I have 3 energy levels and 1 electron in my last energy level, what am I? Sodium
What do you think the differences are between physical and chemical properties/characteristics? The difference is that one is a solid and one is a liquid. Physical properties can be seen and felt. Chemical properties make up physical properties through cells.
Why is the grass green? When the sun’s rays hit the grass it absorbs the 6 of the 7 color rays but reflects a green color.
What are Rainbows? Rainbows are an illusion caused by the sun’s white rays being seperated into 7 colors when they touch the water in the air.
The Periodic Table of Elements is most what kind of Elements? Metals.

Define the charge, how to find how many are in an element, and the location of a proton in an element?
The charge of a proton is positive, the amount of protons in an element is the same as the atomic number and it’s found in the nucleus.
If an element has a charge of +1 how do you find the amount of electrons it has? You take the electrons and subtract one from the number of electrons.
Groups aren’t part of which type of elements? Transition Elements
What are valence electrons? Electron in the elements last energy level
How do you find how many energy levels an element has? By the period the element is in

How many protons, electrons, neutrons, energy levels and valence electrons does boron have. a= p5 e5 n6 el2 ve3
Give 3 examples of matter and 3 examples of energy a= matter: table, pencil, notebook energy: heat, electricity, wind
What element is in group 9 and period 7 a= meitnerium
what period and group is radon in
name one metalloid a= boron

What creates rainbows? Raindrops splitting sunlight gives off a color.
What is an Ion? an ion is the + or- charge of an atom.
What are three examples of energy? Three examples are heat, wind, and electricity.
What is an example of the law of conservation of matter? An example is when you add salt to warm water the salt dissolves into the water but it is still there. The matter is neither created nor destroyed.
What are three differences between metals and non-metals? Three differences are metals are good conductors, metals are malleable, and are ductile.

1.) What are the horizontal rows on the periodic table called, and what do they tell us about the elements found in that “row?”
A.) The rows are called periods. The period of an element indicates how many energy levels it has.
2.) What two parts of an atom are added together to get the atomic mass?
Protons and neutrons are added together to get the atomic mass.
3.) What are the columns on the Periodic Table called, and what groups do they indicate?
A: The columns on the Periodic Table are called groups and they indicate how many electrons can be found in the last energy level of the elements in the same group.
4.) What part of an atom contains the most mass? Why?
A: The nucleus is the part of an atom that contains the most mass. Protons and neutrons are found in the nucleus and they are the most massive part of an atom.
5.) The Periodic Table is divided into three sections , metals, metalloids, non-metals. Where can each section be found on the Periodic Table?
A: Metals can be found to the LEFT of the stair step. Metalliods are found on the stair step. Non-metals are found to the RIGHT of the stairstep.?

1. How many parts are there to an atom?
Answer: The parts are the nucleus, electrons, electron cloud, and the energy level.
What am I? I have 9 protons and 10 neutrons.
Answer: I am Fluorine!
What is an Ion?
Answer: An Ion is a type of element with extra or less electrons.
4. How is the periodic table organized?
Answer: The periodic table is organized by the elements atomic number. It goes from least to greatest.
5. Anything that has mass and volume is what?
Answer: Matter is anything with mass and volume.
List 3 Examples of Energy.
- wind
sugar rush
heat
light
The Law of Conservation of Matter is what??
The Law of Conservation of Matter is that matter is neither created nor destroys. It just changes form.

October 27th, 2008 at 1:10 pm
questions-
1. what is isotope? - the charge of electron that loses electron +
2. How is the water cycle a Law of conservation of matter? - the atoms doesn’t go away is just changes to a different form and come back.
3. give some characteristic of metal element.- metals are luster, and conductivity to electricty and heat
4. what is not a characteristic of a non metal?- luster
5. what is word for -1 charge?- ion.
