The component of the atom specified wherein its mass is too small to be negligible is called an electron. In addition, this component of an atom has a mass of only 9.11 x 10 ^-31 kilogrammes. Due to these, the mass of the proton and the neutron which belongs to the nucleus of an atom gets carried out.

Balancing the equation
- An equation is a symbolic representation of a chemical reaction.
- A balanced chemical equation is an equation where the number of atoms of reacting elements is equal to the number of atoms of the product.
- The unbalanced equation for the reaction between methane and water:
→ 
- Here, the number of hydrogen atoms on either side of the arrow is unequal.
- To balance the equation, we multiply the molecule by 3. This makes the number of Hydrogen atoms equal(6 Hydrogen atoms).
- Thus, the balanced equation becomes:

Answer:
they're close to filling their outer shell, fulfilling the octet rule
Explanation:
Answer:
5.3 x 10⁻⁷ m
Explanation:
Data Given
frequency = 5.7 x 10¹⁴ Hz.
Convert Hz to per seconds (s⁻¹)
1 Hz = 1 s⁻¹
5.7 x 10¹⁴ Hz = 1 x 5.7 x 10¹⁴ = 5.7 x 10¹⁴ s⁻¹
wavelength =?
Solution:
Formula used to calculate wavelength
f = c/λ
rearrange the above equation
λ = c/f ........(1)
Where:
c = speed of light = 3 x 10⁸ ms⁻¹
λ= wavelength
put the values in above equation 1
λ = 3 x 10⁸ ms⁻¹ / 5.7 x 10¹⁴ s⁻¹
λ = 5.3 x 10⁻⁷ m
So the wavelength of light = 5.3 x 10⁻⁷ m
