When an atom or molecule accepts or looses an electron or electrons it gets either negative charge (when electrons gained) or a positive charge (when looses electron). The negative ion is called Anion and positve ion is called the Cation. An Ion can be Atomic or Polyatomic.
Example:
Sodium when looses one electron forms a cation i.e. Na⁺
Chlorine when gains one electron forms an Anion i.e. Cl⁻
Result:
<span>A negative ion (Anion) differ from an uncharged atom of the same element in the number of electrons. An anion contains more electrons than its corresponding Neutral Element.</span>

Answer:
Collecting residue samples.
Explanation:
All the other given options are equally important on the exploration of a bomb aftermath.
The most important task is the collection of residue samples since it needs highly skilled personel to collect accurate samples for later on analysis.
Identification of meaningful collection areas is a technical skill that requires the most experienced team memebers.
Answer:
9.03*10^23 atoms of C
Explanation:
1 mol of any substance contains 6.02*10^23 particle of this substance.
1 mol C --- 6.02*10^23 atoms of C
1.50 mol C --- x atoms of C
x = 1.50*6.02*10^23 = 9.03*10^23 atoms of C
Answer:
<h2>5080 mL</h2>
Explanation:
The volume of the gas at standard pressure can be found by using the formula for Boyle's law which is
Since we are finding the new volume
From the question we have
We have the final answer as
<h3>5080 mL</h3>
