In chemistry, yes...yes it is.
Al (1s²2s²2p⁶3s²3p¹) - 3e⁻ → Al³⁺ (1s²2s²2p⁶)
3s²3p¹
Orbital s is always the first one to fill up
Increase temperature = particle move faster
increase Concentration =more crowded so more collisions
Explanation:
when temperature increase,the particle gain kinetic energy which make the particles move faster hence more collisions.
if concentration increase,there will be more frequent collisions between the particles due to crowded
Answer:
6
Explanation:
bromine has 1, hydrogen has 4 and nitrogen has 1 therefore equaling 6
