Are valence electrons positive or negative?
carbon is a negatively and positively charged ion since it can gain or lose 4
Compare and contrast the possession of electrons in ionic and covalent bonds?
In an ionic bond, one atom loses electrons( becomes more positive) and the other gains the electrons ( becomes more negative) what keeps them bonded is the now positive/negative attraction. In covalent bonding, both atoms share the electrons, but are again held together by positive/negative attraction.
Is NO nonpolar covalent or polar covalent?
NO is polar. If you compare the electronegativities (how strongly the element pulls on electrons) N 3.04 O 3.44 ( bigger therefore pulls electrons harder) The electrons will be drawn to the oxygen causing it to be slightly negative, and the N to be slightly positive.
Why are most molecular compound poor conductors?
Molecular compounds are poor conductors because they have no charge. Molecular compounds are simply just covalent bonds. Since covalent compounds dont give or take, they SHARE valence electrons they have no charge. Electricity is only created by positive and negative electrons, but since a molecular compound has no charge they are poor conductors. ONLY MOST ARE POOR CONDUCTORS. Why? Sometimes there is an unbalance and some molecules like Water tend be favor positive or negative, water for instance is just slightly negative.
Is the attraction between a positive ion and a negative ion in a covalent bond true or false?
False. A covalent bond is formed by the sharing of valence electrons.
Does a covalent compound have balanced negative and positive charges?
Yes
Are valence electrons positive or negative?
carbon is a negatively and positively charged ion since it can gain or lose 4
Is an ionic compound polarcompound?
Yes. We have covalent polar bonds, covalent not polar bonds and ionic bonds. If the electronegativity is below 1.2, the bond is covalent and not polar and the compound shares electrons..If EN is between 1.2 and 1.8 the bond is covalent polar which means that electrons are still shared, but one compound is more dominant and pulls the electrons stronger than the other. When the electronegativity is 1.8 or more, one compound takes away an electron and becomes negativ, and the other compound looses the electron and becomes positive. Positive and negative items attract each other and that is a polar bond.

In an ionic bond, one atom loses electrons( becomes more positive) and the other gains the electrons ( becomes more negative) what keeps them bonded is the now positive/negative attraction. In covalent bonding, both atoms share the electrons, but are again held together by positive/negative attraction. Short version: In ionic bond, one element in an ionic bond loses electrons, while the other gains electrons. Electrons are shared equally in covalent bonds.
what is polar covalent compounds?
A polar covalent compound is a compound consisting of molecules which have regions of positive and negative charge due to the covalent bonding between atoms. The atom with a greater charged nucleus ( atoms with greater proton number) will attract the shared electrons causing them to move closer to the nucleus which will make this slightly negatively charged due to the negative electrons. The atom which the shared electrons has moved away from ( atoms with smaller proton number) will become slightly positively charged.
Is nitrogen trifluoride a covalent bond?
Covalent because it has Tri as a prefix and it shares electrons.
Is NO nonpolar covalent or polar covalent?
NO is polar. If you compare the electronegativities (how strongly the element pulls on electrons) N 3.04 O 3.44 ( bigger therefore pulls electrons harder) The electrons will be drawn to the oxygen causing it to be slightly negative, and the N to be slightly positive.
When a compound donates electrons the compound becomes what?
if a neutral atom donates an electron it will gain a positive charge. This is due to electrons having a negative charge.
Why are most molecular compound poor conductors?
Molecular compounds are poor conductors because they have no charge. Molecular compounds are simply just covalent bonds. Since covalent compounds dont give or take, they SHARE valence electrons they have no charge. Electricity is only created by positive and negative electrons, but since a molecular compound has no charge they are poor conductors. ONLY MOST ARE POOR CONDUCTORS. Why? Sometimes there is an unbalance and some molecules like Water tend be favor positive or negative, water for instance is just slightly negative.
Why some time covalent compounds are called poler covalent compound?
Polar covalent compounds: unequal sharing of electrons. Basically, one element has a much higher electronegativity ("liking" of electrons) than the others. Like in water: Oxygen has a much higher electronegativity and positive charge than the hydrogens. So, the electrons will spend most of their time with the oxygen. This will make the oxygen act like a negative and the hydrogen act like a positive.
Is the attraction between a positive ion and a negative ion in a covalent bond true or false?
False. A covalent bond is formed by the sharing of valence electrons.
