Energy
What is one of several distinct regions around the nucleus of an atom where electrons are found?
An energy level.
What is the average mass of all the isotopes of an element known as?
The atomic mass.
What is the number of protons found in an atom known as?
The Atomic Number.
What subatomic particle has a positive 1 charge, is found in the nucleus of all atoms and has a mass of 1 AMU?
A proton
What is the force that holds the nucleus together?
The Strong Force.
Electromagnetic radiation that can be seen with the unaided eye is known as.
Visible light.
What is the atomic mass unit (equal to 1.66053892 × 10-27 kilograms) known as?
The AMU.
What is the region around the nucleus of an atom where electrons are likely to be found known as?
The electron cloud.
What is the center of the atom known as? (Composed of protons and neutrons. Contains 99.9% of the mass of the atom.)
The nucleus
What is the force of attraction between all masses in the universe known as?
Gravity.
Daily double - Not energy
What is a hypothesis that has been tested with a significant amount of data known as?
Daily double - Not energy
A Theory
What is the term used to describe a minus charge on a particle?
Negative
What is the subatomic particle that has a negative 1 charge and is found outside the nucleus in the electron cloud with a mass of 1/1836 AMU?
The electron.
What is a charged atom known as?
An Ion.
What is known as a push or pull?
A force
What has no mass or weight, no electrical charge, travels at speed of light as both a particle and a wave? (Common name is light when in the visible range.)
Electromagnetic Radiation.
An object that has no positive or negative charge is known as? (No charge)
Neutral.
What is the region of space around the nucleus where an electron is likely to be found?
The orbital.
What is the name of the particle known as a tiny bundle of light energy?
A photon
What is the force associated with charged particles such as protons and electrons and has two aspects, electric and magnetic force? (This force keeps electrons around the nucleus of an atom.)
The Electromagnetic Force
What is energy that is radiated or transmitted in the form of rays or waves or particles known as?
Radiation.
What is evidence gathered without actually seeing it, (based on how things behave around it rather than the object itself)?
Indirect Evidence
What subatomic particle is found in the nucleus of all atoms?
A proton.
What is an atom of the same element that has different numbers of neutrons than average and therefore a different mass than the average atom of that type?
An isotope.
What is the force that allows the nucleus to 'split' into multiple smaller nuclei as it releases energy? (We call this splitting nuclear fission.)
The Weak force
