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...
Answer 1-4 (#3 and #4 are tables)
shell provides stability to the atom. Different chemical bonds are based on the way in which the atoms fill their valence shells. The major types of chemical bonds include: ionic bonds covalent bonds (both types, i.c. polar covalent and non-polar covalent bonds), and hydrogen bonds. Atoms can use two strategies to fill their valence shell: they can share electrons between their valence shells, or they can give or take electrons from other nearby...
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...
could I get some help answering these questions please? Ive also
provided an info sheet thank you!

9 Name IONIC and COVALENT BONDING LAB ACTIVITY, PROCEDURE and REPORT SHEET BIG IDEAS: ectron configurations determine how atoms combine to form chemical bonds. 2. According to the valence bond theory, the outermost electrons of atoms, the valence electrons, are the ones involved in bonding. 3. Atoms of elements can LOSE, GAIN, or SHARE electrons so that each atom involved achieves a noble gas electron configuration. This is known as the OCTET RULE 4. When atoms lose or gain electrons,...

can
I get some help with determining the formal charges please. and
maybe just look everything over to confirm its correct? thank you!
added an info sheet as well incase that helps

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 these measurements generally...
