Subatomic Particles
I am the positive particle inside an atom.
What is a proton?
I am made up of at least two combined atoms, even if they are the same element.
What is a molecule?
This physical property is used to describe metals that are bendable are said to be this.
What is malleable?
This chemical property describes how easily a substance will burn?
What is flammability?
This is the name given for the time it takes for half of a radioactive substance to decay.
What is half-life?
I am the only particle in an atom with neglibible (really small) mass.
What is an electron?
I consist of two or more different elements combined to make one substance.
What is a compound?
This is what happens to the density of a substance if you cut a slice off of it.
What is nothing?
This word is s synonym for burning.
What is combustion?
Radiation is the emission of this from a nucleus.
What is energy?
Empty space accounts for 99% of this.
What is an atom?
I am made up of one charged atom.
What is a monoatomic atom?
This physical property does not change if a substance is taken to the moon, and is determined by the number of atoms or molecules in a substance.
What is mass?
This chemical property describes how easily a chemical will interact with other chemicals.
What is reactivity?
If a nucleus is too big to hold itself together, it is described as this.
What is unstable?
I am the only subatomic particle that is not in the nucleus.
What is an electron?
I am made up of two or atoms and am charged.
What is a polyatomic ion?
This physical property is used to describe metals because they allows electrons to flow through me easily.
What is conductor?
I am the element always written first in any binary compound.
What is the element further to the left on the periodic table?
An isotope that randomly emits radiation is said to be this.
What is unstable?
I am the largest subatomic particle, and I am also located in the nucleus.
What is a neutron?
I am made up of two identical atoms.
What is a molecule?
This physical property is inversely proportional to an object's distance from the earth.
What is weight?
Two elements with the same oxidation numbers combine to form a binary compound, but one positive and one negative. This identical subscript would be assigned to each of them.
What is a one?
This is the number of isotopes of plutonium (atomic number 94) are stable.
What is none (or zero)?
