How did lavoisier distinguish between compounds and elements?
he used the amount of atoms in each element and compound.
Radioactive element used for nuclear energy?
One of the radioactive elements used for nuclear energy is 235U92, commonly stated as U-235.
How do you find the number of carbon moles in cholesterol c27h46o?
The number of atoms of an element in a molecule is the number subscript immediately following the element symbol in the formula for the molecule. The number of moles of anything in a compound depends on the amount of the compound, which is not stated.
What is the nuclear symbol for an element with 9 protons and 10 neutrons?
Oxygen has 6 protons and 8 neutrons (symbol O).
What elements have 4 energy levels?

Does an element's number of valence electrons equals the element's number of protons?
Only hydrogen and helium have the stated property. For all heavier elements than these two, the number of valence electrons is less than the total number of electrons, which must be the same as the number of protons in all neutral atoms.
How do you estimate the number of neutrons in the atoms of an element?
The number of neutrons in the nucleus of an atom of any isotope of an element is equal to the "atomic mass number", which is usually stated in a number immediately after a hyphen at the end of the element name in the name of the isotope, minus the atomic number. Because most elements have more than one stable isotope, the average number of neutrons in the mixture of isotopes of an element that occurs naturally is usually not an integer.
What is the average number of comparisons in a sequential search?
If this is a homework related question, you really should consider trying to solve it yourself before looking at this answer. Otherwise, the value of the lesson, and the reinforcement provided by the assignment, will be lost to you. In a sequential search, where the elements are in a uniformly random distribution, the average number of comparisions to find a particular element is one half of the number of elements. Stated another way... In a sequential search, where the elements are in an arbitrary distribution, the average number of comparisions to find a random element is one half of the number of elements.

Which of these elements is the smallest element sodium potassium rubidium or cesium?
Of the Group 1 elements stated (Na, K, Rb, Cs), Caesium is the largest as it is the furthest down the group, and Sodium is the smallest of those as it is furthest up the group.
What are the atomic number and atomic mass of the isotope Br 79?
The atomic number of any bromine atom is 35, and the atomic mass number is the number stated after the element name in the question, in this instance 79.
What represents an element in an atom?
Nothing. The question is wrongly stated. Each single atom is an element.

Who is the scientist mosley?
in 1914 Henry mosely stated the modern periodic law. He said that when the elements are in order of increasing atomic number (number of protons) they show a periodicity or repeating pattern of properties.
