<h2>
Answer: c
. Alkaline earth metals (Group 2)</h2>
<h3>
Explanation:</h3>
Group 2 metals have 2 electrons in their outer shell. These two electrons are usually found in the s orbital, hence the s².
Answer:
The atomic number equals the charge on the nucleus. It therefore also equals the number of protons in the nucleus and also equals numerically the number of electrons in the neutral atom. The atomic number has the symbol Z.

Answer:
Explanation:
2HCl = H₂ + Cl₂
2 mole 1 mole 1 mole
73 gram HCl = 73 / 36.5 = 2 mole of HCl
2 moles of HCl will produce 1 mole of chlorine gas .
At STP , one mole of chlorine gas has volume equal to 22.4 litre .
The energy is transferred throughout the rest of the metal by the moving electrons. Metals are described as
malleable (can be beaten into sheets) and ductile (can be pulled out into wires). This is because of the ability of the atoms to roll over each other into new positions without breaking the metallic bond.
The answer is 2, liquid to vapor because vaporization is the process of liquids to vapors.
