Studdy Solution
STEP 1
What is this asking? We need to figure out the chemical formulas and names for the ions of nitrogen and beryllium. Watch out! Don't mix up the charges of the ions with the number of atoms in a molecule!
STEP 2
1. Find Nitrogen's Info
2. Name Nitrogen's Ion
3. Find Beryllium's Info
4. Name Beryllium's Ion
STEP 3
Alright, let's **start** with nitrogen!
Nitrogen wants to gain **three** electrons to have a full outer shell, just like the noble gas neon.
STEP 4
So, when nitrogen gains those **three** electrons, it gets a charge of **negative three**.
STEP 5
That means the chemical formula for a nitrogen ion is .
STEP 6
When a *non-metal* like nitrogen forms a *negative ion*, we change the ending of its name to "-ide".
STEP 7
So, the name of the nitrogen ion is **nitride**.
STEP 8
Now, let's move on to beryllium!
Beryllium is in group 2, so it wants to *lose* **two** electrons to have a full outer shell, just like the noble gas helium.
STEP 9
When beryllium loses those **two** electrons, it gets a charge of **positive two**.
STEP 10
Therefore, the chemical formula for a beryllium ion is .
STEP 11
When a *metal* like beryllium forms a *positive ion*, we just use the element's name.
STEP 12
So, the name of the beryllium ion is simply **beryllium ion**.
STEP 13
1. Chemical formula for nitrogen ion: .
Name: nitride.
2. Chemical formula for beryllium ion: .
Name: beryllium ion.
