Each column is called a group<span>. The elements in each </span>group have<span> the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.</span>
Answer:
Ag+
Explanation:
anode: 2AgNO3(l)⟶Ag(aq)+NO3(g)
Answer:
It is due to the nature of the reactants
Explanation:
To ignite a solid, we require more heat component compared to liquids and gases. For ignition to occur, oxygen gas combines with a reactant in most cases.
Some factors affect the rate rate at which a chemical proceeds. One of the factors is the nature of reactants.
The solid phase is very slow while the gaseous phase is rapid and fast.
solid phase < liquid phase < gas phase
Gases are free and the molecules move in all direction. They easily combine and react very fast.
- No of protons=No of electrons=15
<h3>Mass no:-No of neutrons+No of protons </h3>
Now
- It has atomic no 15 hence its Phosphorus(P)
Electronic configuration:-
