# How many protons does uranium-235 have?

## How many protons does uranium-235 have?

92 protons
Uranium-235 has 92 protons.

## How many protons and electrons does uranium-235 have?

Uranium-235 is a naturally occurring isotope of uranium, an element characterized by having 92 protons in its nucleus. As all uranium nuclei have 92 protons, the nucleus of a uranium-235 atom will also have 143 neutrons to give it a total atomic mass number of 235.

How many protons does oxygen have?

8
Oxygen/Atomic number

### How many protons neutrons and electrons are in uranium-235 use a periodic table?

Uranium is the heaviest of the naturally occurring elements. It can be found in row seven of the periodic table and is a member of the actinide group. Uranium atoms have 92 electrons and 92 protons with six valence electrons. There are 146 neutrons in the most abundant isotope.

### Is uranium-235 rare?

Nuclear power plants use a certain type of uranium—U-235—as fuel because its atoms are easily split apart. Although uranium is about 100 times more common than silver, U-235 is relatively rare at just over 0.7% of natural uranium.

How many protons and neutrons are in 235 is over 92u?

Find the number of neutrons in the isotope by subtracting the number of protons from the mass number given in the symbol. For example, 235U, which contains 92 protons, therefore contains 235 – 92 = 143 neutrons.

#### What is the percentage of fissionable U-235 occurring in uranium?

Explanation: naturally occurring uranium contains only 0.7% of fissionable u-235, which is not enough for most types of rectors. it is necessary to increase the amount of u- 235 by enrichment, although it is a difficult and expensive process.

How many protons do each of the following atoms have oxygen?

The oxygen atom has therefore 8 neutrons, 8 protons and 8 electrons.

## How many neutrons are there in oxygen?

Oxygen-16

General
Symbol 16O
Names oxygen-16, O-16, Oxygen – 16
Protons 8
Neutrons 8

## How many neutrons does uranium-235 have?

143 neutrons
The nucleus of the U-235 atom comprises 92 protons and 143 neutrons (92 + 143 = 235).

Where do you find uranium 235?

Where does it come from? U-235 and U-238 occur naturally in nearly all rock, soil, and water. U-238 is the most abundant form in the environment. U-235 can be concentrated in a process called “enrichment,” making it suitable for use in nuclear reactors or weapons.

### How many protons and neutrons are in uranium 235?

How many protons and neutrons are in uranium 235? – Answers Neutrons 143 Protons 92 92+143=235 For other isotopes: number of neutrons = Atomic Mass (or mass number) – number of protons

### What is the number of neutrons in 92 protons and neutrons?

– Answers Neutrons 143 Protons 92 92+143=235 For other isotopes: number of neutrons = Atomic Mass (or mass number) – number of protons

What is the number of protons and electrons in the atom?

The number of protons is the atomic number. 92 is correct. The number of electrons is the same as the number of protons which must be 92. The number of neutrons is mass number-atomic number = 235-92=143.

#### How many of the original uranium-235 remains in the rock?

Suppose you find a rock and chemical analysis tells you that only one sixteenth of the​ rock’s original​ uranium-235 remains. How old is the​ rock? 1. An atom has 3 protons, 4 neutrons, and 3 electrons.
