Flashcard Set on Periodic Table and Chemical Elements

Front

What is the periodic table?

Back

The periodic table is a way to organize all known chemical elements, showing their properties and relationships.

Front

What is an element?

Back

An element is a pure substance that cannot be broken down into simpler substances and has a unique chemical symbol.

Front

What is a chemical symbol?

Back

A chemical symbol is one or two letters that represent an element, such as 'H' for hydrogen and 'O' for oxygen.

Front

What is the atomic number?

Back

The atomic number is the number of protons in an atom and serves to uniquely identify an element.

What are metals?

Back

Metals are solid elements at room temperature, except for mercury, and they conduct heat and electricity well.

Front

What are non-metals?

Back

Non-metals can be solids, liquids, or gases and do not conduct heat and electricity well.

Front

What are groups in the periodic table?

Back

Groups are columns in the periodic table that contain elements with similar chemical properties.

Front

What are chemical reactions?

Back

Chemical reactions are processes in which elements combine or separate to form new substances.

Front

What are protons?

Back

Protons are positive particles found in the nucleus of an atom and determine the atomic number.

Front

What are electrons?

Back

Electrons are negative particles that orbit around the nucleus of an atom and influence chemical reactions.
