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.
Option c would be the correct answer
Answer:
17 protons, 20 neutrons, and 17 electrons.
Explanation:
A periodic table can be defined as the standard arrangement of chemical elements by atomic number, electronic configuration and chemical properties in a tabular form.
Generally, a proper representation of the mass number and atomic number of chemical elements is key and very important in chemistry.
Furthermore, as a rule, it should be noted that the mass number (nucleon number) is always larger than the atomic number(number of proton).
The mass number of this neutral atom of Cl-37 is 37 and we know that the atomic number (number of protons) of chlorine is 17. Also, the atomic number of an element is equal to the number of its electrons.
A neutral atom of Cl-37 has 17 protons, 20 neutrons, and 17 electrons.
Hence, a neutral atom of Cl-37 can be identified based on its number of protons because it represent its atomic number, which is what is used to differentiate an atom of an element from the atom of another chemical element.
Answer:
i dont know but it is probily 4 and 6
Answer:
0.0626 M
Explanation:
Equation of the reaction
CH3COOH(aq) + NaOH(aq) ---------> CH3COONa(aq) + H2O
Concentration of acid CA= ???
Concentration of base CB= 0.1943 M
Volume of acid VA= 10.0ml
Volume of base VB= 32.22 ml
Number of moles of acid NA= 1
Number of moles of base NB= 1
From
CA= CB VB NA/VA NB
Hence ;
CA= 0.1943 M × 32.22 ml × 1/10.0ml ×1
CA= 0.0626 M
