The periodic table of elements is divided into columns and rows. The vertical columns represent the groups while the horizontal rows represent the periods. A group of elements usually have similar physical and chemical properties. The first column of the periodic table is made up of 7 elements including SODIUM.
1. The name of the element chosen is sodium and its chemical symbol is Na.
2. Sodium is a metal and thus it has metallic properties.
3. Sodium belongs to group one elements whose family name is ALKALI METALS.
4. The neutral atom of sodium is made up of 11 protons, 11 electrons and 12 neutrons.
The reagent which is used is "NaI", that is Sodium iodide.
When the reagent sodium iodide is added to distinguish the Ag⁺ ions and Fe³⁺ ions, it will react and form precipitate with one, while have no precipitates formed with the other, so that is how we can distinguish both of them.
Answer:
C 2
Explanation:
2Nal + Cl2 → 2NaCl + I2
This is balanced equation
- Nitrogen as in NH₃.
- Phosphorous as in PH₃.
<h3>Explanation</h3>
Hydrogen is in group 1. It is one electron away from the next noble gas element. It would form one single covalent bond when it bonds to nonmetals.
A nonmetal atom will gain three extra electrons when it bonds to three hydrogen atoms. For the molecule to be stable, that nonmetal atom should be three electrons away from the next noble gas element. Each of the atoms in question should contain 8 - 3 = 5 valence electrons when neutral. Which column on a periodic table contains such elements?
Answer is: CH₃-CH₂-CH₂-NH₃⁺.
Amine group (-NH₂) has neutral charge, bet when accepts one proton (H⁺) has positive charge.
