What bomd is formed when atoms share electrons?
When they share electrons it is covalent because they are codependent on each other, and ionic bonding is when they give electrons to another or receive electrons from another. that's how i remember it. Hope that helps :) x
How many electron are there in one kilogram of electron?
The idea is to divide 1 by the mass of the electron, in kilograms.Note that you'll never get 1 kg of electrons (just by themselves) close together - the electrostatic repulsion would be enormous.
How many valence are in chlourine?
A total of 7 valence electrons. If I remember correctly, the number of valence electrons of all group A elements are designated by their group number. Chlorine is in group VIIA, hence 7 valence electrons.
How many electrons are lost or gained in the element o when they form ions?
atoms gain and lose electrons, so they can have a full outer shell of 8 electrons (or two electrons if its the innermost shell) when atoms lose electrons it is called oxidation and when they gain electrons they are said to be reduced. OIL RIG is most commonly used to help remember that oxidation is loss and reduction is gain of electons. when atoms lose electrons they are left with a positive charge and when they can electrons they have a negative charge.
Concept of oxidation and reduction?
a reversible chemical reaction in which one reaction is an oxidation and the reverse is a reduction
What is the percentage by mass of nitrogen in ammonium phosphate NH43PO4. Remember a subscript outside parentheses is multiplied by every subscript inside the parentheses?
28.2%
What the mnemonic for doing parentheses in math problem?
I've heard PEMDAS as Please Excuse My Dear Aunt Sally, but all you have to remember is that parentheses are first.
Which calulation will be performed first in a formula that does not contain parentheses?
i think exponents? remember, PEMDAS?
Does period come before or after parentheses?
no! for exampleThirty-five years after his death, Robert Frost (we remember him at Kennedy's inauguration) remains America's favorite poet.Thirty-five years after his death, Robert Frost (do you remember him?) remains America's favorite poet.Thirty-five years after his death, Robert Frost remains America's favorite poet. (We remember him at Kennedy's inauguration.)
What is a way to remember the properties of math?
All i know is how to remember associative property. In associative property you can have the parentheses in between any numbers and it will be the same answer.
What are the electrical charges of protons and electrons?
Protons are positive, remember pro is +. Electrons are negative.
What is the math rule that you always remember?
The precedence rule PEMDAS which is a mnemonic for Parentheses Exponentiation Multiplication Division Addition Subtraction
How do you do the order of operations for integers?
Remember PEMDAS; please excuse my dear aunt Sally. Parentheses, exponents, multiply, divide, add, and subtract.
How many electrons are in its outer energy level for Magnesium?
There are 2 outer shell electrons in Magnesium. Remember, it's in the "s" orbital, which can only accomodate 2 electrons.
How to you never forget your manners?
Remembering your manners is all about respecting those around you. Constantly remember that. If you remember that, you will remember the common knowledge of manners.
If an element has 12 protons and 13 neutrons how many electrons dose it have?
12 electrons. Remember, electrons and protons must be balanced in charge; neutron number may vary.
A catchy way to remember how to use parentheses?
In multiplication PEMDAS P= Pretty E= Elizabeth M= Marries D= Dummy A= Adam S= Sandler
