Chlorine
Sodium is indeed a period 3 element in the periodic table. It is classified as an alkali metal and is highly reactive due to its tendency to lose its outermost electron easily.
The element with 10 more protons than sulfur is argon. Sulfur has 16 protons, while argon has 18 protons.
Noble gasses are least reactive of all the elements. So the least reactive element in the period 4 is Krypton. It is a noble gas with an atomic number of 36.
Yes you are correct, potassium being an alkali metal is definitely more reactive than argon which is a noble gas (group 18 element). Potassium reacts violently with just water while argon is very inert and stable, which is why it remains in the atmosphere as a monatomic element.
Period six on the periodic table starts the row after Xenon. The electron shell 6s2 6p2 corresponds to the atomic number 82. This is lead.
No, chlorine is in the same period as argon but not sulfur. Chlorine and argon are both in period 3 on the periodic table, whereas sulfur is in period 3 of the periodic table.
Sulfur and argon do not have similar chemical properties. Sulfur is a reactive nonmetal that readily forms compounds, while argon is an inert gas that is very stable and does not easily react with other elements. Argon is a noble gas with a full outer electron shell, while sulfur is a nonmetal that can gain electrons to achieve a stable configuration.
The elements in group 15 period 3 are phosphorus, sulfur, chlorine, argon.
Sodium is indeed a period 3 element in the periodic table. It is classified as an alkali metal and is highly reactive due to its tendency to lose its outermost electron easily.
Argon is a period 3 element.
No, argon is not more reactive than oxygen. In fact, argon is a noble gas and is very non-reactive, while oxygen is a highly reactive element that readily participates in chemical reactions.
The element with 10 more protons than sulfur is argon. Sulfur has 16 protons, while argon has 18 protons.
Argon is a Non-Reactive Element. Magnesium is a very Reactive Element. Magnesium will react violently when ignited in an Oxygen rich environment.
Argon is the gas among these. Other elements are solids.
This tells us that argon has a full outer electron shell, making it stable and unreactive. Elements at the end of a period often have filled electron shells, giving them properties different from other elements in the same period.
The element in group 16 with more protons than sodium but fewer protons than argon is sulfur (S). Sodium has 11 protons, sulfur has 16 protons, and argon has 18 protons.
It is a period 3 element.
