3. The number of electrons and neutrons in an atom are 13 and 14, respectively. Find out the mass number, atomic number, valency
QveST [7]

Answer:

Explanation:

3. The number of electrons and neutrons in an atom are 13 and 14, respectively. Find out the mass number, atomic number, valency, and symbol of the element.

For a neutral atom. number of protons =number of electrons=13

so since atomic number is the number of protons =13

mass number = protons + neutons =14+13 = 27

atomic number 13 is Aluminum (AL-(see periodic table)

The electronic structure for 13 electrons is 1s2s2p63s23p1

so Al has 3 electrons which are VALIENT and can react and when it loses the 3 it will have  CHARGE OF +3

The. bond dissociation enthalpies of the H-H bond and the H-Cl bond are 435 kJ mol^-1 and 431 kJ mol^-1, respectively. The ΔHfO
Novay_Z [31]

The bond dissociation energy of the Cl - Cl bond is -958 kJ mol^-1.

<h3>What is the dissociation enthalpy?</h3>

Given that;

H-H bond energy =  435 kJ mol^-1

H-Cl bond energy = 431 kJ mol^-1

ΔHfO of HCL(g) = -92kJ mol^-1

Bond dissociation enthalpy of the Cl-Cl bond = x

-92 = 435  +  431 + x

x = -92 - (435  +  431)

x = -958 kJ mol^-1
