Which element is Sonya most likely studying?
nonmetal element
Which element is Sonya most likely studying sulfur’s Neon NE fluorine F iodine?
Answer is: fluorine (F).
What best describes the states of nonmetals when they are at room temperature?
What best describes the states of nonmetals when they are at room temperature? Most nonmetals are gaseous, but some are liquid or solid.
Which element is likely more reactive and why element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table element 1 is more reactive because it has more electrons in its valence shell and is farther to the right?
Which element is likely more reactive, and why? Element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. Element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table.
What is the most reactive element in Group VI?
Cesium
What makes an element more reactive?
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Alkali metals are highly reactive because they readily lose the single electron in their outermost shell.
Why does Group 7 get less reactive?
Reactivity decreases down the group. This is because group 7 elements react by gaining an electron. As you move down the group, the amount of electron shielding increases, meaning that the electron is less attracted to the nucleus.
Why is Group 7 more reactive as you go up?
The group 7 elements want to gain one more electron so that they have a stable electronic structure. The smaller the atom, the easier it is to grab an electron from another atom, making the atom more reactive. As you go down group 7, the atomic radius increases and it becomes more difficult to attract another electron.
What is another name for Group 0 elements?
The elements in group 0 are called the noble gases . They exist as single atoms .
Which metal reacts with the most solutions?
The primary difference between metals is the ease with which they undergo chemical reactions. The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.
Which element in each pair is more reactive?
Answer: (1) O is more reactive.
Is magnesium stored in kerosene?
C.) Magnesium. The metal higher in reactive series reacts with the Oxygen, Carbon dioxide (CO2) and moisture present in the air and may cause fire. In order to prevent these metals from accidental fire, they are kept immersed in kerosene.
Why is sodium and potassium are stored in kerosene?
Na and K are very reactive metals and kept in kerosene oil to prevent it from coming in contact with oxygen and moisture as they react to form their hydroxides. This is an exothermic reaction and lot of heat is generated so both the metals are kept in kerosene oil.
Is Cobalt more reactive than zinc?
For example, magnesium metal can displace zinc ions in a solution. Mg(s) + Zn2+ →→ Zn(s) + Mg….Reactivity Series of metals Chart.
| Metal | Cobalt |
|---|---|
| Symbol | Co |
| Reactivity | Displaces H2 gas from acids only and forms hydroxides. |
| Extraction | Smelting with coke |
Is Zinc highly reactive?
Zinc is a lustrous bluish-white metal. It is a fairly reactive metal that will combine with oxygen and other non-metals, and will react with dilute acids to release hydrogen.
