8 0

Answer:

<h2>A good example of a fixed pulley is a flag pole: When you pull down on the rope, the direction of force is redirected by the pulley, and you raise the flag. ... Examples of movable pulleys include construction cranes, modern elevators, and some types of weight lifting machines at the gym.</h2>

Answer:

N - 1s²2s²2p³

Explanation:

Nitrogen is located in the p-block of the periodic table (groups 13-18) and is on the 2nd period.

The 2nd period tells us the principal energy level (a quantum number) is n = 2. Therefore, it must have already filled up the 1s sublevel.

The groups 13-18 on period 2 tells us that the 2s sublevel is also filled.

Nitrogen is located in Group 15. That means that there are 3 electrons that have filled the 2p sublevel, out of a possible 6.

Therefore, our electron configuration is 1s²2s²2p³

2p³ (Shorthand Config)

[He] 2s²2p³ (Noble Gas Config)

Beryllium has a nucleus composed of protons and neutrons. Given the data, how many protons are in a typical Beryllium nucleus?
Jlenok [28]

Atoms are made of 3 types of subatomic particles ; protons, neutrons and electrons

protons and neutrons are located inside the nucleus and electrons are found in energy shells around the nucleus. Protons are positively charged, electrons are negatively charged and neutrons are neutral. elements in their ground state are neutral with equal amounts of protons and electrons.

Atomic number is the number of protons. atomic number is characteristic for the element.

atomic number of Be is 4 therefore Be has 4 protons

answer is B. 4
