Why are the valence electrons of an atom the only electrons likely to be involved in bonding to other atoms?
It is because only certain (the outer) electrons are available for chemical bonding that they are called valence electrons. By definition, the electrons available for bonding are called valence electrons. The others are more tightly bound to the nucleus.
Valence electrons are responsible for the makeup of the chemical properties of elements?
they are responsible for eletronegativity, ionic/covalent bonding, and it's basic properties ie: melting point for metals
Why is the outer shell of electrons thought to be the most important for determining chemical properties?
since the inner shells are filled, it is the outer electrons that take part in the bonding. They can give away 1 or 2 or 3 electrons or take 1 or 2 or 3 to fill their outer ring. Or they can share.electrons in the outer ring.
Which statement is most likely to be true of the chemical species that donates electrons to a coordinate covalent bond?
It has a lone pair of valence electrons.
Is it true that Lewis dot structure shows only valence electrons?
Because they are the only ones involved in bonding. For example, when an forming an ionic compound one atom loses its valence electrons and one gains electrons to make its valence electron shell complete.

Are convalent bonds formed from sharing of valence electrons?
Covalent bonding.
Is it true atoms with fewer than 4 valence electrons tend to gain electrons when bonding?
No! Atoms with more than 4 electrons gain electrons during bonding. Atoms with less than 4 electrons tend to lose electrons during bonding. Hope this helps!
Which statement is most likely to be true of the chemical species that donates electrons to a coordinate covalent bond?
It has a lone pair of valence electrons.
Is it true that to find the total number of electrons available for bonding in a positive ion you should add the ion charge to the total number of valence electrons of the atoms present?
yes
Is it true that Lewis dot structure shows only valence electrons?
Because they are the only ones involved in bonding. For example, when an forming an ionic compound one atom loses its valence electrons and one gains electrons to make its valence electron shell complete.
What happens to the valence electrons of the atom during bonding?
=When an atom forms a chemical bond, one of two things usually happens to the valence electrons. Either the number of valence electrons increase to a total of eight (the most valence electrons that an atom can have), or all the valence electrons are given up.==When atoms end up with eight or zero valence electrons, the atom becomes more stable-or less reactive- than it was before.=
Valence electrons are the electrons found on the last shell of an atom true or fase?
True
Is it easier to lose electrons when the valence electrons are far from the nucleus?
Yes, it is true.
Which of the following statements are true about whether atoms tend to gain or lose electrons?
Atoms with eight valence electrons usually do not gain or lose electrons. Atoms with one, two, or three valence electrons will lose electrons.
