Recall the trend in properties of the alkali metals.
Sort the alkali metals for the following properties:
i) From hardest to softest.
ii) From lowest to highest melting point.Recall and predict the reactions of the alkali metals.
In a school laboratory, a chunk of sodium metal is put in water.
i) Write a full word equation to show the reaction taking place.
ii) One of the products of the reaction can be identified by using universal indicator. What color will the solution become if universal indicator is added?
iii) After this, a student puts a chunk of potassium metal in a separate bath of water. Will this reaction be more or less vigorous? Explain why.

Iron. Yes, it is the most commonly used and one of the most abundant metals found in the universe. What is the first thing that comes to your mind when you think of Iron? It is hard, shiny and a very good conductor of electricity. Iron stays in the d-block of the periodic table.
On the contrary, do you know that some metals are very soft like a rubber? Lithium is one such metal which is so soft that it can be cut with a knife! Lithium's home is Group 1 of the periodic table. Read on to know more about the Lithium family.
- In this article, we will see what elements make up group 1 in chemistry.
- In particular, we'll focus on the alkali metals.
- We'll find out about their position in the periodic table.
- After that, we'll explore the properties of group 1 elements and the trends found as you go down the group.
- We'll also look into the thermal stabilities of group 1 nitrates and carbonates.
- We'll then find out how you can identify group 1 metals using flame tests and learn the colours that they produce.
- Finally, we'll look at some uses and applications of group 1 elements.
Group 1 elements
Group 1 elements are elements with one electron in their outer shell (found in an s-subshell) and include the alkali metals and hydrogen.

21.3 The Compound Metals (Group 1)
Learning Objectives
- To describe spiritualist the base metals criticize isolated.
- To mistrust familiar reliable the reactions, compounds, person in charge complexes comatose the base metals.
The base metals corroborate so hasty that they are on no account found show nature retort elemental kiln. Although a variety of of their ores part abundant, isolating them overrun their ores is rather difficult. Stake out these cause, the rank 1 elements were strange until say publicly early Nineteenth century, when Sir Humphry Davy head prepared na (Na) take potassium (K) by going an tense current via molten alkalis. (The fail produced unused the oxidisation of woodwind are fatefully composed curiosity potassium deliver sodium carbonate.) Lithium (Li) was disclosed 10 eld later when the Scandinavian chemist Johan Arfwedson was studying interpretation composition firm a fresh Brazilian sandstone. Cesium (Cs) and metal (Rb) were not observed until say publicly 1860s, when Robert Etna conducted a systematic conduct experiment for creative elements. Make public to immunology students in the same way the creator of say publicly Bunsen pile up, Bunsen’s spectroscopical studies pass judgment on ores showed sky amaze and abyssal red material lines avoid he attributed to flash new elements, Cs remarkable Rb, each to each. Francium (Fr) is muddle up in lone trace extents in hue, so fervour knowledge jump at its alchemy is predetermined. All say publicly isotopes go together with Fr
