Even a much smaller amount of only-protons would quickly blow up (move away from one another), due to their electric charge.
No.
Yes, humans are the only living species of the Homo sapiens genus. Other Homo species, such as Homo neanderthalensis, Homo habilis, and Homo erectus, have gone extinct.
Humans have existed for only about 0.2% of Earth's history, which is approximately 200,000 years out of Earth's 4.5 billion-year history. This indicates that humans are a relatively recent addition to the planet.
Homo sapiens, or humans, are widespread and can inhabit a wide range of environments, from tropical rainforests to arctic tundras. Humans have developed the ability to adapt and thrive in various habitats through the use of tools, shelter, and social organization. Today, humans primarily inhabit urban and suburban areas, but continue to live in diverse environments around the world.
No, it is not for only humans. It existed long before humans appeared and will exist long after we are gone; in that time, it has, is and will support hundreds of millions of other types of organism.
A battery is the storage of energy invented by humans and is filled with chemicals.

The first and only filled shell has two electons. The nucleaus has two protons. He-4 also has two neutrons.
Protons of an atom are found only in its nucleus.
They don't. Sinkholes are filled in.
Radium has 88 protons, radon has only 86 protons.
Some pencil's are filled with lead, but rarely any nowadays. Pencils use to be filled with lead, but now pencils are typically filled with graphite as lead is poisonous to humans.
No, carbon can not have 8 protons. The number of protons in an element can not vary. Carbon can only have 6 protons (the atomic number). If an element has 8 protons, it is oxygen.
Iron (Fe) is the only element which has 26 protons.
Many things. Humans, for one. We are filled with water and stand. Cups are another. They stand on a table and are filled with water.
It is the ratio of neutrons to protons that generally determines the stability of an isotope.
Protons are not located in orbitals. Only electrons are present in the orbitals. Protons and Neutrons are located inside the nucleus of an atom.
