Which pair will for an ionic compound

vovikov84 [41]

Answer: A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.

Explanation:

A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.

Explanation:

The chart below shows monatomic ions formed when an atom loses or gains one or more electrons, and the ionic compounds they form. You can check your periodic table to see that the cations are monatomic ions formed from metals, and the anions are monatomic ions formed from nonmetals.

What is the molecular formula of an empirical N2H3 if n=2? <br><br>SHOW WORK!

aliya0001 [1]

A compound's empirical formula tells you what the smallest whole number ratio between the atoms that make up that compound is.

I think of the empirical formula as a building block for molecules. A compound's molecular formula will depend on how many building blocks are needed to build a molecule of a given substance.

In your example, you know that the empirical formula of the compound is

This tells you that the minimum ratio between nitrogen atoms and oxygen atoms is

. In other words, the molecular formula will be a multiple of this building block.

molecular formula

empirical formula

, where

- the number of building blocks needed to build the molecular formula.

You also know that the molar mass of your compound is

92 g/mol

This means that the molar mass of all the atoms that make up that molecule must add up to give

92 g/mol

So, how would you determine how many building blocks you need? Well, start by figuring out the molar mass of one building block, i.e. the molar mass of the empirical formula.

Since it contains one nitrogen atom and two oxygen atoms, you will get

14.0067 g/mol

15.9994 g/mol

46.0055 g/mol

So, if one building block has a molar mass of

46.0055 g/mol

, how many would you need to get the molecule?

46.0055 g/mol

⋅

92 g/mol

This means that the compound's molecular formula, which lists all the atoms that make up a molecule, will be

Why does electronegativity increase as you move from left to right across

Katen [24]

Answer: increasing number of protons increases the positive charge of the nucleus.

Explanation: because as the electronegativity moves from left to right on the periodic table the protons do increase to make it into a positive charge.
