Yes.

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 are denser harder have higher melting points and are slightly less active than alkali metals in the same period?
Alkali metals are very chemically reactive, are not dense or hard metals and have low melting points.
What is the effect of change in pressure in melting point?
Putting a substance under pressure increases its melting point because substances expand as they melt. Putting them under pressure makes it harder for them to expand, which means that they require more energy (heat) in order to transition from a solid state to a liquid state. If a substance is under pressure, decreasing the pressure will lower its melting point.
When magma cools minerals with higher melting points will?
Minerals with higher melting points will crystallize.
Explain why alkali metals have a greater affinity for electrons than alkaline earth metals?
They don't, they actually have a greater tendency to lose electrons. This is for a number of reasons. First of all, the alkali metals form a stable cation by losing one electron, while the alkaline-earth metals need to lose two to form a stable ion. It takes more energy to remove one electron from an atom than it does to remove two. Additionally an alkaline earth metal has a greater positive charge on its nucleus and a smaller atomic radius than an alkali metal in the same row of the periodic table. This make it even harder to remove valence electrons. ------------ ?? WRONG: Alkali metals have a valence electron configuration of ns1 so they can accept another electron in the ns orbital. On the other hand, alkaline earth metals have a valence electron configuration of ns2. Alkaline earth metals have little tendency to accept another electron, as it woudl have to go into a higher energy p orbital.
WHat has a ph of 8 or higher?
alkali :)it is right :0
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
What happens when an alkali pH number is higher than 7?
It is normal for an alkaline solution to have a pH higher than 7.
Do most transition metals have higher or lower melting points than the representative elements?
Yes, transition metals have higher melting points. This is due to having very strong bonds. This means that a larger amount of energy is needed in order to break them down or bring them to the melting points.
First ionisation energies of alkaline earth metals are higher than those of alkali metals?
Yes, they are.
Is oven cleaner alkali or a acid?
Oven cleaners are high in alkaline, ranging from 10 to 14 pH.The higher it is, the cleaner the oven is
What are denser harder have higher melting points and are slightly less active than alkali metals in the same period?
Alkali metals are very chemically reactive, are not dense or hard metals and have low melting points.
Blood has a pH of 7.35 to 7.45. gastric juice has a pH of about 2.0. the more alkaline fluid is?
Higher is the pH value more alkaline is the fluid so Blood is more alkaline.
Why do metals share properties with other transition metals in their period?
The physical properties of transition metals are determined by their electron configurations. Most transition metals are hard solids with relatively high melting and boiling points. Differences in properties among transition metals are based on the ability of unpaired d electrons to move into the valence level. The more unpaired electrons in the d sublevel, the greater the hardness and the higher the melting and boiling points.
Does alkaline solutions have pH values below 7?
The higher the pH value the higher the Alkaline concentration.
What is alkalinity and its relation to the pH scale?
The pH scale is mostly in the range 0-14. A pH value of 7.0 means neutral. The lower the value, the more acidic the substance. The higher the value, the more alkaline. Note that, pH can be 15, just like it can be -1.
Salts of alkaline earth metals are less soluble than salts of alkali metals because?
A higher cation charge concentrated on the smaller cations makes it hard to pull apart ionic lattices
What is the characteristics of alkaline?
* alkaline metals contain the higher melting and also the boiling points. * These metals are present in the earths crust which does not have a basic form. * Alkaline earth metals are distributed in structure which is named as rock. * These metals have density which is low. * Alkaline earth metals have low electron affinity and as wells as low electronegativity. * One of the basic characteristic is, it contains two electrons in their outer shell.
