Matter
Give an example of matter and non-matter.
non-matter - all others (heat, light, sound, etc.)
What table has all the elements?
The periodic table of elements.
Compounds are made of multiple _______, and mixtures are made of multiple _________.
elements, compounds
What is the center of the atom called?
the nucleus
Physical science is the study of _______ and _______.
Chemistry and Physics
Define matter.
Anything that has mass and takes up space.
Where can one find the atomic mass of an element?
At the bottom of the element symbol (under the name).
What would you call these molecules specifically? N2, O2, H2
diatomic molecules
What is the charge of the nucleus of an atom and why?
Positive, because there are protons and neutrons in the nucleus.
2 Fe3O2 --> How many iron atoms are there TOTAL in this molecule?
6
What branch of science studies matter?
Chemistry
What does the atomic number tell us about an element?
Its number of protons.
Matter is mainly classified in chemistry as ________, ________ or __________.
an element, a compound or a mixture
What are the three parts of the atom and what are their charges?
2. Electron (negative)
3. Neutron (neutral)
What are base units vs. derived units?
Base units are singular measurements. (g, m, etc.)
Derived units involve two or more measurements. (ex. m/s)
Is air matter and why/why not?
Yes, air is matter because it takes up space (has volume).
How do you calculate the number of neutrons in an element?
atomic mass - atomic number
Compounds like NaCl, H2O and CO2 are very specific in the number of elements they hold. This is because compounds must have exact ____________.
proportions
What is the outermost shell of electrons in an atom called?
the valence shell
What is reproducibility?
The reproducibility of an experiment refers to how well and accurately it can be performed by another scientist, and get the same/similar results.
What are the three ways matter are classified?
Element, Compound and Mixture
Come to the board and draw an element symbol. (where each part is located on the symbol)
drawn on board.
What are the two types of mixtures? Give an example of each.
heterogeneous and homogeneous
Come to the board and draw an atom of Helium.
drawn on board.
Define or give an example of an emergent property.
