Answer:
Option (d) is correct
N³⁻ > F⁻ > Mg²⁺ > Si⁴⁺
Explanation:
Total electrons for all the species = 10
So these are <u>iso electronic</u> with each other.
We know
Ionic radii ∝ 
- Si⁴⁺ has 14 protons and 10 electrons
- Mg²⁺ has 12 protons and 10 electrons
- N³⁻ has 7 protons and 10 electrons
- F⁻ has 9 protons and 10 electrons
- Iso electronic species with greatest number of protons have small size and vice versa.
- So Si⁺⁴ have smallest size and N³⁻ have largest in size
Answer:
1. Salt is a compound
2. CO2 is a compound
3. Gold is an element
4. Na is an element
5. Oxygen is an element
6. C6H2O6 is a compound
Explanation:
if it is on the periodic table it is an element
Explanation:
Given parameters
Period = 2.34minutes
Unknown:
Frequency of the oscillator = ?
Solution:
Frequency is the number of waves that passes through a point at a given time. It is the inverse of period which is the time it takes for a wave to pass through a medium:
F = 
F is the frequency
T is the period
To solve this, convert the period to seconds:
2.34minutes to seconds:
1 min = 60seconds
2.34 = 60 x 2.34 = 140.4s
F = 
= 0.007hz or 0.007s⁻¹

Answer:
They have no charge
Explanation:
Basically, They are just there to balance out the number of atoms. But, they don't really do anything else.
