Answer:
Option B. Sodium
Explanation:
In the formation of NaCl, sodium loses and electron while chlorine receives the electron as illustrated below:
Na —> Na+ + e- ....... (1)
Cl + e- —> Cl- ......... (2)
Now, combining equation 1 and 2 we have:
Na + Cl + e- —> Na+ + Cl- + e-
Cancelling the electron from both side, we obtained:
Na + Cl —> Na+Cl-
From the above illustration, we see clearly that sodium loses electron
Answer: metals, 88 , periodic table , luster , heat, electricity , thin, right, opposite , appearance , luster , malleable , ductile, opposite , shiny, moderately
Explanation:
Most of the elements in the periodic table are metals. Most of them are present on the left side of the periodic table. Elements to the far right of the periodic table are nonmetals. Elements which exhibit properties of both metals and nonmetals and are termed metalloids or semimetals.
Metals are defined as the elements which loose electrons to attain stable electronic configuration. They are hard ,malleable ( betaen to sheets) ,ductile ( drawn into wires) ,sonorous ( produce sound ) etc.
Non-metals are defined as the elements which gain electrons to attain stable electronic configuration. They are brittle and soft and are the poor conductors of heat and electricity.
Metalloids are defined as the elements which show properties of both metals and non-metals. Metalloids are typically semi-conductors, which means that they both insulate and conduct electricity.
