Name element 4
Chemical bonds that form between oppositely charged ions
Ability to dissolve in another matter
Name element 19

A massive explosion in which the entire outer portion of a star is blown off
The speed at which electrons flow past a certain point
When 2 materials rub together and transfer electrons, the result is a net-static charge on each material
HintAnswer
The distance light travels in 1 year, equivalent to about 63,000 AU or 9.5 x 10^12 kilometers
A star's total energy output per second; its power in joules per second (J/s)
A small, dim, hot star that takes tens of billions of years to cooldown, which will eventually become a black dwarf, however the universe is not old enough to contain any black dwa
A gauge to measure the energy in electrons in the circuit. Placed in parallel with a load. Requires two readings to calculate
Name element 20
Sunlight + carbon dioxide (CO2) + water (H2O) = oxygen (O2) + glucose (C6H12O6) + chemical energy
Oxygen (O2) + glucose (C6H12O6) = water (H2O) + carbon dioxide (CO2)
Name element 8
Name element 13
Name element 14
The state of shining by reflecting light
Chemical bonds in which one or more pairs of electrons are shared by two atoms
Phase 3 in Sigmoidal Growth:Resources become scarce, the population is still growing, but the reproductive rate has dropped
Any friction met in the circuit either by loads or by wires. Slows down the flow of electrons
Name element 10
Have less mass than the sun, they lose significant mass as they consume their hydrogen over a period that can be as long as 100 billion years.
Metals right beside the alkali metals or group 2. Slightly less reactive than alkali metals, but the second most reactive elements in the periodic table. Cations in their ionic for
Relationship between two species in which one kills and consumes the other
Relationship in which one species benefits while the other is left unaffected
Mass/ Volume, how compact something is
Materials that hold onto their electrons very strongly
A star with 12 or more solar masses is considered a __________?
Name element 2
Phase 2 in Sigmoidal Growth:Population begins to grow rapidly (exponentially)

Name element 16
Laws of Attraction: Neutral objects _______ charged objects.
Increase of toxin concentrations as they go up in trophic levels
Name element 1
Electrons on the outermost shell of an atom
consumes hydrogen much faster than low-mass stars, around 10 billion years. When they use up all their hydrogen, the core collapses, contracts and the temperature rises.
