What is the trend of melting point for Group 1?
Generally the melting point of the alkali metals decreases down the group. This is because as the ions get larger the distance between the bonding electrons and the positive nucleus gets larger and reduces the overall attraction between the two. For similar reasons the electronegativity decreases.
What is the trend shown in the boiling point of Group 1 elements?
Explanation: ☑️ In Group 1 Both the melting and boiling points decrease down the group.
What is the trend of melting and boiling point in periodic table?
Different groups exhibit different trends in boiling and melting points. For Groups 1 and 2, the boiling and melting points decrease as you move down the group. For the transition metals, boiling and melting points mostly increase as you move down the group, but they decrease for the zinc family.
What is the trend in the group 1 elements?
Explaining the trend The reactivity of group 1 elements increases as you go down the group because: the atoms become larger. the outer electron becomes further from the nucleus. the force of attraction between the nucleus and the outer electron decreases.
What is the correct trend going down groups 1 and 17?

What is the trend for melting point on the periodic table?
The melting and boiling points of the Group 1 elements decrease on descending the group. This is due to a decrease in the forces of attraction between the atoms. On crossing a period in the Periodic Table the atomic size decreases. On descending a group the atomic size increases.
What is the periodic trend for melting point?
Melting point trends on the periodic table can be understood in a crude way using the following rule of thumb: The stronger the forces that act between molecules of a substance, the higher the melting point tends to be.
What is the trend shown in the boiling point?
Boiling points increase as the number of carbons is increased. Branching decreases boiling point.
What is the trend in melting points?
The general trend is that melting point increases then decreases to the right. The melting point of metals increase to the right because there are more delocalised electrons and charge of cations increase. So the cation-free electron attraction increases and the metallic bond gets stronger.
What is the trend for boiling point?
As the size decreases the strength of van der Waals forces also decreases. As strength decreases, the boiling point also decreases. There decreases in boiling point is observed as we move from left to right of the periodic table with some exceptions.
Does melting point decrease down group1?
Both the melting and boiling points decrease down the group. When any of the Group 1 metals is melted, the metallic bond is weakened enough for the atoms to move more freely, and is broken completely when the boiling point is reached.
Why melting and boiling point decreases down the group?
The decrease in melting and boiling points reflects the decrease in the strength of each metallic bond. When any of the Group 1 metals is melted, the metallic bond is weakened enough for the atoms to move more freely, and is broken completely when the boiling point is reached.
What is the trend in melting and boiling points of elements?
This trend is quite evident from the data given in the table below. In alkali metals and alkaline earth metals, the melting and boiling points of elements decrease with increase in atomic number. The mixed trends are observed in Boron Family elements, Carbon Family elements, Nitrogen Family elements and Oxygen Family elements.
What happens to Group 1 metals when they are melted?
When any of the Group 1 metals is melted, the metallic bond is weakened enough for the atoms to move more freely, and is broken completely when the boiling point is reached. The decrease in melting and boiling points reflects the decrease in the strength of each metallic bond. 25 insanely cool gadgets selling out quickly in 2021.
Why does the melting point of alkali metals decrease down the group?
There is more shielding between the nucleus and the outer electrons and the distance between the nucleus and the outer electron increases and therefore the force of attraction between the nucleus and outer most electrons is reduced. Generally the melting point of the alkali metals decreases down the group.
What are the trends in Group 1 on the periodic table?
The Periodic Table. Trends in Group 1. Title. Trends in Group 1. Note: Even though Hydrogen will appear above Lithium on the periodic table it is not considered a part of Group 1. Group 1 elements are known as Alkali Metals. They are called s-block elements because their highest energy electrons appear in the s subshell.
