Yes it’s correct.
An ionic bond is the transfer of electrons from a metal to a non-metal.
1. all elements are made of small particles called atoms
2. atoms of one element are identical in their properties, different atoms from different elements differ in properties
3. chemical reactions consist of atoms rearranging in whole number ratios
4. atoms can not be subdivided, created, or destroyed
Answer: The nuclide symbol of X is 
Explanation:
The given nuclear reaction is a type of alpha decay process. In this process, the nucleus decays by releasing an alpha particle. The mass number of the nucleus is reduced by 4 units and atomic number is also decreased by 2 units. The particle released is a helium nucleus.
The general equation representing alpha decay process is:
For the given equation :
As the atomic number and mass number must be equal on both sides of the nuclear equation:
Thus the nuclide symbol of X is
Answer:
Exothermic Reactions.
Explanation:
Reactions that release energy are called exothermic reactions.
Whereas that absorb energy are called Endothermic reactions.
More energy is being released to the surroundings than was absorbed to initiate and maintain the reaction in case of exothermic reactions.
Burning of a candle is an exothermic reaction.
