What else can I help you with?
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
Why are neither the alkali metals nor the alkaline earth metals found in nature?
Because these metals are very reactive and readily form compounds.
What are characteristic property of the alkaline earth metals?
they are harder than alkali metals
Why are neither the alkali metals nor the alkaline-earth metals found uncombined in nature?
Because these metals are very reactive and readily form compounds.
How does the hardness of the alkaline earth metals compared to the hardness of alkali metals?
Transition state metals include a wide variety of metals; they include iron, gold, and mercury which all have strikingly different properties (hard, soft, and liquid, for example). Nonetheless, a comparison can be made between the transition state metals and the alkali and alkaline earth metals; transition state metals are not as chemically active (some transition state metals are actually inert, such as platinum).
Could poisoning cause arthritis?
Poisoning itself does not directly cause arthritis, but exposure to certain toxic substances can lead to inflammatory reactions that may contribute to joint pain or conditions resembling arthritis. For example, heavy metals like lead or mercury can cause systemic inflammation and joint issues over time. Additionally, some environmental toxins may trigger autoimmune responses, potentially leading to arthritis-like symptoms. However, the relationship between poisoning and arthritis is complex and varies depending on the specific toxins involved.
What are the symptoms associated with exposure to heavy metals in water?
Exposure to heavy metals in water can cause symptoms such as nausea, vomiting, diarrhea, abdominal pain, neurological issues, and in severe cases, organ damage.
Explain Trace metals Heavy metals Give examples?
Poisoning and disease can occur due to human exposure to trace quantities of heavy metals. Common trace metals include mercury (Hg), arsenic (Ar) and lead (Pb).
Name a disadvantage of ferrous metals?
They generally oxidize with exposure to the moisture in air, producing rust.
What is fanconi syndrome?
A rare disorder caused by vitamin D deficiency or exposure to heavy metals.
Do heavy metals cause autism in children?
There is no scientific evidence to suggest that heavy metals cause autism in children. Autism is a complex neurodevelopmental disorder with a combination of genetic and environmental factors contributing to its development. While exposure to heavy metals can have negative health effects, there is no direct link between heavy metal exposure and autism.
Why did Karl Scheele die?
Cumulative exposure to mercury, lead and their compounds, and other metals caused him to die
What is the least corrosive metals?
Some of the least corrosive metals include gold, platinum, and titanium. These metals are highly resistant to corrosion and oxidation, making them ideal for applications where exposure to harsh environments is a concern.
How do you get heavy metals in your body and what are the potential health risks associated with their presence?
Heavy metals can enter the body through contaminated food, water, air, or exposure to certain products. When present in high levels, heavy metals like lead, mercury, and arsenic can cause serious health risks such as organ damage, neurological issues, developmental delays, and even cancer. It is important to limit exposure to heavy metals to protect overall health.
How metals change due to exposure to the air?
Some metals, namely iron, oxidize (that is the metal loses electrons) in the presence of air. This causes a chemical change to iron oxide, which is responsible for rusting.
WHAT HAPPENS TO METALS WHEN IT IS EXPOSED TO VINEGAR IN 1 DAYS?
When metals are exposed to vinegar, which contains acetic acid, a chemical reaction may occur, particularly with reactive metals like iron and aluminum. This can lead to corrosion or the formation of metal salts, resulting in rust or tarnish. Non-reactive metals, such as stainless steel or gold, typically show little to no change after one day of exposure to vinegar. However, prolonged exposure can still cause some surface etching or dulling.
How does living near the sea contribute to rusting?
Near the sea exposed metals have a greater exposure to salts, which accelerate the rusting process.
