Question

2. Which of the following elements lose electrons when react with each other potassium and iodine, sulfur and sodium, magnesium and oxygen, fluorine and lithium. Көмекккк​

Answer 1

2K + I2= 2KI
K^0-e=K^+1 oxidation
I2^0+2e=2I^-1 reduction
Potassium loses 1 electron
S+2Na=Na2S
S^0+2e=S^-2 reduction
Na^0-e=Na^+1 oxidation
Sodium also loses 1 electron
2Mg+O2=2MgO
Mg^0-2e=Mg^+2 oxidation
O2^0+4e=2O^-2 reduction
Magnesium loses 2 electrons
F2+2Li=2LiF
F2^0+2e=2F^-1 reduction
Li^0-e=Li^+1 oxidation
Lithium loses 1 electron

Answer: K, Na, Mg, and Li

Answer 2

When elements react with each other, they typically either gain or lose electrons to achieve a stable electron configuration. Elements on the left side of the periodic table, such as alkali metals, tend to lose electrons to form positive ions (cations), while elements on the right side of the periodic table, such as halogens, tend to gain electrons to form negative ions (anions).

Let's look at the pairs of elements you mentioned:

1. Potassium (K) and Iodine (I): Potassium is an alkali metal, and it tends to lose electrons to form K+ ions. Iodine is a halogen, and it tends to gain electrons to form I- ions. So, in this pair, potassium loses electrons, and iodine gains electrons.

2. Sulfur (S) and Sodium (Na): Sulfur is a non-metal and can gain electrons to form S2- ions, while sodium is an alkali metal and tends to lose electrons to form Na+ ions. So, in this pair, sulfur gains electrons, and sodium loses electrons.

3. Magnesium (Mg) and Oxygen (O): Magnesium is an alkaline earth metal and tends to lose electrons to form Mg2+ ions. Oxygen is a non-metal and can gain electrons to form O2- ions. So, in this pair, magnesium loses electrons, and oxygen gains electrons.

4. Fluorine (F) and Lithium (Li): Fluorine is a halogen and tends to gain electrons to form F- ions. Lithium is an alkali metal and tends to lose electrons to form Li+ ions. So, in this pair, lithium loses electrons, and fluorine gains electrons.

So, to answer your question, the elements that lose electrons when they react with each other in the provided pairs are:

• Potassium (K) when reacting with Iodine (I).
• Sodium (Na) when reacting with Sulfur (S).
• Magnesium (Mg) when reacting with Oxygen (O).
• Lithium (Li) when reacting with Fluorine (F).
