Compounds
Explanation:
Reactive elements such as alkali metals and halogens are found in nature only as compounds. Such elements are too unstable to remain as stable atoms, therefore they readily combine and form compounds.
- Compounds are formed when two atoms combines together to share electrons.
- They either lose, gain, or share electrons between themselves.
- In the end, they end up becoming more stable.
- This is the reason why atoms combine.
- Unstable elements are very reactive especially alkali metals and halogens.
- On their own, they are unstable and prefers to bond with other atoms in order to gain a measure of stability.
- This is why they are found in combined state in nature.

Answer:
163.8 ft
Explanation:
In triangle ABD
= 155 ft


Using Pythagorean theorem in triangle ADC

= distance between the anchor points
distance between the anchor points is given as

T = 2 * pie √(L/g)
so, if length is increased by 9
then time period is increased by √9 = 3
hope it helped :)
The light must be either very dim or else non-existent.
We can't see the light wave or the label.
Answer:Bohr placed the electrons in distinct energy levels. Rutherford described the atom as consisting of a tiny positive mass surrounded by a cloud of negative electrons. Bohr thought that electrons orbited the nucleus in quantised orbits.
Explanation: also rutherfords was just a hypothesis while Bhor took the time to make his an experiment
