Flashcard on Atomic Structure

Front

What is the periodic table?

Back

A tabular arrangement of chemical elements, organized by increasing atomic number, where elements with similar properties are grouped together.

Front

What is a family in the periodic table?

Back

A group of elements in the same column of the periodic table that share similar chemical properties.

Front

What is a compound?

Back

A substance formed when two or more elements are chemically bonded together.

Front

What is the formula for water?

Back

H2O, which means it is composed of 2 atoms of hydrogen and 1 atom of oxygen.

Front

What is passive transport?

Back

The movement of substances across a cell membrane without the use of energy, typically from an area of higher concentration to an area of lower concentration.

Front

How do particles behave in a solid?

Back

Particles in a solid vibrate in place and are closely packed together.

Front

How do particles behave in a liquid?

Back

Particles in a liquid slide past one another and are less tightly packed than in a solid.

Front

What happens to cells in a hypertonic solution?

Back

Cells will lose water and shrink because the concentration of solutes outside the cell is higher than inside.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the difference between an element and a compound?

Back

An element is a pure substance that cannot be broken down into simpler substances, while a compound is made up of two or more elements chemically combined.
