Answer:
detail is given below.
Explanation:
The charged particles of nucleus are protons while neutrons are neutral having no charge.
We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus. Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg and 1.674929×10⁻²⁷ Kg respectively.
Symbol of proton= P⁺
Symbol of neutron= n⁰
The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons.
one proton contribute 1 amu to the total weight. There are 20 protons and 20 neutrons in Ca thus its atomic mass is 40 amu.
While the atomic number is 20.
The atomic number is 8 and the atomic mass is 16
The atomic number of the element is 8. This is because the atomic number is based on the number of protons or electrons. The atomic mass of the element is 16. This is because the atomic mass is equal to number of protons+the number of neutrons. Hope this helps.
The higher the degree of ionization, the stronger the conductivity
Answer:
The correct answer is;
b involves removing and refining waxy hydrocarbons called kerogen
Explanation:
Shale oil deposits are present in the United States in the Green River formation in Wyoming, Utah and Colorado and in the Devonian Oil shales in Kentucky, Tennessee, Ohio and Indiana.
Shale oil has boosted crude oil production since 2014 and the United states is presently one of the world's largest producers crude-oil.
Kerogen, found in oil shale is treated to produce shale oil with about 6.05 trillion barrels of oil in place globally.
Hello there!
The atomic number of an atom tells you an element's identity, and informs you of how many protons are present in the nucleus of the atom.
For example;
Potassium is an element with the symbol "K" on the periodic table that belongs in the Alkali Metal group, and has an atomic number of 19. This means that Potassium has 19 protons.
I hope this helps!
