Metals
Metals are generally good conductors of these two forms of energy.
What is heat and electrical energy?
This non-metal element exists as a diatomic gas, makes up approximately 78% of Earth’s atmosphere, and is essential in the structure of proteins in living organisms.
What is nitrogen?
This type of plastic is made partly or entirely from renewable biological materials, such as plants, rather than only from fossil fuels.
What is bioplastic?
This covalent substance is often called the “universal solvent.” In hydrogen fuel cells this is the waste product, hydrogen fuel cells helps us power rockets... that's why this is space stuff.
What is water?
This subatomic particle has a positive charge and is found in the nucleus.
What is a proton?
This property describes a metal that can be hammered or rolled into thin sheets without breaking.
What is malleability?
Non-metal atoms commonly form this type of bond by sharing electrons with other non-metal atoms.
What is a covalent bond?
This is the common name given to chemical compounds that have a metal ionically bonded to a non-metal.
What is a salt?
This is the stretching of light waves into longer, redder wavelengths as objects move away from us or as space expands.
What is red shift?
Atoms of the same element that contain the same number of protons but different numbers of neutrons are called this.
What is an isotope?
This soft alkali metal is stored under oil because it reacts rapidly with oxygen and water, its symbol is derived from the Neo-Latin word natrium.
What is sodium?
This element is a brown liquid non-metal at room temperature.
What is bromine?
This strong, lightweight form of carbon consists of a single layer of carbon atoms arranged in a hexagonal lattice.
What is graphene?
This is not an explosion in space, but rather the rapid expansion of space itself.
.
What is big bang theory?
This is the name of an electron which is furthest from the nucleus.
What is a valence electron?
Metals conduct electricity because these particles are free to move through the metallic lattice and carry charge.
What is delocalised electrons?
This noble gas is often used in light bulbs because it is very unreactive.
What is argon?
This mixture contains tiny particles of one substance dispersed throughout another, where the particles are larger than in a solution but do not settle out easily.
What is a colloid?
These pieces of equipment complete a full trip around the planet in just 90 minutes, meaning they circle the globe more than 16 times every single day.
What are low earth orbit satellites
This can be alpha, beta or gamma.
What is types of radioactive decay?
This is the most expensive metal on Earth.
What is Californium?
This non-metal element is essential in DNA, bones and energy transfer in cells. A red version of this element is found in the heads of matches to light them up.
What is phosphorous?
This process occurs when a metal gradually reacts with substances in its environment, such as oxygen and water, causing the metal to deteriorate.
What is corrosion?
This covalent compound is the primary component of quartz and many forms of sand. When it is melted at extremely high temperatures of 2000 degrees it can make glass.
What is silicon dioxide?
This is the charge on an atom that has 15 protons, 18 neutrons and 18 electrons. BONUS point for naming the element.
What is negative 3? What is Phosphorous?
