements that typically form +1 ions?

Back

Group 1, also known as the alkali metals, typically form +1 ions.

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Which element has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity of all elements.

Front

What is the significance of melting points in elements?

Back

Melting points indicate the temperature at which a solid becomes a liquid, reflecting the strength of the forces holding the atoms together.

Front

Which type of elements generally have high melting points?

Back

Metals, especially transition metals like Iron (Fe), generally have high melting points.

Front

What is the state of matter for Mercury (Hg) at room temperature?

Back

Mercury (Hg) is a liquid at room temperature.

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.

Front

What group does an element with 15 protons belong to?

Back

An element with 15 protons belongs to Group 15 of the periodic table.
