1 mol zn ------------- 6.02x10²³ atoms
4.4 mol -------------- ??
4.4 x ( 6.02x10²³ ) / 1 => 2.648x10²⁴ atoms of zn
Answer:
ions
Explanation:
Individual atoms of the same element but having slightly different number of protons and electrons are called ions.
Ion is a charged particle.
- An atom is made up of three fundamental subatomic particles.
- Protons are the positively charged particles
- Electrons are the negatively charged particles
- Neutrons do not carry any charges.
When the number of protons > electrons the body is positively charged.
When the number of electrons > protons the body is negatively charged.
Charged particles are called ions.
In atomic models balls represent an atom
Now if an atom like carbon has four holes it means it can bond with four atoms. It has valency = 4.
The atomic number of carbon is 6
the configuration is 1s2 2s2 2p2
So due to four valence electrons it can bind with four other atoms and thus we have four holes in carbon ball
The hydrogen show a valency of one
the atomic number of hydrogen = 1
its configuration is 1s1
So it can bind with one atom (max) thus we have one hole in hydrogen ball
