The statement which is true about the three sub atomic particles is
X is a neutron,Y is a protons and z is an electron
<u><em>Explanation</em></u>
- Atom has three sub atomic particles,that is neutrons,protons and electrons.
- Neutrons have no electric charge,protons are positively charged while electrons are negatively charged.
- Both neutrons and proton are located in the nucleus while electrons are located outside the nucleus.
- since electrons are located outside the nucleus they orbit around the nucleus.
Answer:
20 km
Explanation:
he walks 10 km + another 10 km so 20 :)
Answer:
1 L
Explanation:
ppm means parts per million. Generally the relationship between mass and litre is given as;
1 ppm = 1 mg/L
This means that 1 ppm is equivalent to 1 mg of a substance dissolved in 1 L of water.
Knowing that a no orbital can accommodate more than two electrons,we can predict the maximum number of electrons in each layer or sub-layer ,It is possible <span>when :
* </span>Only two electrons can be assigned to an s orbital<span>.
* </span>three orbitals in a sub-layer p can accommodate two electrons, this sublayer can accommodate a maximum of six electrons.
* The five d orbitals of a sub-layer can accommodate a total of ten electrons.
hope this helps!
