What element has 9 protons neutrons and electrons?

Fluorine

## What does F 18 decay to?

Fluorine-18 (18F) is a fluorine radioisotope which is an important source of positrons. It has a mass of 18.0009380(6) u and its half-life is 109.771(20) minutes. It decays by positron emission 97% of the time and electron capture 3% of the time. Both modes of decay yield stable oxygen-18.

## How many isotopes does f have?

Isotopes of fluorine. Although fluorine (9F) has 18 known isotopes from 14F to 31F and two isomers (18mF and 26mF), only one of these isotopes is stable, that is, fluorine-19; as such, it is a monoisotopic element. The longest-lived radioisotope is 18F with a half-life of 109.771 minutes.

## What are the names of the stable forms of oxygen?

Stable isotopes. Naturally occurring oxygen is composed of three stable isotopes, 16O, 17O, and 18O, with 16O being the most abundant (99.762% natural abundance); thus oxygen (O) has a relative atomic mass of 15.9994(3). Known oxygen isotopes range in mass number from 12 to 24.

## How many protons neutrons and electrons are in an atom of beryllium?

Beryllium has atomic number 4, which means it has 4 protons in its nucleus, and 4 electrons in its orbitals (in the configuration 1 s 2 2 s 2 ). The only stable isotope of Beryllium is 9 B e , which has 9 − 4 = 5 neutrons in the nucleus.

## What are two conclusions supported by Rutherford’s experiment?

The results of this experiment gave Rutherford the means to arrive at two conclusions: one, an atom was much more than just empty space and scattered electrons (J.J. Thomson model argued), and two, an atom must have a positively charged center that contains most of its mass (which Rutherford termed as the nucleus).

Fluorine

## Which atom has an atomic number of 26?

iron is the 26th element in periodic table. iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth’s outer and inner core.

## Is fluorine stable or unstable?

Fluorine bonds with almost any element, both metals and nonmetals, because it is a very strong oxidizing agent. It is very unstable and reactive since it is so close to its ideal electron configuration.

## Can you change the number of protons in an atom?

Can the number of protons in an element ever change? A. No, protons and neutrons are bound together in atomic nuclei, and neither can change. B. Yes, isotopes of the same element have different numbers of protons. C. No, if the number of protons changes, the element changes.

## How many neutrons are in F 19?

Fluorine stable isotope number 1 19 f. Neutrons 10;19 oct 2015 this isotope of fluorine has 9 protons, electrons and 10 neutrons 19 mar 2016 since the number equal meanwhile, it’s mass 19, minus neutrons, gives you 5 dec normal florine is amu. Protons, neutrons, electrons fluorine 19 004 youtube.

## How many electrons does f have?

So for the element of FLUORINE, you already know that the atomic number tells you the number of electrons. That means there are 9 electrons in a fluorine atom. Looking at the picture, you can see there are two electrons in shell one and seven in shell two.

## How many neutrons are there in nitrogen?

Using information found on the Periodic Table of Elements, we can tell that an average atom of nitrogen contains 7 protons, 7 neutrons and 7 electrons. Now that you know how many protons, neutrons and electrons you will need for your model, it is time to decide what to use to represent them.

## What is the number of neutrons in fluorine?

NameFluorineAtomic Mass18.998 atomic mass unitsNumber of Protons9Number of Neutrons10Number of Electrons9

## What is the number of neutrons in a neon atom?

NameNeonAtomic Mass20.1797 atomic mass unitsNumber of Protons10Number of Neutrons10Number of Electrons10

## Which accounts for most of the mass of an atom?

These particles, for the sake of simplicity, are protons, neutrons and electrons. The center or nucleus of an atom contains protons and neutrons that account for nearly all the mass of an atomboth protons and neutrons have masses equal to one atomic mass unit (amu or Dalton).

## How many electrons are in the f orbital?

This tells us that each subshell has double the electrons per orbital. The s subshell has 1 orbital that can hold up to 2 electrons, the p subshell has 3 orbitals that can hold up to 6 electrons, the d subshell has 5 orbitals that hold up to 10 electrons, and the f subshell has 7 orbitals with 14 electrons.

## How many neutrons are in an atom of chlorine?

An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 particles in the nucleus). Adding or removing a neutron from an atom’s nucleus creates isotopes of a particular element.
