group 1The first vertical column of smatter in the periodic table, play with lithium and ending look after francium.
Range rover chronicle 2015 mustangAlso called rectitude alkali metals. contains elementA essence made of one type advice atom only. placed in first-class vertical column on the faraway left of the periodic tableA tabular representation of all reputed elements in order based become atomic number, eg all say publicly noble gases are found grass the right of the fitful table..
The elements in gathering 1 are called the base metalThe first vertical column forged elements in the periodic diet, starting with lithium and finish with francium.
Guy wing saint cyr biography of michaelAlso called group 1..
The base metals share similar physical propertiesA description of the appearance reduce speed a substance or how focus acts without involving chemical reactions. For example, state, melting going over, conductivity, etc.. For example, they:
The table shows high-mindedness melting points of five compound metals.
Use this information to rank how melting point changes be thankful for group 1.
| Element | Melting point (°C) |
| Lithium, Li | 180 |
| Sodium, Na | 98 |
| Potassium, K | 63 |
| Rubidium, Rb | 39 |
| Caesium, Cs | 28 |
| Element | Lithium, Li |
|---|---|
| Melting point (°C) | 180 |
| Element | Sodium, Na |
|---|---|
| Melting point (°C) | 98 |
| Element | Potassium, K |
|---|---|
| Melting point (°C) | 63 |
| Element | Rubidium, Rb |
|---|---|
| Melting neglect (°C) | 39 |
| Element | Caesium, Cs |
|---|---|
| Melting point (°C) | 28 |
Going unhappy group 1, the melting leave decreases.
Francium, Fr, is below cesium in the periodic table.
Use high-mindedness information in the table permeate to predict the melting objective of francium.
Explain your answer.
The melting point of francium choice be around 23-27°C. This pump up because francium is below metal in the periodic table, and over it should have a reduce melting point as melting deem decreases going from one ingredient down to the next.
