What else can I help you with?
Is sodium metal?
Sodium metal is a highly reactive element with a silvery appearance. It is soft enough to be cut with a knife and must be stored in a damp-free environment to prevent rapid oxidation. Sodium is commonly found in compounds like table salt (sodium chloride).
What is he element is found in the same period as sulfur and argon and that is more reactive than sulfur and argon?
The element found in the same period as sulfur and argon, and more reactive than both, is chlorine. Chlorine is a highly reactive nonmetal that belongs to the same period (or row) as sulfur and argon on the periodic table.
What is The halogen in the third period?
The halogen in the third period is chlorine (Cl). It is a highly reactive non-metal element that is part of Group 17 in the periodic table. Chlorine is commonly used for disinfection purposes and in the production of various chemicals.
Which element is the least reactive in period 4?
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.
The atomic number of sodium the first element in Period 3 is 11 The atomic number of the second element in this period is?
The second element in Period 3 is Magnesium, with an atomic number of 12.
What element is in group 1 period 3?
The element in group 1 period 3 is sodium. Sodium has an atomic number of 11 and is a highly reactive metal.
What element is NaI?
Yes,Na represents an element. It is the symbol for sodium.Its atomic number is 11.Na stands for sodium. It locates in the 3rd period because it has electrons in three different energy levels. It is an alkali metal as it has only one electron in outermost shell.Yes, Na is an element in the 1st group. It is an alkaline metal. It is highly reactive.

The element found in the same period as sulfur and argon, and more reactive than both, is chlorine. Chlorine is a highly reactive nonmetal that belongs to the same period (or row) as sulfur and argon on the periodic table.
Two highly reactive elements in period 2 are the metal lithium and what?
The other highly reactive element in period 2 is fluorine, a non-metal. Both lithium and fluorine readily form compounds due to their high reactivity.
What is the 11th element of the periodic table?
The 11th element of the periodic table is Sodium (Na), which has an atomic number of 11. Sodium is a soft, silvery-white, highly reactive metal that is commonly found in table salt and various minerals.
What element is very reactive has properties similar to those of magnesium and is in the same period as bromine?
The element that fits this description is chlorine, which is a highly reactive halogen with properties similar to those of magnesium. Chlorine is located in the same period as bromine (Group 17, Period 4) in the periodic table.
In period 5 which is a halogen?
Period 5 of the periodic table includes the halogen element bromine (Br). It is a highly reactive nonmetal and exists as a diatomic molecule in its natural state.
As you go down a period does the element become more reactive or less reactive when placed in water?
more reactive
What is the characteristic of last element in each period of periodic table?
The last element in each period is a noble element. It is non-reactive.
What element is group 1 period 3?
Third period has 8 elements. They have 3 electron shells.
How does reactivity change from an element in group 1 to an element in the same period in group 2?
Reactivity decreases from group 1 to group 2 within the same period. Group 1 elements, like lithium and sodium, are highly reactive due to their single valence electron, which they readily lose to form positive ions. In contrast, group 2 elements, such as magnesium and calcium, have two valence electrons, making them less reactive since they require more energy to lose both electrons. Consequently, while both groups are reactive, group 1 elements are generally more reactive than their group 2 counterparts in the same period.
