Answer:
Avogadro's number
Explanation:
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
It means 1 mole of any substance contain 6.022 × 10²³ number of representative particles.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
35.45 g Cl⁻ = 1mole = 6.022 × 10²³ Cl⁻ ions
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
The element fluorine (F) is the most reactive nonmetal.
A. Dalton - John Dalton created the very first atomic theory. Dalton viewed atoms as tiny, solid balls. His atomic theory had 4 statements:
1. Atoms are tiny, invisible particles.
2. Atoms of one element are all the same.
3. Atoms of different elements are different.
4. Compounds form by combining atoms.
B. Thomson - Thompson believed atoms were made mostly out of (+) charged material, like dough in a bun. The (-) charged electrons are found inside the (+) dough.
C. Rutherford - Rutherford discovered protons and the nucleus. He showed that atoms have (+) particles in
the center, and are mostly empty space. He called these (+) particles protons. He called the center of atoms the nucleus.
