Answer:
1s2 2s2 2p6
Explanation:
The nitride ion(N^3-) is formed when nitrogen gains three electrons. Nitrogen possesses seven electrons in its orbitals and ordinarily has the electronic configuration; 1s2 2s2 2p3. However,being in group 15, nitrogen can accept three electrons to form the nitride ion and complete its octet of electrons. When this happens, three electrons are added to the nitrogen atom and the electronic configuration is now the same as that of Neon, its closest noble gas which is 1s2 2s2 2p6. Hence the answer given above.
Elements can accept or donate electrons in order to complete their octet structure in accordance to the octet rule which states that atoms and ions must possess eight electrons in their outermost shell in order to attain chemical stability. The reason for ion formation and chemical reaction is in order for species to attain the octet structure.
An element is <span>a part or aspect of something abstract, especially one that is essential or characteristic. I hope this helps you good luck :)</span>
Answer:
Chlorine has seven valence electrons
Explanation:
The dot structure of chlorine was just described in the question. The two dots above, below and by the left are three lone pairs making a total of six electrons. There is another one black dot indicating one electron.
This one electron on both chlorine atoms combine to form the chlorine molecule Cl2.
Answer:
NH4
Explanation:
empirical formula is the ratio of all elements to each other. so
2:6= 1:4
that's why
N1H4 or NH4
