No. It must reach the minimum threshold energy. Since its only half, there isn't enough energy for the electron to jump to the 2s energy level.
Side note: An electron can only jump between energy level if the minimum energy is met. If the energy of the photon does not meet this energy level and is below, the electron will not jump to the new level.
Protons = +1
negatrons = -1
neutrons = 0
<span>electrons = -1
</span>
<span>negatrons are like positrons and they are subatomic particles and are not present in atoms
</span>
so electrons are negatively charged and are present in atoms
hope that helps
2Ag⁺(aq) + Mg(s)→ 2Ag(s) + Mg²⁺ (aq)
<h3>Further explanation</h3>
Given
Standard cell notation:
Mg(s) | Mg2+ (aq) || Ag+(aq)| Ag(s)
Required
a balanced redox reaction
Solution
At the cathode the reduction reaction occurs, the anode oxidation reaction occurs
In reaction:
Ag⁺ + Mg → Ag + Mg²⁺
half-reactions
- at the cathode (reduction reaction)
Ag⁺ (aq) + e⁻ ---> Ag (s) x2
2Ag⁺ (aq) + 2e⁻ ---> 2Ag (s)
- at the anode (oxidation reaction)
Mg (s) → Mg²⁺ (aq) + 2e−
a balanced cell reaction
<em>2Ag⁺(aq) + Mg(s)→ 2Ag(s) + Mg²⁺ (aq)
</em>
Answer: 2116.8 seconds
Explanation:
0.0035 weeks × 7days/week × 24hrs/day × 60min/hr × 60sec/min
=2116.8 seconds
=2100 (if you are required to consider significant figures)
