The answer is D because the box b's force to the left is not being cancelled out and box d's force is trying to be cancelled out, but he has more force going up then down so he is moving up
Covalent bonds are formed between atoms which have
<span>- unsatisfied valency </span>
<span>- no inert gas electronic configuration </span>
<span>- These are directional bonds </span>
<span>- formed by sharing of electrons </span>
<span>Intermolecular forces </span>
<span>- much weaker than covalent bond </span>
<span>- These are not directional (except Hydrogen bonds) </span>
<span>- These are more electrostatic in nature </span>
<span>- exist between stable molecules </span>
<span>- can be Hydrogen bonding, dipole-dipole and induced dipole-induced dipole </span>
Alkali metals have only one valence electron and so have low binding energy to the metallic crystal lattice. ... A lower amount of energy needed to break a bond means a lower melting/boiling point.
Answer:
so you can do the maths your self
Explanation:
isotopes are elements with he same proton number but difference in their neutron number
- proton number is also known as the atomic number
- mass number is the sum of the proton number and the neutron number
- mass number = proton number + neutron number
Answer:
An electron has more mass than a proton or a neutron.
Explanation:
Mass of electron - 9.109 e-31 kg
hope it helps!!
