What is the oxidation number of Li in Li2?
The rule for hydrogen is that it normally has an oxidation state of +1, EXCEPT in metal hydrides, when it has an oxidation state of -1.Li is a metal, LiH is a metal hydride.Does that tell you what you need to know?
What does the oxidation number tell you about an atom?
The oxidation number of an atom indicates the number of electrons it has gained, lost, or shared to reach a stable configuration. It provides information on an atom's electron distribution and helps predict its reactivity in chemical reactions.
What does the oxidation number tell you about an ion?
It tells u how many of that ion there is for that substance or item. Have a great day.
How can you tell an elements oxidation number by looking at the periodic table?
1. Elements on their own have an oxidation # equal to 0. (ex. in the chem equation Ca + 2AgCl --> CaCl2 +2Ag, Ca and 2Ag would have oxidation #s equal to 0.) 2. Ions in ionic compounds have an oxidation # equal to their charge. (ex. in the chem equation Ca + 2AgCl --> CaCl2 +2Ag, 2AgCl = Ag+1 and Cl-1, and CaCl2 = Ca+2 and Cl2-1.)
How do you tell if an ion is positive or negative from a diagram?
In a diagram, positive ions are typically represented with a plus sign (+) next to the element symbol, while negative ions are represented with a negative sign (-). Additionally, positive ions usually have fewer electrons than protons, resulting in an overall positive charge, while negative ions have more electrons than protons, resulting in an overall negative charge.
How do you tell which is greater a negative number or a positive number?
a positive number is always greater than a negative number
How can you tell which is positive and which is negative by numbers?
the number that has the minus sign in front of it is negative and the normal number is positive example: negative: -9 positive: 9
How can you tell from the number of factors when a product is positive or negative?
If you are multiplying negative numbers, an odd number of factors will have a negative product. An even number of factors will have a positive product.
If you add a positive and a negative number how can you tell whether the answer will be positive negative or equal?
If the negative number is bigger then the answer will be negative If the bigger number is positive then the answer will be positive. All you do is subtract the two numbers and take the sign of the bigger number Ex (+2)+(-7)=(-5)
How can we tell without calculating whether the sum of a positive number and a negative number will be positivenegative or zero?
To determine the sum of a positive number and a negative number without calculating, we can compare their absolute values. If the absolute value of the negative number is less than the positive number, the result will be positive. If the absolute value of the negative number is greater than the positive number, the result will be negative. If they are equal, the sum will be zero.
What are 4 different ways you can tell the difference between positive and negative integers?
1. a negative number has a minus(-) sign before the number. 2. A negative number is always below zero.
When adding two integers how can you tell if a sum will be positive negative or zero without actually adding?
if your negative number is higher than your positive number your sum will be negative. if it is 0 i think that's pretty easy to find out yourself. ex: -5-3 = -8
How can you tell what side is negative and what side is positive?
Large side is negative
How do you know positive and negative terminals?
Look for a + by the positive terminal and a - by the negative terminal, or red for positive, black for negative. Some batteries have the positive terminal protruding and the negative terminal flat. Or you can get a meter that will tell you which is which,
How can you tell if an electroscopic is negative or positive?
if it repells its negitive if it attracts its positive
How can you tell about two integers when their quotient is positive negative zero?
If both integers are positive or both negative then the quotient is positive. If they are one of each then the quotient is negative.
How do you tell if a car has a negative or positive system?
Post the year, make and model of the vehicle (in new question) and one of us can tell you if it is negative or positive ground.
