What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
What are some fun facts about Alkali metals?
The Alkali Metals are: -lithium -sodium -potassium -rubidium -cesium -francium These metals are silvery solids with low densities and melting points.
What are denser harder have higher melting points and are slightly less active than alkali metals in the same period?
These are characteristics of alkaline earth metals, such as calcium and magnesium. They have tightly packed metallic lattices, making them denser and harder than alkali metals. Their higher melting points and lower reactivity compared to alkali metals can be attributed to their lower atomic size and increased nuclear charge.
What happens when the alkali metals react with chlorine?
They metals are stored in oil to minimize the reactivity with air. When alkali metals react with air, they quickly tarnish after begin cut, they burn easily.
Do transition have higher melting point than alkaline and alkali metals?
Yes, transition metals generally have higher melting points compared to alkaline and alkali metals. This is because transition metals have a greater number of valence electrons and a stronger metallic bond, which requires more energy to break and transition from solid to liquid. In contrast, alkaline and alkali metals have fewer valence electrons and weaker metallic bonds, resulting in lower melting points.
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
What is the effect of heat energy on alkali metals?
The melting point of alkali metals is low.
What is the Melting points of the alkali metals?
sodium
What is Properties of alkali metals?
Low melting and boiling point
Why the melting point boiling point and densities of alkaline earth metals are higher than alkali earth metals?
Alkaline earth metals do not exist , only alkali earth metals
How are the alkali metals different from the alkali earth metals in the periodic table?
The alkali metals have a valence of 1 while the alkaline earth metals have a valence of 2. The alkali metals are generally lighter, softer, more reactive, and have lower melting points than the alkaline earth metals.
How are the alkali metals different from the alkali-earth metals in the periodic table?
The alkali metals have a valence of 1 while the alkaline earth metals have a valence of 2. The alkali metals are generally lighter, softer, more reactive, and have lower melting points than the alkaline earth metals.

What are the key differences between alkaline earth metals and alkali metals?
Alkaline earth metals have two valence electrons, while alkali metals have one valence electron. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Additionally, alkaline earth metals are less reactive than alkali metals.

Is alkali metals can be cut simply by knife but iron cannot because of alkali metals have?
Alkali metals can be cut with a knife because they are soft and have low melting points. Iron cannot be cut easily with a knife because it is a strong and hard metal. The differences in properties between alkali metals and iron make alkali metals easier to cut with a knife.
