scientific method
After doing some research but before conducting your experiment, this step in the process ensures we take an educated guess.
What is "Develop your hypothesis"?
The four states of matter.
What are solid, liquid, gas, and plasma?
The elements on the periodic table are arranged by this.
the three parts that make up an atom.
What are the protons, neutrons, and electrons?
atoms with the same number of protons but different number neutrons
What are isotopes?
when you use your five senses- sight, sound, taste, smell, and touch.
What is make an observation?
when atoms/molecules have some space to move around because they are not tightly connected
What is a liquid?
It has 80 protons.
What is mercury?
The part of the atom that is positively charge.
What are the protons?
What the name is of an atom that has 29 protons and 37 neutrons.
What is copper-66?
examples include: time, temperature, amounts, mass, etc. but don't include things like color, texture, or shape
What are quantitative observations?
when a gas becomes a liquid.
What is condensation?
It has a mass of 175 and therefore has this many neutrons.
What are 104 neutrons (element= Lutetium, #71)?
Where the electrons are located.
What is orbiting the nucleus of the atom?
The reason why bromine can have a -1 charge.
What is Bromine gains an electron?
When evidence is used to support your claim to an experimental question?
What is "reasoning"?
The two things that all matter has.
What are mass and volume (they take up space)?
This neutral atom has 93 electrons.
What is neptunium, Np?
The parts of the atom that the mass is based on.
What are the protons and neutrons?
The most common version of palladium, Pd.
What is Palladium-106?
The three parts of a claim.
Made of elements and/or compounds in varying amounts but its appearance is the same throughout
What is a homogeneous mixture?
The other pure substance that contains different elements in certain ratios.
What is a compound?
The reason atoms become positively or negatively charged.
What are electrons?
When an atom has 22 protons, 26 neutrons, and 18 electrons, this is its atomic mass and charge.
What is an atomic mass of 48 and a charge of +4?
