Among the following, ionic compound is formed between:
The electrovalent compounds are formed by the transfer of electrons from:
An electrovalent bond is formed when a metal atom transfers one or more electrons to a non metal atom and these compounds are called ionic compounds.
Which of the following element has a tendency to gain electrons?
What are the ions present in NaCl?
The ions present in NaCl is one ion of Na and one ion of Cl. So, option ( c) is the correct one.
The electronic configuration of Phosphorus (atomic number 15) will be:
We know phosphorus has atomic no. 15. Therefore it's electronic configuration is :- 2,8,5 , which means 2 electrons in k- shell, 8 electrons in L-shell and 5 electrons in M - shell.
Due to the presence of strong electrostatic forces of attraction between ions, ionic compounds:
Ionic compounds have high boiling and melting points as they're very strong and require a lot of energy to break.
The valency of magnesium and chlorine in magnesium chloride is:
Magnesium has electronic configuration 2,8,2 . It loses 2 electrons to complete octet configuration in its valence shell. Chlorine has electronic configuration 2,8,7 . It gains 1 electron to complete octet configuration in its valence shell.
Ionic bond involves:
The compounds formed when metals react with non-metals are:
The correct electronic configuration for sodium ion is:
Atomic number of sodium is 11 so its electronic configuration will be 2, 8, 1. But sodium ion is formed by the loss of an electron so its electronic configuration is 2, 8.
Ionic compounds are soluble in water but insoluble in kerosene because:
Water is a polar covalent compound. It decreases the electrostatic forces of attraction,resulting in free ions in aqueous solution. Hence ionic compounds disslove in water. Kerosene is a non polar organic solvent and dissolves non polar covalent compounds.
Valency of aluminium is:
A solution of ionic compound conducts electricity due to the presence of:
Potassium chloride conducts electricity in _______ state.
Potassium Chloride is an excellent water soluble crystalline Potassium source for uses compatible with chlorides.. Chloride compounds can conduct electricity when fused or dissolved in water. Chloride materials can be decomposed by electrolysis to chlorine gas and the metal.
Which of the following will not conduct electricity?
Solid NaCl does not conduct electricity due to absence of free ions.
