Atoms
What is the subatomic particle found in an atom with a positive charge?
Proton
What is the "A" in the AZX formula for a periodic table
Atomic mass
What is radioactive decay?
It is when an atom has too many subatomic particles or energy, and must shed this.
If something is a 2 on the ph scale, is it acidic or basic?
Acidic
What is a product?
What is the subatomic particle in an atom with a neutral charge?
Neutron
What is the "Z" in the AZX formula of a periodic table?
Atomic number
What is an alpha particle?
A form of radiation where the atom shed two protons and two electrons.
If something is a 10 on the ph scale, is it acidic or basic?
Basic
What is a reactant?
Something that goes through a chemical reaction, the before item
What is the subatomic particle with a negative charge?
Electron
What is the "X" in the AZX formula of a periodic table?
Element
What is a beta particle?
What do I get if I mix an acid with a base?
Neutralised salt and water
Say this as a word equation: potassium hydroxide and sulfuric acid yield potassium sulfate and water.
Potassium hydroxide + sulfuric acid --> potassium sulfate + water
What happens to an atom if it gains more neutrons?
It becomes a different type of isotope
What are the columns and rows called in a periodic table?
Groups and periods
What is a gamma ray?
A form of radiation that is a ray of energy given off by a decaying atom
What ph is pure water?
7
Is this balanced? Xe + F2 --> XeF6
No, this is unbalanced.
What happens to an atom if it gains more protons?
It changes element
How do you work out the amount of neutrons in an element?
Atomic mass - the atomic power
Name three uses for radiation in the real world
Examples: power, cleaning, cancer treatment, smoke detectors, reflective paint, military
What substances are produced when you mix acid with a metal?
Salt, water and hydrogen
Say how many atoms are on each side of this equation: N2 + 3H2 --> 2NH3
This is balanced. N=2, H=6
