Explanation:
The atomic radius of a non metal is larger than its neutral atom. Because the nonmetal have a tendency to gain electron and on gaining electrons, the electrons tend to repel each in the orbital.Hence, the size is increased.
The atomic radius tends to decrease from left to right as the nuclear charge increases the shielding of inner core electrons remain the same. The increased attraction of nucleus for its electrons pulls the electron inward. thus decreasing the size of atom.
N has more ionisation energy than Li
Ne has more ionisation energy than Kr
Li has more ionisation energy than Cs
Exergonic reactions release energy; endergonic reactions absorb it.
Answer: formic acid
Explanation:
HCOOH is the structural formula for the compound commonly known as formic acid.
According to the international union of pure applied chemist (IUPAC), it is named methanoic acid, and represent the first member of the alkanoic acids.
Thus, examples of alkanoic acids are
- formic acid (HCOOH)
- Acetic acid (CH3COOH)
- Propanoic acid (CH3CH2COOH) etc
- We cannot change protons of any element
- So the atomic number is 33
- The element is Arsenic(As)
Now here is 36 electrons so it's. tri cation.
