What is the difference between ionic and covalent compounds?
k0ka [10]
<h3><u>Answer;</u></h3>

D. All the above

  • Covalent compounds are always poor conductors of electricity while ionic compounds conduct electricity well when melted or dissolved.
  • Covalent compounds can be solid, liquid or gas, but ionic compounds are solids.
  • In covalent compounds the elements present are usually close together on the periodic table whereas in ionic compounds they are usually well separated.
<h3><u>Explanation;</u></h3>
  • <u>Ionic compounds are compounds that are formed from strong electrostatic interactions between ions.</u> Ionic bonding occurs between a nonmetal, which acts as an electron acceptor, and a metal, which acts as an electron donor. The atoms involved in ionic bonding lose or gain electrons and form positively or negatively charged ions.
  • <em><u>Ionic compound are good conductors of electricity both in molten and aqueous form,. while covalent compound are poor conductors of electricity.</u></em>
  • <u>Covalent compounds on the other hand are compounds that have bonds where electrons are shared between atoms.</u> These types bonds mostly occur between nonmetals or between two atoms of the same element.

The atomic mass of titanium is 47.88 atomic mass units. This atomic mass represents the
kkurt [141]
Answer (3) is the most correct, although (2) is not to be ignored. (3) states the most abundant isotope Ti's average mass, which is certainly true. (2) is the total mass of all protons, neutrons, and electrons in an atom of Ti, which is true but has to be more specific in order to pinpoint exactly the 47.88 amu. (4) is incorrect because it is not of all the naturally occurring isotopes of Ti. (1) is incorrect because they forgot electrons.

What is the expected mass (in kg) of a 10 over 5 B isotope? 1 proton = 1.6726 × 10-27 kg 1 neutron = 1.6749 × 10-27 kg A.1.67 ×
Ira Lisetskai [31]
^{10}_5 B
An atom of this isotope contains 5 protons and 10-5=5 neutrons.

5 \times 1.6726 \times 10^{-27} + 5 \times 1.6749 \times 10^{-27} = \\&#10;8.363 \times 10^{-27} + 8.3745 \times 10^{-27}= \\&#10;16.7375 \times 10^{-27}= \\&#10;1.67375 \times 10^{-26} \approx \\&#10;1.67 \times 10^{-26}

The answer is A. 1.67 × 10⁻²⁶ kg.
