There are 17 nonmetals on the periodic table of elements.
I am probably wrong but I would think 900. I wouldn’t submit that without somebody backing me up though.
Answer:
1.21 × 10⁻³⁰ m
Explanation:
1 mol of photons causing the change in the conformation of 11-retinal has an energy of 164 kJ. We can find out the wavelength (λ) associated with this energy (E) using the Planck-Einstein equation.
E = h . c . λ⁻¹
where,
h is the Planck's constant
c is the speed of light
λ = h . c . E⁻¹ = (6.63 × 10⁻³⁴ J × s) × (3.00 × 10⁸ m/s) × (164 × 10³ J)⁻¹ = 1.21 × 10⁻³⁰ m
Calcium will lose 2 electrons to gain a full outer shell.
This will form a positive ion.
any ecosystem is consisted of biotic and abiotic parts. All living organisms like all types of animals and plants etc. and all other parts like soil, water, rocks, etc. are abiotic parts
