Answer:
d. IF3
Explanation:
The Octet rule posits that atoms gain, atom lose, or share electrons in order to have a full valence shell of 8 electrons. This statement occurs when atoms also combine to form molecules until they attain or share eight valence electrons either by losing or gaining eletrons.
From the given options, a valid Lewis structure that cannot be drawn without violating the octet rule is IF3
The mass number is the sum of the protons and neutrons in an atom. 235-92 = 143 neutrons.
Element 92 is Uranium.
Uranium is also the highest atomic number element which exists in nature. All of the rest above element 92 only exist nuclear high-energy reactions (the transuranium elements), and most experience nuclear decay very quickly and form other elements with fewer protons.
True
As the shorter the bond, the stronger it is hence more energy will be required to overcome this bond
requires a medium to propagate
Explanation:
due to radiation z a dispersion of light ray into different multiple
The laws of the electrostatics were developed by Coulomb and are further detailed or subdivided into two as follows:
(1) The first one talks about the similarities in the charges of the particles and what happens to them. This states that like charges repel.
(2) The second one quantifies the field between two particles with equation showing that field is directly proportional to the masses and inversely to the square of the distance between them.
In this item, we can then say that the protons (having the same charges) will have to repel from each other in accordance to statement 1 of the law.
