Will group 2 metals of the periodic table sink?
Yes. They have very high densities, such as 1847.7kg/m3 for beryllium.
Why the metal elements are hard?
have very high density and have high atomic mass
Is it true that not all elements can be in the form of gas?
That is not true. Every element takes the form of a gas if it is sufficiently heated. In other words, all elements have some boiling point. For some elements the boiling point is very high, but it does exist.
You are having to reset your electric water heater breaker daily?
Likely one of the two electric elements is going out which creates very high resistance in the circuit and therefore draws very high current (amps) and causes the breaker to trip.
What is the density of rubber stopper?
The density of rubbers stoppers can be very different from one to the next. This is because there are different stoppers at different densities.
Will group 2 metals of the periodic table sink?
Yes. They have very high densities, such as 1847.7kg/m3 for beryllium.
Why do minerals have the nonsilicate crystalline structure called closest packing have high density?
The native elements have very high desities because their crystal structures are based on the packing of atoms as close together as possible
Is low density a metal or nonmetal?
Generally, metals have a high density relative to other elements, but there are a few which dont correspont to this rule. But if it was a simple yes or no question, it would be HIGHH!!!! The density of metals is very variable: from lithium (0,534 g/cm3) to osmium (22,61 g/cm3) - from low density to high density.
Why the metal elements are hard?
have very high density and have high atomic mass
What happens to elements at very high temp?
They get hot. If "very high" is high enough then they start existing as a fourth state of matter called "plasma". If "very high" is even higher than that they could break down into a quark-gluon plasma.
What are examples of high reactivity?
Very reactive elements are alkali metals and halogens.
What conditions metamrphic rocks form?
the conditions are very high heat (hot enough to melt the rock), and/or very high pressure (to recombine the elements in the rock).
What is the similarity between plasma and Bose-einstein condensates?
Plasma is heated to a very high temperature. Bose Einstein Condensates cool to very low densities."BOTH ARE/HAVE TOO EXTREME TEMPERATURES."
What is the heaviest naturally element?
Either osmium or iridium. The densities are very close.
Why do minerals that have the nonsilicate crystalline structure called closest packing have high density?
Minerals of a nonsilicate crystal have very high densities because their crystal structures are based on the packing of atoms that are as close together as possible. This structure is called this closest packing.
What happens with fusion of heavier element?
Heavier elements - mainly, elements with an atomic number after that of iron - will only fuse at very high temperatures, mainly in supernovae.
Why are group1 and 7 found as compounds?
Group 1 elements have very low electronegativies and group 7 elements have very high electronegativities, so that both are reactive with almost every other element, the group 1 elements by donating electrons and the group 7 elements by accepting electrons.
