Explanation: You're welcome and can you pls give me the brainiest
Answer:
Four
Explanation:
P has five valence electrons. It can form bonds to three other atoms (like H) to form a triangular pyramidal molecule with a lone pair on the P atom.
If P atoms are to form bonds with each other, we can get a stable arrangement by putting each atom at the corner of a tetrahedron.
In a P₄ molecule, each atom still has three bonds and a lone pair.
Answer:
(4) 230 kPa
Explanation:
The temperature is constant, so the only variables are pressure and volume.
We can use Boyle’s Law.
Divide both sides of the equation by 
.
3) Answer is: because elements have different emmision spectrum.
Emission spectrum of a chemical element is the spectrum of frequencies emitted due to an atom making a transition from a high energy state to a lower energy state. Each element's emission spectrum is unique.
4) Answer is: lithium chloride and sodium chloride do not have similar colors.
Lithium ion has red and sodium ion has yellow emission spectrum.
5) Answer is: because metals have valence electrons in different energy shells.
Each transition has a specific energy difference.
6) Answer is: salts of alkaline and earth alkaline metals.
For example barium chloride gives green light.
