The Table and Elements

This is the icon that is on the solid elements.

These are extremely stable by themselves.

These determine the chemical properties of an element.

This is another word for luster.

This is a good word to describe non-metals.

Some radioactive isotopes decay by changing their neutrons into different particles.

This is the number of neutrons plus the number of protons.

What is the symbol for the element Carbon?

Elements in these often have similar chemical and physical properties.

This happens when an unstable atomic nucleus changes into another nucleus.

A scientist who develops an element gets to name it!

This is the number of groups in the current periodic table of elements.

These are the horizontal (left to right) rows of elements.

Scientists have made elements with high atomic numbers using this.

This is the number of the group where are halogens are found.

There are this many regions on the table of elements.

This is the ability of a material to transfer electricity or thermal (heat) energy.

This is time it takes for a radioactive isotope to decay to half its original mass.

This determines the kind of bond that is formed.

Isotopes are isotopes because the number of these is different.

These are also known as metalloids.

The process of naming elements is fairly simple.

If an atom is made by humans it is called this.

There is more than one type of table of elements.

The most reactive metals are found in these groups.

The is a vertical (up and down) column on the table of elements.

This person won the Nobel Prize in Chemistry in 1911 for the discovery of polonium and radium.

This region has the most elements.
