Is gold powdery or brittle?
It depends on how much foreign metals it may have,pure gold is soft and malable like lead
When the lead acid battery produces electricity both electrodes become coated with solid what?
They become coated with lead sulfate.
Why does the polonium (po) become lead (pb) after a decay?
Polonium-210 lose an alpha particle and become lead-206.
Is PbS metallic?
No, Lead Sulfide (galena) is a brittle crystalline solid with semiconducting properties.
What are the properties of lead sulfide?
Sulfides such as pyrite (feS2) are compounds of sulfur and one ore more elements.
Are teeth brittle?
Healthy teeth should NOT be brittle. Instead, they should have healthy enamel. A thick enamel makes teeth strong and bright white. Teeth without enough enamel look off-white or gray, and can become brittle. This lack of enough enamel can lead to tooth weakness, cracking, and breakage.
Does lead evaporate?
At high enough temperatures, yes.
How does age affect our bones?
As we age, our bones tend to become less dense, making them more susceptible to fractures and breaks. This can lead to conditions like osteoporosis, where bones become brittle and fragile. It's important to maintain a healthy lifestyle with adequate nutrition and weight-bearing exercise to help slow down the natural aging process of bones.
Does lower temperatures lead to slower soil formation?
yes
How and when was the element lead discovered?
Worked lead was dated back as far as 6400BC. Its discovery is not documented, but it melts at fairly low temperatures so it would be possible to work it at fireplace temperatures.
How thick is pencil lead?
Pencil lead is a brittle solid and it is graphite made in different hardness's. The thickness and shape of the actual rod of graphite can vary greatly
Do greenhouse gases lead to freezing temperatures at the south pole?
No. Greenhouse gases trap the sun's heat, so they lead to warmer temperatures all around the world, including at the south pole.
What is is osteoporosis?
Osteoporosis is a condition where bone creation is outpaced by bone loss. This causes bones to become brittle, and even mild stresses can lead to fracture. Osteoporosis can affect anyone, but white and Asian women past menopause are at highest risk.
Is gold powdery or brittle?
It depends on how much foreign metals it may have,pure gold is soft and malable like lead
Is it true lead and gold both freeze at low temperatures for metals?
Yes
What steps lead to forming a metamorphic rock?
Existing rocks are buried and subjected to heat and pressure. This causes them to recrystallise without melting.
Does metallic have a high melting point?
Not all of them. Mercury is liquid at room temperature. Bismuth and lead melt at relatively low temperatures.
