Because of the number of valence electrons (determined above], how many electrons will the lose or...
In this text,
valence = (number electrons in valence sheel of free
atom)-(number non-bonding electrons on atom in molecule)
or
valence = (number of bonds)+(formal charge)
figure.4 has two models of CH5+ and text says first model has
valence of 6 which I don't understand.
according to equation above. shouldn't valence be
valence = 4-0=0 or valence=5+1(I'm not sure... because there
are one electron in hydrogen)=6??
how many valence electrons do the following elements have( hint, this is how they appear on the Periodic Chart, before they gain or lose electrons) Br He Mg P He K
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...
How many electrons does potassium need to lose to become an ion? Will it become a positively charged cation or a negatively charged anion? How many electrons must nitrogen gain to become like its closest noble gas, Neon? What are valence electrons?
How many valence electrons does an atom of praseodymium, Pr, have? How many unpaired electrons does an atom of Samarium, Sm, have? What is the geometry for the ClO4- ion? What is the bond angle in the ClO4- ion?
Procedure A. For each compound below: 1. Determine how many valence electrons belong in the Lewis structure for the compound. 2. Draw a Lewis structure in the spaces provided below. Be sure to show the correct number of bonds between atoms and place the correct number of lone pairs on each atom. Remember, hydrogen doesn't get any lone pairs, and all the other atoms like to get an octet. When you are finished, have your instructor check your structures before...

Which of these elements would have the highest number of valence electrons? Phosphorus Beryllium Bromine Sulfur Which of these elements requires the highest amount of energy to remove a valence electron resulting in the formation of a cation? Boron Carbon Oxygen Sodium Atomic radius increases down a group (family) because: There are less and less protons in an atom. There are more and more electrons in an atom and electrons take space. There are less and less electrons in an...
