Physical properties
Energy is the ability to cause a change in matter.
The appearance of lawrencium is not known.
If the substance is an element the answer is an atom. If the substance is a compound the answer is a molecule.

Nobody knows
Not much is known yet about the properties of dark matter, so it is really hard to compare this.
Not known, probably a metallic appearance.

The branch of physical science studies the properties of matter and changes in matter is known as chemistry. This is a branch which is mainly concerned with atoms and molecules and how they interact.

Cleopatra was known for her politics. None of the ancient writers describe her as beautiful, but they do not say that she was ugly. They say that her physical appearance was average.
We don't really know very much about dark matter, so most of its properties (like how it feels) are not known.
Database properties are also known as database attributes or characteristics. These properties describe the features and characteristics of the database, such as data types, constraints, relationships, and indexing among others. They are essential for defining the structure and behavior of a database system.
Mainly that dark matter interacts with dark matter and with normal matter via the gravitational force; and that it DOES NOT interact with normal matter via any other known force. Or, if there is any interaction, it does so to such a small extent that it hasn't been possible to detect this so far.
