Alkaline earth metals do not exist , only alkali earth metals
Because these metals are very reactive and readily form compounds.
they are harder than alkali metals
Because these metals are very reactive and readily form compounds.
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).
Exposure to heavy metals in water can cause symptoms such as nausea, vomiting, diarrhea, abdominal pain, neurological issues, and in severe cases, organ damage.
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).
They generally oxidize with exposure to the moisture in air, producing rust.
A rare disorder caused by vitamin D deficiency or exposure to heavy metals.
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.
Cumulative exposure to mercury, lead and their compounds, and other metals caused him to die
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.
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.
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.
Near the sea exposed metals have a greater exposure to salts, which accelerate the rusting process.
No, not all metals are safe for humans. Some metals can be toxic when ingested or inhaled in high amounts, such as lead, mercury, and arsenic. It is important to be aware of the potential risks of exposure to certain metals and follow safety guidelines to minimize any negative health effects.
Yes, heavy metals can pass through the placental barrier and reach the developing fetus. This can lead to harmful health effects on the fetus, as exposure to heavy metals like lead, mercury, or cadmium during pregnancy can interfere with normal development and cause long-term health issues. It is important for pregnant women to avoid exposure to sources of heavy metals to protect the health of their baby.
