Answer:
calculate the valency
Step-by-step explanation:
7N14 =3
17Cl35=1
The valency of ¹⁷N₇ and ³⁵Cl₁₇ is -3 and -1 respectively .
In 1916, Gilbert N. Lewis used the tendency of (main-group) atoms to achieve a stable octet of 8 valence-shell electrons to explain valence and chemical bonding.
When two atoms of one element unite with one atom of another to form a molecule, this combination is known as valency. Valency and molecular weight are two related terms. A measure of an atom's combining capability is its valency. The quantity of electrons in an element's outermost shell determines its valency. Electronic setup can be used to assess the valency of 17N7.
¹⁷N₇ has an electrical configuration of 2,5.
For it to complete an octet, it requires three additional electrons.
The charge will be -ve because it will gain 3 electrons to achieve a noble gas electrical configuration.
The ¹⁷N₇ valency will be -3.
Similar to this, ³⁵Cl₁₇ has an electrical arrangement of 2,8,7.
It needs one more electron to round out its octet.
It will pick up an electron, making the charge negative.
The valency of ³⁵Cl₁₇ is negative.
