What else can I help you with?
Are ions of alkali metals larger or smallest than ions of alkaline earth metals from the same period?
Ions of alkali metals are generally larger than ions of alkaline earth metals from the same period because alkali metals have only one outer electron, leading to a larger atomic radius and therefore a larger ion size compared to alkaline earth metals, which have two outer electrons.
A substance that has high reactivity is what?
A substance with high reactivity has the tendency to undergo chemical reactions easily with other substances. This can lead to the release of energy, heat, light, or gas in a relatively short period of time. Examples include alkali metals like sodium and potassium.
What is the name of alkali in period four of the periodic table?
Potassium is the alkali in period four of the periodic table. Its symbol is K.
What is an element with a single electron in its highest energy level is probably what type of metal?
An element with a single electron in its highest energy level is likely an alkali metal. Alkali metals like lithium, sodium, and potassium have one electron in their outer energy level, making them highly reactive and likely to form ionic bonds.
Why transition metals are different than the alkali and alkali earth?
it is because transition metals falls under differen group in the period table. Alkali elements falls in frirst group alkali earth metal falls in second group and the followed by groups are transition elemets
Is rubidium an alkaline-earth metal alkali metal transition metal or a semiconductor?
Rubidium is an alkali metal (group 1, period 5)
What type of metal will be for reactive than an alkaline earth metal in the same period?
alkali metal
Are ions of alkali metals larger or smaller than ions of alkaline metals from the same period?
larger
Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
Are ions of alkali metals larger or smallest than ions of alkaline earth metals from the same period?
Ions of alkali metals are generally larger than ions of alkaline earth metals from the same period because alkali metals have only one outer electron, leading to a larger atomic radius and therefore a larger ion size compared to alkaline earth metals, which have two outer electrons.
Are ions of alkali metals larger or smaller than ions of alkaline earth metals from the same period?
larger
Are ions of alkali metals larger or smaller than ions or alkaline earth metals from the same period?
larger
Alkali metal in period 3?
Sodium (Na) is the alkali metal in period 3 of the periodic table. It is located in group 1 and is known for its high reactivity with water and air. Sodium is commonly found in salts, such as sodium chloride (table salt).
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 alkali metal has the biggest radius?
The alkali metal. The alkali metal has less protons in the nucleus compared to the halogen in the same period and therefore exerts a relatively smaller attractive force on the outer-most shell electrons, enabling them to stray further away.
How do the valence electrons configurations of the alkali metals compare with each other?
The valance electron configuration is the same in each at ns1 where n = the period number.
How do the valence electron configurations of the alkali metals compare with others?
The valance electron configuration is the same in each at ns1 where n = the period number.
