Answer:
False
Explanation:
The Avogadro's number is not used to determine the number of subatomic particles in an atom.
Subatomic particles of an atom are the protons, neutrons and electrons.
The protons are the positively charged particles in an atom
Neutrons do not carry any charges
Electrons carry negative charges.
The number of protons, neutrons and electrons in an atom are experimentally determine using spectrometric techniques.
Answer:
The pennies represent the particles of the isotope either decaying, or staying the same after each shake. This is a random process.
The answer is group 1A.
In the ionic compound formula X₂SO₄, SO₄ has a -2 charge. Hence to balance this -2 charge of SO₄, X must have a +1 charge.
Group 1A elements form X⁺ type of ions because they are metals. So, they have the tendency to lose electrons.
Hence, X must belong to the 1A group.
Ionic Compounds-
- Ionic compounds are formed by the electrostatic attraction between the anions and the cations.
- Cations are positively charged ions that are formed due to the loss of electrons.
- And the anions are negatively charged ions that are formed due to the gain of electrons.
- Due to this, they have opposite charges and form bonds known as Ionic Bond.
