Answer:
if we're talking about beryllium then the answer should be 2 because it wants to move 2 spaces back (losing electrons) to become a Nobel gas so the answer is 2+
Explanation:
it has 2 valence electrons YW :)
The options for given question are as follow,
1) Methane molecules show hydrogen bonding.
<span>2) Ammonia molecules show hydrogen bonding. </span>
<span>3) Methane has stronger hydrogen bonding than ammonia. </span>
<span>4) Both the compounds do not show hydrogen bonding. </span>
<span>5) Both the compounds have strong hydrogen bonding.
</span>
Answer:
Correct answer is Option-2 (Ammonia molecules show hydrogen bonding).
Explanation:
Hydrogen bond interactions are formed when a partial positive hydrogen atom attached to most electronegative atom of one molecule interacts with the partial negative most electronegative element of another molecule. So, in Ammonia hydrogen gets partial positive charge as nitrogen is highly electronegative. While the C-H bond in Methane is non-polar and fails to form hydrogen bond interactions.
Answer:
D
Explanation:
We have to bear in mind that the acid is a weak acid. A weak acid does not dissociate completely in solution. We will have more concentration of undissociated acid than A^- and H3O^+ and OH^- in the system at equilibrium.
Being a weak acid, there is maximum concentration of water molecules followed by that of undissiociated acid.
Hence, for this solution, the concentration of ions in solution follows the order;
[H2O] > [HA] > [A-] ~ [H3O ] > [OH-]

A 780 gram element decays at a rate of 18% every minute. 780 elements are still missing (1-0.171) 19 .
Element:
<h3>What does that mean?</h3>
A basic object that is difficult to divide into smaller bits is described as an element. An element is a chemical that cannot be broken down by non-nuclear processes in physics or chemistry. A discrete component of a bigger structure or collection is referred to as an element in computers and mathematics.
<h3>Element and atom definitions?</h3>
The most basic form of a material is an element. In general, it cannot be streamlined or broken down into smaller parts. A constituent of an element is an atoms. A specific element only has one kind of atom per atom. Charged particles, neutrons, and electrons, which are particles, make up the remainder of an atom.
