Practice- TCI Lesson 1 Vocab.

Front

What is the fundamental building block of all matter?

Back

element

Answer explanation

The unique particle that is the fundamental building block of all matter is called an atom. Atoms combine to form elements, but the atom itself is the basic unit of matter.

Front

What is the table called that lists all known elements and groups them by shared properties?

Back

periodic table of the elements

Answer explanation

The table that groups elements by shared properties is called the periodic table of the elements. It organizes elements based on their atomic number and similar chemical behaviors, making it a fundamental tool in chemistry.

Front

What do you call an individual particle of an element?

Back

atom

Answer explanation

An individual particle of an element is called an atom. Atoms are the basic building blocks of matter, while elements are pure substances made up of one type of atom. The other options do not refer to individual particles.

Front

What do Adeel, Aria, and Mia need to identify to ensure their solution is successful?

Back

criteria

Answer explanation

To ensure their solution is successful, Adeel, Aria, and Mia need to identify the criteria, which are the standards or requirements their project must meet. Constraints are limitations, while the periodic table and atomic mass are not relevant to their engineering project.

Front

What do you call the mass of a single atom?

Back

atomic mass

Answer explanation

The mass of a single atom is referred to as its atomic mass. This term indicates the average mass of an atom of an element, which is consistent across all atoms of that element.

Front

What is the shorthand notation of one, two, or three letters that represents the name of an element?

Back

chemical symbol

Answer explanation

The shorthand notation of one, two, or three letters that represents the name of an element is called a 'chemical symbol'. This is the correct answer, as it specifically refers to the symbols used in the periodic table.

Front

What is it called when something limits design options?

Back

constraint

Answer explanation

In design and problem-solving, a 'constraint' refers to a limitation or restriction that affects the range of possible solutions. Jaileen and Zainab's discovery of such a limitation is best described as a constraint.
