Why are group 7 and group 1 elements usually found as compounds?
These elements are highly unstable because of for group1- IP is low and for group 7 electron affinity is high
Does aluminum have high or low density?
Aluminum has a density of 2. 7 grams per cubic centimeter. This makes it denser than hydrogen (0. 09 g/ml) and water (1. 0 g/ml), but much less dense than other metals such as titanium (4. 54 g/ml), copper (8. 96 g/ml), and lead (11. 35 g/ml). It is a relatively low-density element.
How long passing between high tides?

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.
What are the 7 classes of plastic?
The seven types of plastic are: Polyethylene terephthalate, High-density polyethylene, Polyvinyl chloride, Low-density polyethylene, polypropylene, Polystyrene, and an unnamed category consisting of plastics that do not fit into the other categories. Polystyrene is often called Styrofoam.

Is wood high tensile?
Wood has relatively low tensile strength - about 7 MPa (6000 psi) compared to say steel which is 70MPa (60,000 psi) or more.However, wood has a higher strength to weight ratio than most other materials since it has such low density.
What are 3 examples of Bose-Einstein condensation?
These examples are: rubidium-87, sodium-23, and lithium-7 as very low density gases at extremely low temperature.
What does the number on the bottom of recyclable products mean?
It refers to the type of plastic. 1 = polyethylene terephthalate (PET or PETE) 2 = high density polyethylene (HDPE) 3 = polyvinyl chloride (PVC) 4 = low density polyethylene (LDPE) 5 = polypropylene (PP) 6 = polystyrene (PS) 7 = Other
