Answer: They are arranged by atomic number.
Answer:
It decreases
Explanation:
As one moves from left to right on the periodic table, the radius of atoms reduces due to the nuclear pull.
- The size of an atom estimated by the atomic radius is taken as half of the internuclear distance between the two covalently bonded atoms of non-metallic elements.
- Across a period, atomic radius decreases progressively from left to right.
- This is due to the increasing nuclear charge without attendant increase in the number of electronic shell.
Answer:
Uh, the second one?
Explanation:
Try to restate the question please.
The characteristics of solids that is most responsible for their structure are:
1. BONDING PATTERNS BETWEEN ATOMS.
2. TYPES OF MATTER IN SOLIDS.
Solid state is one of the four states of matter that exist; the other three are liquid, gas and plasma. Solids generally have their constituent particles arranged in a regular pattern, which is known as crystalline structure. The crystalline structure of the solid is due to the types of matter and the chemical bonds that exist between the particles of solids. The constituent particles of a solid can be atoms, ions or molecules.
Answer:
CH4
Explanation:
The number of moles of carbon and hydrogen has been given as follows:
C = 0.300 mol
H = 1.20 mol
Next, we divide each mole value by the smallest (0.300)
C = 0.300 ÷ 0.300 = 1
H = 1.20 ÷ 0.300 = 4
The empirical ratio of Carbon and Hydrogen is 1:4, hence, the empirical formula is CH4
