Q. Which is the most active element in periodic table?
Fluorine
Q. Which group of the periodic table contains the most active metals?
1 Answer. The family that contains the most reactive metals are the alkali metals.
Q. What will happen if you combine 2 hydrogen atoms?
It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. In the process some of the mass of the hydrogen is converted into energy.
Q. How do you add two atoms together?
Atoms can combine into ionic lattice structures or into covalent molecules. When different types of atoms combine, the result is called a compound.
Q. Why are many elements more stable as ions?
Many elements are more stable as ions than they are as atoms because as ions they lose or gain an electron. This change allows them to have full outershell of valence electrons. They are stable due to their full outershell of valence electrons.
Q. How do you know if an ion is stable?
The stability of ionic compounds depends on how easily one atom of the compound can gain electrons and how easily another atom of the compound can lose electrons….
- Charge on the ions.
- Size of the ions- larger the anion and smaller the cation, more is the stability of the compound.
- Ease.
Q. Why are ions more stable than atoms Class 9?
Ions are more stable because their valence shell is fulfilled and therefore no sharing or bonding of electrons take place. While atoms do not have fulfilled valance shell and so, Ions are considered more stable. Ions are more stable than atoms.
Q. How does hydrogen become stable?
Yes, hydrogen does become stable by losing an electron.
Q. Why is the ground state hydrogen stable?
Atoms of hydrogen have a single proton in their center and a single electron in the lowest energy level. The lowest energy level is filled with its maximum number of electrons. This is a very stable arrangement, and helium in consequence is an inert gas with few chemical properties.
Q. Why does hydrogen only want 2 electrons?
7. Hydrogen atoms follow the duet rule (not the octet rule). This is because it has only one shell and this shell can only hold 2 electrons.
Q. Why does hydrogen lose an electron?
-In general electron counting, H is small and so having no electrons is more stable than having 2 electrons than having 1 electron. -2e in small cloud around H is more high energy than 0e around that H so in most cases it is energetically efficient to lose 1e rather than gain it.
