The concentrations of metals are typically higher in freshwater than in seawater because freshwater systems have less capacity to dilute or transport metals compared to seawater. In freshwater systems, metals can be sourced from natural weathering of rocks and human activities, and they accumulate as there is less water volume to disperse them. Conversely, in the vast volume of seawater, metals are more dispersed and diluted.
What else can I help you with?
Are alkali Metals often found as pure elements in seawater?
No, alkali metals are not typically found as pure elements in seawater. Instead, they are predominantly found in ionic forms, such as sodium (Na⁺) and potassium (K⁺), due to their highly reactive nature. When exposed to water, alkali metals react vigorously, which prevents them from existing as free elements in natural environments like seawater.
What are the other sources of metals other than ores?
Metals can also be sourced from recycling scrap metal, by extraction from seawater or from deep-sea deposits, and by recovering metals from electronic waste. Additionally, metals can be sourced from meteorites that have fallen to Earth.
True or false Every know naturally occurring element is found in at least trace amounts in seawater?
True. Every naturally occurring element on the periodic table has been found in at least trace amounts in seawater, largely due to geological and biological processes. While some elements may be present in very low concentrations, they can still be detected. This includes metals, nonmetals, and metalloids, reflecting the ocean's complex chemistry and interactions with the Earth's crust.
Are alkali metals often found as pure elements in sea water?
Alkali metals are not typically found as pure elements in seawater. They are highly reactive and tend to form compounds with other elements rather than exist in their pure metal form. However, trace amounts of alkali metals may be present in seawater due to natural processes or human activities.
What organisms does phytonmining?
Plants are the organisms used for phytomining. If plants can absorbs the low concentrations of metals in soil, the metals can be concentrated in the biomass of the plants and then extracted from the plant material when harvested.
Why are so few metals extracted from sea water?
Most metals are not in any economic concentrations in seawater. The only exceptions are sodium and magnesium. A company did start up trying to extract lithium from seawater but it went bust but the technology will certainly be looked at again when lithium is needed in large amounts for making batteries. Bioengineering technology may be used in the future to get bacteria and algae to concentrate metals from seawater.
Do heavy metals impact on freshwater turtles and how?
yes and they crack the shells.

Where can you find alkaline-earth metals?
Alkaline-earth metals can be found in the Earth's crust, primarily in minerals such as limestone, dolomite, and gypsum. These metals are also commonly present in seawater and in various ores, such as magnesite and beryl.

Do metals or non metals have higher electronegativy?
In general, non metals are more electronegative
What effect does seawater have on metal?
Metals corrode because electrons are stolen from or donated to them by other compounds in the neighborhood ,typically other metals. Salt water conducts better than fresh.
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 organisms does phytonmining?

What has the author K G Compton written?
K. G. Compton has written: 'The effect of aerobic marine bacteria on the corrosion of metals in sea water' -- subject(s): Metals, Microbiology, Seawater corrosion
What are conductivity metals?
Metals have a higher electrical and thermal conductivity than nonmetals.
