Answer: B
Mg after losing 2 electrons attains noble gas configuration. So
removing 3rd electron from already stable noble gas configuration
requires huge lot of energy

Answer: A
This is definition of ionic bond

Part A Review Constants Periodic Table Learning Goal: Consider the following element combinations. Classify the bonds formed between each pair as ionic, polar covalent, or nonpolar covalent qualitatively based solely on each element's position on the periodic table. To use electronegativity or metal versus nonmetal classifications to distinguish covalent polar covalent, and ionic bonds. not conduct calculations. Drag the appropriate items to their respective bins. When two bonded atoms attract electrons with View Available Hint(s) equal strength, the result is...
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
Answer true or false. 1. Atoms that lose electrons to achieve a filled valence shell become cations and form ionic bonds with anions. 2. Ionic bonds tend to form between elements on the left side of the Periodic Table, and covalent bonds tend to form between elements on the right side of the Periodic Table. 3. Electronegativity is a measure of an atom's attraction for the electrons it shares in a chemical bond with another atom. 4. Fluorine, in the...
Pre-Lab Exercise 2-3 Chemical Bonding One of the more challenging concepts to grasp in chemistry is chemical bonding, a topic that pops up again and again in A&P: We revisit it in cytology, the nervous system, blood, respiration, and digestion-to name just a few First let's do some basics. Use your textbook and this unit to answer the following questions 1. Do metals donate or accept electrons? What do they become after they donate/accept electrons? 2. Do nonmetals donate or...

Х Lab 11.pdf Lab 11.pdf INTRODUCTION The chemical and physical properties of substances are influenced by the way in which valence electrons are distributed and by the three-dimensional shape of the molecule or ion. X- ray and neutron diffraction, infrared, Raman and microwave absorption spectroscopy, as well as dipole moment measurements, are used to ascertain the three-dimensional structure of a substance. Thus, techniques are available which can identify the geometry of substances Results of...
