<h2>The compound formed is NaCl and $CaCl_{2}$ </h2>

Explanation:

PART 1:

Atomic number of sodium is 11.
Sodium(Na, Z = 11, Group 1A) will lose 1 electron to become $Na^{1+}$ which is isoelectronic to Neon (Ne ,Z = 10).
The symbol for the sodium ion is $Na^{+}$ .
Chlorine atom ( $Cl$ , Z = 17, Group 7A or 17) gains 1 elecron to be isoelectronic to neon.
The symbol for the compound formed is NaCl.
PART 2:
Atomic number of calcium is 20
Calcium(Ca, Z = 20 ,Group 2A) will lose two electrons to become $Ca^{2+}$ which is isoelectronic to argon.
The symbol for the ion is $Ca^{2+}.$
Two chlorine atoms (Cl, Z = 17, Group 7A or 17) each gains one electron to be isoelectronic to argon(Z = 18)
The symbol for the compound formed is $CaCl_{2}$ .

As electricity flows through a copper wire, the temperature of the wire increases. Some parts of the wire get warmer than others

mezya [45]

Answer:

Conduction

Explanation:

The heat can be transferred in the substances in three ways: conduction, convection, and radiation.

The conduction happens inside the material, usually a solid, and the heat flows as the molecules of the substance are agitated. The convection happens when there are different substances in touch, so it is the heat passage from a solid to a liquid or gas, from a gas to a liquid or vice versa. The radiation occurs between substances that are far away and the heat flows by electromagnetic waves.

Thus, in the wire, the heat flows by conduction.
