The elements above Atomic number 86 generaly redioactive.

As atomic number represents the number of protons,above A.N 86 the elemens will be radio active in specific conditions.exception,C-13 is a radioactive isotope of carbon.

The electron shells in gold and the number of electrons in each one are as follows: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2 4d10 5p6 4f14 5d10 6s1 Gold has 79 electrons in its neutral state, one for every proton in its nucleus. Because this is a lot of "work" to write out, we often "abbreviate" the electron configuration notation. We do this by writing the chemical symbol of the noble gas with an atomic number below that of the element we wish to identify, and then just "add the rest" of the electron notation above that. We call this noble gas notation or configuration. For gold, the noble gas below gold on the periodic chart is xenon (Xe). Here's the "new" notation (using xenon as an identifier) for the gold: [Xe] 4f14 5d10 6s1 Note that the three shells beyondxenon that describe gold (4f14 5d10 6s1) are identical to the last three in the "long version" of the notation. They must be, as both are expressions of the electron configuration of gold. Wikipedia has additional information of gold, and a link is provided.

A carbon atom has 6 protons, 6 electrons and 6 neutrons

More the number of shells in an atom, more away will be the electrons from the nucleus. Hence, weaker will be the attraction between nucleus and outermost electrons. So atom with more shells will let go their electrons easier than atoms with fewer shells.

The corona is able to stop most subatomic particles from escaping into space due to its strong magnetic fields that can trap and redirect charged particles. Despite being less dense, the corona's magnetic fields play a crucial role in retaining particles within its boundaries.

hydrogen (H) and helium (He)

If a quark has a length of 1×10-18m, and if the volume of a quark could be calculated by using this length as it's diameter, then:

The volume of a quark would be 5.236x10-49m

And if the volume of the sun is about 1.409 x 1018km3 (or 1.409x1027m3), then the number of quarks that could fit in the sun would be:

1.409x1027m3 / 5.236x10-49m3 = 0.269x1076 or 2.69x1075 or 2.69 Quattuorvigintillion quarks.

It should be noted that this is an approximate number, based on the length of an up-quark or a down-quark. As well, the volume for the sun is also approximate.

The electrons in an atom determine how it interacts with other atoms. Electrons are negatively charged particles that orbit the nucleus of an atom in specific energy levels, and their arrangement and movement play a key role in chemical bonding and interactions between atoms.

This particle is the electron with a mass of 5,485 799 094 6(22)×10−4 amu.

The total mass of 6 protons and 6 neutrons would be 12.092166 u (6 protons x 1.007276 u + 6 neutrons x 1.008665 u). The actual mass of carbon is 12 u, so the mass defect would be 0.092166 u (12.092166 u - 12 u).

HCN, hydrogen cyanide, has a total of 10 valence electrons. Hydrogen contributes 1 valence electron, carbon contributes 4 valence electrons, and nitrogen contributes 5 valence electrons.

Yes. And when this occurs, they will collide and annihilate one another.

A bismuth atom has 6 electron shells.

A joule is the work done by applying 1 watt of power for 1 second (J = W x Time in seconds).

1 Watt is 1 Amp at 1 Volt potential (W = Amps x Volts).

1 Amp is 1 coulomb of electrons flowing in a second.

1 coulomb is 6 241 509 629 152 650 000 electrons.

Thus it would appear that there are 6,241,509,629,152,650,000 electrons in a joule, except that 1 Joule could be 2 watts for half a second (or 4 W for 0.25 seconds).

Also 1 Watt could be 2 Amps and half a volt, or .01 Amps at 100 Volts!

The question has no one answer, it has an infinity of possible answers unless more parameters are dictated.

The subatomic particles in an atom are protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons orbit around the nucleus in various energy levels or shells.

Free electrons most definitely repel each other.

Any attempt to create a buildup of electrons in a specific spot will eventually result in the repulsion amongst these electrons to overcome the attempt to collect them.

When you rub your skin against a wool rug on a dry day, you build up a surplus of free electrons on your skin. The repulsion between these free electrons cause this surplus to scatter to all parts of the skin, thus permitting a discharge of them to occur at any place in your skin.

Repel, because like charges repel each other

Three different types of neutrinos are recognized.

The latest work on the subject suggests that the combined mass

of one of each type adds up to less than one billionth of an AMU.

In an atom of Cl, there are 7 valence electrons. If you look at a Chemistry Reference table (2002 edition) pages 8 and 9, (visit the link below), you can see that underneath Cl there are the numbers 2-8-7. The last number is the number of valence electrons. This is found for any element on the Period table.

Oxygen can ionize by losing electrons to form a positively charged ion. This can occur when an oxygen atom gains enough energy to overcome the attraction of its electrons, causing one or more electrons to be ejected from the atom. The resulting oxygen ion will have a positive charge due to the loss of negatively charged electrons.

The nucleus is one the order of one fermion in diameter.

The nearest electron orbital is on the order of more than a thousand fermions from the nucleus.

To me, that pretty far away.

Potassium-40 (K-40) has 19 protons and 21 neutrons.

Fluorine has 9 protons and 9 electrons. The number of neutrons can vary, as there are different isotopes of fluorine, but the most common isotope, fluorine-19, has 10 neutrons.

No, although their respective charges are exactly equal in size, they are opposite in sign.

The only subatomic particle that has any role in chemistry is the electron.
