Answer:
Ni^2+
Explanation:
The following data were obtained from the question:
Proton = 28
Electron = 26
Neutron = 34
Next, we shall determine the atomic number of the element.
Atomic number of an element is simply defined as the number of protons in the atom of an element.
Thus,
Atomic number = proton number
Proton = 28
Atomic number = proton number = 28
Atomic number = 28
Therefore, the element is Nickel since no two elements have the same atomic number.
Finally, we shall determine the charge on the Nickel atom as follow:
Proton = 28
Electron = 26
Charge on atom =
Charge on atom = Proton – Electron
Charge on atom = 28 – 26
Charge on atom = +2
Therefore, we can represent the Particle as Ni^2+
Answer:
There is the same amount of matter before and after the reaction
The atoms are arranged in different compounds and molecules.
There are the same types and number of atoms before and after the reaction
Explanation:
--The same amount of matter before and after the reaction and the same types and number of atoms before and after the reaction is because of the law of conservation of mass. Matter cannot be created or destroyed.
--the reacting atoms and molecules will undergo a transformation to different molecules and compounds. Can be predicted because of the types of chemical reactions:
combination (combining 2 elements to create a new compound)
Decomposition (a compound breaking down into different parts)
Single and Double displacement (the molecules/ atoms will change who they are paired with)
Charges is then there is a negative sign at the right corner of an element it means you have to add, and when it is positive, it means you have to substract
