No, Antoine Lavoisier is not correct to refer to charcoal as an element. Charcoal is not an element but rather a compound primarily composed of carbon. An element is a substance that cannot be broken down into simpler substances by chemical means, whereas a compound is composed of two or more elements chemically bonded together. Lavoisier's understanding of elements and compounds was foundational in the development of modern chemistry.
No. NZ is neither an element, as no element has only 2 letters. Also, it is not the initials of any element.
Sulphur is the British English spelling, while sulfur is the American English spelling for the same chemical element. Both terms refer to the same element on the periodic table with the atomic number 16 and symbol S.
CF does not correspond to an element on the periodic table. It may refer to "Californium," a synthetic element with the atomic number 98 and symbol Cf. Californium is a radioactive transuranic element.
There is no element with the symbol "hc." It is possible that the symbols "H" and "C" were combined, which would refer to hydrogen (H) and carbon (C), two separate elements on the periodic table.
The numbers 39, 40, and 41 after the element name potassium refer to the mass number of the isotopes of potassium. Potassium has three isotopes: potassium-39, potassium-40, and potassium-41, which have 19, 20, and 21 neutrons respectively.
The atomic number of an element refers to the number of protons.

To determine the correct order of element groups, it's essential to refer to the periodic table, where elements are organized into groups based on their chemical properties. The groups typically include alkali metals, alkaline earth metals, transition metals, halogens, and noble gases. Please specify the choices you are considering for a more accurate answer.

It could refer to a member of a set.
No, it is not grammatically correct. If you want someone to correct it for you, please can you explain what you are trying to refer to?
The word 'azote' is French for nitrogen. It's the name that was given to nitrogen by pioneering French scientist Antoine-Laurent de Lavoisier [26.viii.1743-8.v.1794]. The word comes from the Greek words for 'without life'.

It is correct when used to refer to a gay person. It is incorrect when used to refer to a straight person in order to insult them. It is also incorrect to use it as a synonym for stupid.

In the late 1770's, French chemist Antoine Lavoisier first used the term "oxygéne" to refer to a newly discovered element that could be used to make acids. The word came from the Greek root oxy-, meaning sharp or pungent, and -gen, meaning "that which creates." So oxygen means a substance that creates acids. The word was adopted into the English language as "oxygen."
