and Matter
Anything that has mass and takes up space. Everything is made up of this?
What is matter?
Solubility, ductility, conductivity, and viscosity are examples of this property.
What are physical properties?
These particles have positive and neutral charges and are located in the nucleus.
What are proton and neutrons?
This law organizes the elements on the periodic table in order of increasing atomic number so that elements with similar physical and chemical properties are aligned.
What is the Periodic Law?
This term is used for the electrons in the outermost shell.
What are valence electrons?
A theory that describes the composition and behaviour of matter. There are also 5 main ideas that summarize this theory.
What is the particle theory of matter?
Numerical values like temperature and height are categorized in this property. For example: 20 cm high or boils at 100 degrees celsius. (Be specific!)
What are quantitative properties?
If you subtract the mass number of an element from the number of protons you get this value. ( Mass - protons = ?)
What is the number of neutrons?
This corresponds to the number of electron shells and increases as you go down the periodic table.
What is a row/period?
This man made the plum pudding model and proposed that atoms contain electrons.
Who was Thomson?
Solid, liquid and gas.
What are the states of matter?
A characteristic behaviour that occurs when the substance changes into something new.
What is a chemical property?
Element X has 16 protons and a mass of 32. Determine the Element.
What is Sulfur?
These metals are very reactive, shiny, soft and solids at room temperature.
What are Alkali Metals?
A gas test with this specific gas starts with a burning splint, makes a 'pop' sound and then the flame gets extinguished.
What is hydrogen.
This category of matter is made up of a combination of different kinds of particles. There are also 2 types of this matter...
What is a Mixture?
What change is represented in this photo?
What is a chemical change?
In standard atomic notation, this number is represented at the top of the element's symbol.
What is the mass number?
They have a full octet shell, are very stable and non-reactive.
What are noble gases?
I am a ratio of mass to volume.
What is density?
This is an example of what type of mixture?
What is a homogenous Mixture?
Ms. Vuletic is baking a cake. She mixes 2 cups of flour with cocoa powder, baking powder, baking soda, and sugar and creates a mixture of dry ingredients. She then mixes the wet ingredients with hot water. After baking it for 40 minutes the cake is ready to eat! This is what type of change?
What is a chemical change?
This subatomic particle gives the identity of the element.
What are protons?
This element can act like both a metal and a non-metal.
What is hydrogen?
This is the Bohr rutherford diagram of an element.
What is sodium?
