In these atoms, the positive and negative charges cancel each other out, leading to an atom with no net charge.
(Protons, neutrons, and electrons)
Exothermic is when heat escapes an object. So the answer should be the last one.
Answer:
2
Explanation:
The number of carbon atoms that are sp²-hybridized in this alkene is 2
Because all the single bonded carbon atoms in the alkene are sp²-hybridized
There are three(3) single formed via sp² orbitals and one ( 1 ) PI bond formed via Pure-P-orbital
attached below is the some part of the solution
Answer:
More electronegative element in each pair
O & F ⇒ Fluorine is more electronegative.
O & Br ⇒ Oxygen is more electronegative.
O & S ⇒ Oxygen is more electronegative
O & N ⇒ Oxygen is more electronegative
O & P ⇒ Oxygen is more electronegative
O & K ⇒ Oxygen is more electronegative
O & Ca ⇒ Oxygen is more electronegative
Explanation:
Electronegativity is the measure pf tendency to attract bond pair electrons towards itself in a covalent bond.
More electronegative element attract bond pair electron from less electronegative element.
Electronegativity increases along the peroid when we move from left to right in perodic table and decreses down the group or top to bottom in periodic table.
So Oxygen, Fluorine, Chlorine and Nitrogen are the most electronegative among the all elements in periodic table.
