Look for the highest numbered atom in the group: radium. Also barium has an empirical radius similar to the radius of radium: 215 pm.
Well, atomic is something to do with atoms, and radium is an element of the periodic table. All elements are atoms, so basically, saying atomic radium is like saying atomic atom (since radium is an atom). I don't know where you heard that, but it will be much more simple to only say radium instead of atomic radium, because they mean the same thing.
Radium has 7 "shells" and has 88 protons and 138 neutrons. it also has 88 electrons. the electrons are arranged like: 2 (1st shell) 8(2nd) 18(3rd) 32(4th) 18(5th) 8(6th) 2(7th)
Hydrogen atom has 1 proton and 1 electron; radium has 88 protons and electrons. Also radium is radioactive.
Radium is a chemical metal element. There are 88 electrons in a single atom.
The radium nitride (Ra3N2) has a black color.
The discoveries of radium and polonium doesn't affect the atom model.
its a redish silvery colour
There is no such atom as Radium 87 - it is Radium 88 and thus has 88. Francium is 87.
Radium has two valence electrons.
What Does Aluminum atom look like
The neutral radium atom has 88 electrons, the radium cation has 86 electrons.
In any neutral atom, the number of protons in it is equal to the number of electrons in it. A radium atom has 88 protons and electrons.
Radium has two valence electrons.
22088Ra, like all isotopes of radium, has 88 protons.
The isotope radium-232 has 144 neutrons.
what does the potassium atom loook like
The obtained isotope is radium-228.
Radium is modestly malleable if it is heated a bit. It will behave in a way similar to magnesium, which is a group 2 alkali earth metal like radium. But don't look for radium to be hammered or rolled into something. Radium is highly radioactive, and it isn't something that you want to be around, or to have around you. A link to the Wikipedia article on radium is provided. But there isn't a lot… Read More
you cant see an atom!
The number of electrons in a radium atom is usually 88. If it goes though bonding however, it will tend to lose those two outer electrons, and become a radium ion. If it bonds with oxygen, which has 6 outer electrons, it will lose the two outer electrons it has to become a radium ion with a full outer level of 86 electrons, and oxygen will get a complete outer level of 8 electrons. Radium… Read More
Since an alpha particle is a helium-4 nucleus, the resulting atom has an atomic mass that is 4 less, so 226 minus 4. Also, to get the element, look up the element number for radium, and subtract two from that.
The number of protons of an atom is given by its atomic number. Checking the periodic table, we see that the atom with 88 protons is radium. The isotope of radium with 138 neutrons would thus be 226Ra.
Radium glows in the dark and is in glow bands
It is an isotope of the element, radium (Ra), with 88 protons, 88 electrons and 147 neutrons (235 - 88 = 147).
look at the peridodic table.
i am asking to show me what an atom look like. the outside of it
radium has NO odor
Radium was discovered by the Curies in France in 1898, in samples of pitchblende which were found to be radioactive after removal of the uranium.
Radium decays in any of (at least) four different ways, depending on isotope and, in some cases, on luck, as some isotopes can decay in different ways. The most important way radium can decay is by alpha emission. Nearly all naturally occurring radium decays this way, and so do the majority of synthetic isotopes. In this case, radium emits an alpha particle, which can be regarded as a helium nucleus, and the daughter atom is… Read More
It looks like this:
Niels Bohr suggested a planetary model for the atom.
This atom hasn't an electrical charge.
You'd have to specify the isotope of thorium for us to definitively identify the isotope produced. A thorium atom that undergoes alpha decay will become a radium atom. However, we can't identify the specific isotope of radium without knowing the number of neutrons in the original thorium atom.
Because it, like all other alkaline earth metals (except for Beryllium), reacts violently (heat of reaction approx. 9.0 Kcal./g per atom) with water to form radium hydroxide and hydrogen gas. source heat of reaction: The Radiochemistry of Radium, National Academy of Sciences National Research Council
yes - but I don't know how I can show you
Radium - 228.
See the link below to see an image of the uranium atom.
An oxygen atom looks like a ball. There is a nucleus with protons in the center and electrons orbiting the nucleus.
It Is the Smallest paticles of matter
Radium-226 undergoes alpha decay to produce radon-222 plus one alpha particle and heat.
Radium. I think.
Radium element is in the s block. It has 88 protons in a single atom.
Radium, like all metals, is a cation.
Radium is dangerous to feel but i'm assuming it feels smooth like a pebble
An atom of sodium has 11 protons, 11 eletrons, and 11 nuetrons.
Radium helps the society and the world because it was used to look at x-rays.
Radium has an oxidation state of +2, Oxygen has an oxidation state of -2.....so it'll look like this Skeleton equation: Ra + O2 --> RaO.... Balanced equation 2Ra + O2---> 2RaO
