That is called an lonic bond.
Ionic bonds are formed
between elements with greater than 1.4 electronegative variance and to a
lesser extent by first ionization energy variance, such as alkali
metals and nonmetal halogens for example. The element of lesser
electronegativity, the cation, donates an electron(s) from it's valance
shell to the element with the greater electronegativity, the anion,
which accepts the electron(s) unto it's valance shell. This bond is
extremely strong and has a high melting point but because of waters
polar nature this type of bond, usually, not always, disassociates in
water.
Answer:

Answer:
Yes, The overall cost of wiring in addressable fire alarm system is significantly cheaper than the conventional one.But the addressale fire alram system is more reliable than a conventional system.
Explanation:
Conventional systems are hardware-based and use analog technology. where addressable fire alarm use digital technology. addressable system is generally more reliable than a conventional system mainly due to how the different systems are wired. With a conventional system, if a device’s wire is damaged or severed, its signal and the signal of other devices down the line cannot be transmitted to the control panel.
With an addressable system, both ends of the wire connect to the control panel. Therefore, if one end becomes damaged or severed, signals can still reach the control panel through the other end of the loop. In addressable systems, a device can be removed or disabled and it will not affect the other devices in the loop.
