By changing the number of protons in an element, you are fundamentally changing it to a different element.
It’s worth remembering that:
Protons identify the element
Electrons determine properties and behavior of the element
Neutrons contribute to isotopes and just help keep everything stable, by separating the charges. Remember opposites attract. Like charges repel.
The boiling point of chloroform is 61.2 C or 142.2 F. Please mark as brainliest if this helped you out :).
When an atoms oxidation number decreases in a reaction then it’s being reduced. the answer for that question is B
Answer:
they have differnet properties that repeat across the next period
Explanation:
Answer: It takes 193000 seconds to plate out exactly 1.00 mol of nickel metal, assuming 100 percent current efficiency.
Explanation:
1 electron carry charge=
1 mole of electrons contain= electrons
Thus 1 mole of electrons carry charge=


of electricity deposits 1.00 mole of nickel

where Q= quantity of electricity in coloumbs = 193000 C
I = current in amperes = 1.00 A
t= time in seconds = ?


Thus it takes 193000 seconds to plate out exactly 1.00 mol of nickel metal, assuming 100 percent current efficiency.
