What happens to Group 1 elements as you go down the group?

What happens to Group 1 elements as you go down the group?

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 happens to the Group 1 elements as you go down the periodic table when reacting with water?

All the alkali metals react vigorously with cold water. In each reaction, hydrogen gas is given off and the metal hydroxide is produced. The speed and violence of the reaction increases as you go down the group. This shows that the reactivity of the alkali metals increases as you go down Group 1.

What happens to elements as you go down the periodic table?

Atoms get bigger as you go down a column on the periodic table. This is because in going down a column you are jumping up to the next higher main energy level (n) and each energy level is further out from the nucleus – that is, a bigger atomic radius. Atoms get smaller as you go across a row from left to right.

Does boiling point increase down Group 1?

The figure above shows melting and boiling points of the Group 1 elements. 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.

Which element in group 1 reacts most vigorously with water?

Sodium is the alkali element that reacts most violently with water.

Which element in group 1 is the most reactive in water?

hydrogen
The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table – they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen.

Does atomic size increase left to right?

The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group.

What increases in periodic table?

Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity.

Why do boiling points decrease in Group 1?

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.

Why does density increase down Group 1?

Generally, we see that in alkali metals the rate of increase of mass is greater than rate of increase of volume, therefore the density increases down the group.

What happens to Group 1 elements as you go down?

As you go down group 1, the atomic number and Atomic Mass increase. Electronegtivity decreases and atomic radius increases. Home Science Math and Arithmetic

What happens as you move down the periodic table?

In metals , down the group reactivity increases whereas in non metals, down the group reactivity decreases. What are the Patterns on the periodic table as you move down each group?

What happens to the reactivity of Group 1 elements?

In group 1 all the elements are metals and metals react with other elements by losing their outermost electron. Group 1 elements have only one valence electron and they are highly reactive metals because they have to lose only this lone electron.

What happens to electrons as you go down a group?

the atoms get larger as you go down the group the outer electron gets further from the nucleus as you go down the group the attraction between the nucleus and outer electron gets weaker as you go down the group – so the electron is more easily lost 1
