Answer:
6
Explanation:
The atomic number for phosphorous is 15, meaning that it has 15 electrons (and protons). The first and second shells would be filled up with 2 and 8 electrons respectively, leaving 5 which goes on the third shell, which is also the valence shell, meaning phosphorous has 5 valence electrons.
Since the atomic number of sulfur is 16, the first and second shells are also filled up with 2 and 8 electrons respectively, leaving 6 to be on the third shell, the valence shell. Hence, sulfur has 6 valence electrons.
12% NaCl is the answer I came to... Have a GREAT day!!! :)
I think it’s A sorry if i’m wrong
Sodium (Na) and Argon (Ar) on the periodic table does not have similar properties.
PERIODIC TABLE:
- Periodic table is the organized table that showcases the position of elements. The periodic table is organized into groups and periods.
- Groups of the periodic table is in a vertical format labeled 1 - 7 while the period is in a horizontal format labeled 1 - 7.
- Elements in the same group have the same number of valence electrons and hence, possess similar chemical properties.
- Sodium (Na) belongs to group 1 while argon is a noble gas, hence, they are not in the same group of the periodic table and cannot have same properties.
