For example, there are differences in properties between the group 1 metals and the transition metals, and mercury (Hg) is a metal which is a liquid at room temperature.

Most elements in the periodic tablecloseperiodic tableA table which lists all of the chemical elements and arranges them in a way that is useful. It allows us to spot patterns and make predictions about other elements. are metals, while non-metalsclosenon-metalA substance that has the typical properties of a non-metal. Non-metal elements are on the right hand side of the periodic table. account for around 20% of known elementscloseelementA pure substance which is made from only one type of atom. Elements are listed on the periodic table..

Miss Armit: So what we're going to look at today are the metal elements in Group 1 of the periodic table, along with the metal elements in the transition metal block of the periodic table and their properties.

Likewise, if an element has most of the properties of a typical non-metal, it would be sensible to suggest that it is non-metal.

Miss Armit: Yeah, because mercury's a great conductor of heat. So, when it gets hot the space between the particles expands and then this rises up the thermometer.

An element doesn’t have to have every property of metals for you to classify it as a metal! As long as it has most metal properties, you can be confident that it is a metal.

Gethin: Today, we've got super science teacher Miss Armit with us. What she doesn't know about chemistry is not worth knowing. And today, we're going to be looking at the periodic table.

Miss Armit: It's the only liquid transistor metal and because of its properties it's perfect for a thermometer. Why do you think that is?

Looking for more resources for your chemistry lessons? In this short video, scientist Mark Miodownik visits the earliest known copper mines in Israel's Timna Valley to explain the discovery of the first metal - copper.

Miss Armit: So their key properties are they conduct electricity, they conduct heat, they are malleable - which means they're bendy - and they're shiny.

List ofmetals on the periodic table

Miss Armit: Well, we've got copper and it's a really good conductor of electricity, so we use that in our wires. We've also got iron and aluminium and they're great at conducting heat, so we use these metals for our pots and pans. And gold and silver are used in jewellery, because they're shiny, they're malleable and unreactive with oxygen, so they don't rust easily.

Transitionmetals periodic table

The periodic table can be used to find out if an element is a metal or a non-metal. Metals are found on the left and in the middle, whereas non-metals are all on the right. It is possible to use information about an element’s physical propertiesclosephysical propertyA property of an element or compound which can be directly observed or measured. For example, melting point, electrical conductivity, appearance at room temperature. to classifycloseclassifyTo arrange something into classes according to characteristics. In chemistry this is done according to physical and chemical properties. an element.

Data and observations help us to classify an element as a metal or a non-metal. We should use as many pieces of information as possible should be used to conclude.

Graphite conducts electricity, which is not typical of non-metals. However graphite is also brittle which is a typical property of non-metals.

Calcium is found on the left of the periodic table, surrounded by other metals. Calcium has the usual properties of a metal. For example it is a good conductor of heat and electricity.

We provide cutting tools for your boring process including our steel boring bars, carbide boring bars, reduced neck boring bars, threading/grooving boring bars.

So we're going to talk about transition metals, which are found in the middle of the periodic table. What are their key properties?

We often hear about calcium being in milk and dairy products, but that is when the calcium atoms are chemically bonded to other atoms to form compounds.

People use lots of metallic elements in their everyday lives. These include elements like iron, copper, gold and silver.
