Answer : Option A) Atomic number of Arsenic is 33.
Explanation : Arsenic contains same number of protons in its atomic nucleus. In arsenic there are 33 protons found in the atomic nucleus. Hence, the atomic number will be 33. It has 5 valence electrons in its outermost shell, which is also called as valence shell. So, its valency becomes 5.
The molar mass of M is 0.225g/mol and the element M is Hydrogen
If a metal M combines with an oxygen element to form the oxide,
then the chemical reaction will be expressed as:

This shows that 4 moles of an unknown element M react with the oxygen element to produce the oxide
Given the following parameters
Mass of M = 0.890 grams
Mass of
= 0.956 grams
Get the molar mass of M:
Molar mass = Mass/number of moles
Molar mass = 0.890/4
Molar mass = 0.225g/mol
Hence the molar mass of M is 0.225g/mol and the element M is Hydrogen

The melting point of ice is 0°C: thus is a fact based on repetitive experiments
Repeated observations have consistently
shown that oppositely charged objects
attract each other: this is law
When the elements carbon and nitrogen
are mixed at 1500°C, they will react
with each other.
this is a hypothesis
Atoms are made of protons, neutrons,
and electrons. Although we can’t directly
see these particles, this structure
explains many experimental observations
