(a) it was formed when electrons were shared
NaCl is an ionic bond which means an electron(s) was transferred (from one atom to another to make them stable) not a covalent bond which means an electron(s) was shared
You can extract the iron fillings from the sand by using a magnet
Answer:
The charge of nucleus will be +2.
Explanation:
Given that,
Proton = 16
Neutron = 14
electron = 18
We know that,
Atomic number :
The number of proton in the nucleus is equal to the atomic number.
The number of protons is equal to the number of electrons for neutral atom.
So, the atomic number is same as the number of electrons.
Here, the number of electron is more than 2 of number of proton.
Hence, The charge of nucleus will be +2.
