What else can I help you with?
Is PBr3 a molecular compound?
No. Since BH3 lacks a lone pair it would be a Lewis acid.
What is the substance of classified as compound?
A compound is defined as a substance that contains at least two chemical elements and always has a constant mass ratio between elements for each possible pair of the elements that are present in it.
Is Cl2 an element or a compound?
ClO4 is not a compound, it exists as ClO4-, which is a polyatomic ion called the perchlorate ion. Some positive ion such as potassium or ammonium must be present to balance the charge and form a compound.
What is the molecular geometry of nitrogen tribromide?
The molecular geometry of nitrogen tribromide (NBr3) is trigonal pyramidal. Nitrogen has a lone pair of electrons, causing the three bromine atoms to form a trigonal pyramid around the central nitrogen atom.
Is fluorine and iodine a most likely pair to form a ionic compound?
Fluorine and iodine are not a likely pair to form an ionic compound because they are both nonmetals with similar electronegativities. Ionic compounds typically form between a metal and a nonmetal where the metal loses electrons and the nonmetal gains electrons to achieve stability.
Which pair of elements will combine to form an ionic compound?
An ionic compound is formed when a metal and a non-metal combine. For example, sodium (Na) and chlorine (Cl) combine to form sodium chloride (NaCl), which is an ionic compound.
Is PBr3 a molecular compound?
No. Since BH3 lacks a lone pair it would be a Lewis acid.
Which pair of elements will most readily form a compound?
Elements that are close to each other in the periodic table are more likely to readily form compounds. For example, sodium (Na) and chlorine (Cl) readily form the compound sodium chloride (NaCl) because they are adjacent to each other in the same period.
What is inertia pair?
An inertia pair is a pair of elements in a molecule that are related by a symmetry operation, typically a twofold rotation axis or a mirror plane. These elements have identical chemical properties and are often used to simplify the analysis of molecular symmetry.
Which pair of elements are most likely to form an ionic compound P and Br or Zn and K?
Zn and K are more likely to form an ionic compound because zinc (Zn) readily loses two electrons to form a 2+ cation, while potassium (K) readily gains one electron to form a 1- anion, allowing for the formation of an ionic bond between the two elements.
What does an empirical formula show?
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
What is the molecular weight of a DNA base pair?
The molecular weight of a DNA base pair is approximately 650 daltons.
What is the molecular weight of a base pair in DNA?
The molecular weight of a base pair in DNA is approximately 650 daltons.
What is the chemical formula and name of the ionic compound that can be formed from each pair of elements Ba and CI?
The chemical formula for the ionic compound formed from Ba and Cl is BaCl2, and the name of the compound is Barium Chloride.
What is the molecular geometry and electron pair geometry of SO2?
The molecular geometry of SO2 is bent, and the electron pair geometry is trigonal planar.
How many elements in the periodic table have lone pair of electron?
All elements in group 18 (noble gases) have a lone pair of electrons. Additionally, elements in groups 15, 16, and 17 have the potential to form a lone pair in their outermost shell depending on the specific chemical bonding situation.
What is the molecular structure of ammonia?
Trigonal pyramidal (see wikipedia article "Trigonal pyramidal molecular geometry" for a picture. In terms of VSEPR it is an AX3E compound so the three N-H bonds and the lone pair are approximately tetrahedrel- but as the lone pair repels a little more the bond angle is less than 109.50 at 1080
