Answer:
Na⁺ Cl⁻
Explanation:
Sodium form cation by losing one electron and chlorine form anion by accepting one electron. Both form ionic compound sodium chloride.
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
electrons are arranged in shells around an atom's nucleus. Electrons closest to the nucleus will have the lowest energy.
First, we convert the given amount of energy into joules.
1 kJ = 1000 joules
2.2125 kJ = 2,212.5 Joules
Each kilocalorie contains 4,184 Joules
Kilocalories = 2,212.5 / 4,182
Kilocalories = 0.529
1 kilocalorie = 1000 calories
0.529 kilocalories = 529 calories
274 amu
Explanation:
Atomic weight of Na = 23
Atomic weight of Sio3 = 76
then,
molecular weight of Na2Sio3 = add 23*2 and 76*3
= 46 and 228
= 274 amu
