Explanation

To determine the symbol of element B with five protons and six neutrons, we can follow these steps:

The number of protons (atomic number) determines the element. An element with five protons is boron (B).

The mass number (A) is the sum of protons and neutrons. For this element, it is 5 + 6 = 11.

Therefore, the symbol for this element is 11B.

Explanation

The nucleus, which consists of protons and neutrons.

It is incredibly dense and occupies a very small volume compared to the extra-nuclear part (electrons).

However, the nucleus contains most of the atom's mass due to the significant mass of protons and neutrons.

Explanation

Protium (1H) is the lightest isotope of hydrogen, and it has no neutrons.

Its atomic nucleus consists of only one proton.

• Protons: 1
• Neutrons: 0
• Electrons: 1

Explanation

The symbol Z represents the proton number.

It is also known as the atomic number, which defines the element.

The symbol A represents the mass number (protons + neutrons).

Explanation

Mass number (237) = Number of protons (92) + Number of neutrons

Number of neutrons = Mass number - Number of protons

= 237 - 92

= 145

Therefore, the isotope 92U^237 has 145 neutrons.

Explanation

The atomic mass (also known as atomic weight) of an element is the total mass of protons and neutrons present in the nucleus of an atom.

This includes:

• Mass of protons (which defines the element)
• Mass of neutrons (which varies in different isotopes)

Explanation

All the isotopes of the same element have the same number of protons, which defines the element.

Different isotopes can exist depending on the neutron count.

Electrons are negatively charged and can counterbalance the positive charge of protons.

Also, they are present in equal numbers in neutral atoms of the same element.

• JPEG (Joint Photographic Experts Group) is a file format used for images, not text documents.
• It's commonly used for photos and graphics.

The file extensions suitable for MS Word files:

• .doc: An older file format used by MS Word (up to version 2003).
• .rtf: Rich Text Format, a file format that can be opened by MS Word and other word processing software.
• .docx: The current file format used by MS Word (version 2007 and later).

Explanation

An algorithm is a sequence of instructions in a computer language that is designed to solve a specific problem or achieve a particular goal.

It's a step-by-step procedure to get the desired results.

Explanation

• A LAN is a computer network that connects devices in a limited geographical area, such as an office building, campus, or home.
• It's perfect for connecting different computers in an organized manner within an office building.

Note:

• MAN (Metropolitan Area Network): Covers a larger area, like a city or town.
• WAN (Wide Area Network): Covers a vast geographical area, like a country or continent.
