Electrical Charges
What does the electricity coming out of a wall socket or a battery consist of?
The electricity from a wall socket or a battery consists of moving electrons.
What happens to a neutral atom when it adds or loses an electron?
It becomes an Ion.
How many electrons does sodium have in its outer ring?
One.
What is H on the periodic table
Hydrogen
What is Neon used for
Advertising lights
What is static electricity?
Static electricity is a collection of electrons, all repelling each other and ready to start flowing as an electrical current.
Why is each larger atom in the periodic table heavier than the one before it?
Because each larger atom adds a proton to the nucleus and another electron around the nucleus.
How many electrons does chlorine have in its outer ring?
Seven.
Ba stands for what on the periodic table
Barium
What is the plural for nucleus?
Nuclei
Why do two electrons circling the nucleus do so as a pair?
Electrons circling the nucleus pair up because they spin in opposite directions and in doing so, create opposite magnetic fields.
Which element do you need to make slime
Boron
Why do sodium and chloride ions bond together?
Because positive and negative always attract each other.
What is Calcium's abbreviation
Ca
What do we call negative electrical charges when they’re moving?
Electricity.
What are the electrons in the outermost ring called?
The electrons in the outermost ring are known as an atom’s valence electrons.
Why aren’t neutral atoms attracted to positive or negative ions?
Because neutral atoms are neither positive nor negative.
Why would sodium want to give its single valence electron to chlorine?
So that both sodium and chlorine can shed extra energy and become a lower energy state.
What is Magnesium's abbreviation
Mg
What do two positives do to two negatives?
They attract each other?😁
If the electrons are negative, and negative repels negative, why are electrons gathered together around the nucleus?
All the negative electrons stay together because they are all attracted to the positive nucleus.
Which element is used in welding to prevent oxygen from contaminating the weld?
Argon.
What happens to the electrical charge on the sodium and chlorine atoms when sodium gives its valence electron to chlorine?
The sodium atom becomes a positive sodium ion and chlorine becomes a negative chloride ion.
What is Na on the periodic table
Sodium
What identifies an element?
What identifies an element is the number of protons in its nucleus.
