Question

neutral atoms.
1. Oxygen (O)
2. Aluminium (Al)
3. Neon (Ne)
4. Silicion (Si)
5. Magnesium (Mg)
6. Iodine (I)
7. Lithium (Li)
8. Nitrogen (N)
number of valence electrons present
a.8 valence electrons
b.4 valence electrons
c.3 valence electrons
d.1 valence electrons
e.2 valence electrons
f.5 valence electrons
g.6 valence electrons
h.7 valence electrons

Answer 1

To determine the number of valence electrons for each of the specified neutral atoms, we can refer to their positions on the periodic table. Here is the breakdown for each atom:

1. Oxygen (O): 6 valence electrons (g)
2. Aluminium (Al): 3 valence electrons (c)
3. Neon (Ne): 8 valence electrons (a)
4. Silicon (Si): 4 valence electrons (b)
5. Magnesium (Mg): 2 valence electrons (e)
6. Iodine (I): 7 valence electrons (h)
7. Lithium (Li): 1 valence electron (d)
8. Nitrogen (N): 5 valence electrons (f)

So, summarizing the number of valence electrons for each atom:

• Oxygen (O): 6 (g)
• Aluminium (Al): 3 (c)
• Neon (Ne): 8 (a)
• Silicon (Si): 4 (b)
• Magnesium (Mg): 2 (e)
• Iodine (I): 7 (h)
• Lithium (Li): 1 (d)
• Nitrogen (N): 5 (f)
