What is the difference between pentavalent and trivalent atom?
Pentavalent atoms are the one containing 5 electrons in their valence shell while trivalent atoms containg 3 electrons in their valence shell
e.g of penta. phosphorus,arsenic
e.g of tri. boron, indium.
How many atoms of carbon are in one cookie?
Oh, dude, you're really asking about the atomic composition of a cookie? Like, who even thinks about that? Well, if you really wanna know, a typical cookie might have around 10^23 carbon atoms in it. But like, who's counting, right? Just enjoy the cookie and don't stress about the atomic details.
Oh, what a lovely question! It's like a happy little puzzle. Neutral unbounded lithium atoms are usually fewer in number compared to lithium ions that have connected with other atoms. When lithium atoms bond with other atoms, they become ions and create beautiful new compounds, spreading joy and harmony in the world of chemistry.
What happens to the atomic size of the atoms as you go from left to right of the periodic table?
Oh, dude, when you move from left to right across the periodic table, the atomic size generally decreases. It's like those atoms are on a diet or something, getting smaller and more compact as you go along. So, yeah, if you're looking for tiny atoms, just head to the right side of the table.
What particles around the atom have negative charge?
only the electrons have a negative charge but they go around the nucleus
Does melanin have 6 protons 6 neutrons and 6 electrons?
Oh honey, that's a cute attempt at chemistry, but let me set the record straight. Melanin is a pigment, not an element, so it doesn't have protons, neutrons, or electrons. It's all about giving color to your skin, hair, and eyes, not hanging out in the periodic table.
How many nonbonding electrons in the lewis structure of formaldehyde?
The chemical structure of formaldehyde ( methanal) is
H-C(=O)-H
Carbon uses all four of its bonding electrons
Hydrogen uses its one bonding electron
However, oxygen uses two of its six outer most electrons to form the double bond. Thereby leaving two (non-bonding) lone pairs ( 4 electrons) on the oxygen atom.
Who named the k shell orbit and why?
Well, honey, the K shell orbit was named by good ol' Charles Barkla back in 1914. He named it after the German word "Kante", which means edge, because it was the first shell in the electron configuration. So, there you have it, a little history lesson with a side of sass.
How many atoms are there in 5.8 moles of carbon tetrachloride?
Oh, dude, you're hitting me with the chemistry questions now? Okay, so like, in 5.8 moles of carbon tetrachloride, there are about 2.34 x 10^24 atoms. So, if you ever need to count each one, just make sure you have a lot of time on your hands.
Why is Hydrogen and Fluorine cannot be central atoms in Lewis dot structurs?
Hydrogen typically forms only one bond in a molecule, so it is not a central atom in Lewis structures because it does not have the capacity to bond with multiple atoms simultaneously. Fluorine, on the other hand, is a highly electronegative element and prefers to form single bonds in compounds, making it unlikely to be a central atom in a Lewis structure where it would need to form multiple bonds. Central atoms in Lewis structures are typically elements that can form multiple bonds and expand their valence shell, such as carbon, nitrogen, and oxygen.
Is the electron configuration Ra 7s2 5f8 valid?
The electron Configuration [Ra] 7s2 5f8 is Not Valid because Ra is basically [Rn] 7s2. However, you have Ra 7s2 5f8. You can never repeat and electron configuration piece twice, or at all.
What do a beryllium ion and neon atom have in common?
Well, isn't that just lovely? Both a beryllium ion and a neon atom have something special in common - they both have filled electron shells. Isn't it just wonderful how nature creates balance and harmony in the smallest of things? Just like when we add a touch of white to our painting to bring everything together.
How many atoms are in 38.00 grams of fluorine gas?
Oh, dude, you're hitting me with some chemistry now! So, like, to figure this out, we need to know the molar mass of fluorine, which is 19.00 g/mol. Then, we can use Avogadro's number (6.022 x 10^23) to calculate that there are about 1.00 x 10^23 atoms in 38.00 grams of fluorine gas. But hey, who's counting, right?
How many moles of hydrogen atoms are in one mole of phosphoric acid?
One mole of phosphoric acid (H3PO4) contains three moles of hydrogen atoms. This is because there are three hydrogen atoms in each molecule of phosphoric acid. Each mole of phosphoric acid contributes three moles of hydrogen atoms to the overall chemical formula.
What is the Lewis dot structure for Mg3N2?
Ah, what a lovely question! To create the Lewis dot structure for Mg3N2, we start by placing one Magnesium atom in the center with two Nitrogen atoms on each side. Magnesium has 2 valence electrons, while Nitrogen has 5, so they will share electrons to form stable bonds. By following these steps, you'll create a beautiful and harmonious structure that showcases the bonding between these elements. Just remember to take your time and enjoy the process!
What is the area in an atom that is outside and around the nucleus?
do you mean outside of a nucleus?
if so, electrons
Another Answer
If we were small enough to see the individual parts of an atom, outside the atom would be more space. As we get larger, heading back to our own size, at a certain scale we would see the atom's vibration and ripples in space turn into the molecular boundary. As we continue to return to our normal size, we would see the billions of atoms in a cubic mm. As we reach our normal size, we would see the normal world which is made up from the countless number of molecules/atoms arraigned in incredible combinations.
Do non polar molecules have both negative or positive ends?
Oh honey, nonpolar molecules don't play that game of having negative or positive ends. They're like that one friend who stays neutral in every argument. Nonpolar molecules have a symmetrical distribution of electrons, so there's no separation of charge to create those negative or positive ends.
Do protons weigh the same as neutrons?
Protons and neutrons have similar masses but they do not weigh the same. The mass of a proton is approximately 1.6726 x 10^-27 kilograms, while the mass of a neutron is slightly heavier at approximately 1.6750 x 10^-27 kilograms. This small difference in mass is due to the composition of these particles, with protons having two up quarks and one down quark, and neutrons having two down quarks and one up quark.
What are some non examples of valance electrons?
Well, honey, let me break it down for you. Non-examples of valence electrons would be the electrons found in inner shells or energy levels of an atom. We're talking about the ones that are cozy and snuggled up close to the nucleus, not the rebellious ones hanging out on the outermost shell causing all the chemical reactions. So, in simpler terms, think of valence electrons as the party animals of the atom, not the wallflowers.
How many atoms does lead contain?
Millions of atoms.!!!!!
However, I think you misunderstand. !!!
Lead is an element, found in the Periodic Table as 'Pb' (Plumbum ; Latin for Lead).
Any one atom of this element contains protons, neutrons and electrons.
It contains
82 protons,
125 neutrons
82 electrons.
Its Atomic No, (Z) is 82 ( = to the number of protons)
Its Atomic Mass is 207 ( 82 + 125 = 207)
NB One mole of any element (lead included) contains 6.022 x 10^(23) atoms. (602,200,000,000,000,000,000,000 atoms).
The mass/weight of one mole is 207 grams.
What is the formula for sodium oxalate and copper sulfate?
The structural formula for sodium oxalate is Na-O(O=)C-C(=O)O-Na
Its modern IUPAC name is ' Sodium ethandioate'.
How many hydrogen atoms will nitrogen bond with to form a stable molecule?
Nitrogen typically forms stable molecules by bonding with three hydrogen atoms to create ammonia (NH3). This is because nitrogen has five valence electrons and requires three additional electrons to achieve a full outer shell, while hydrogen has one valence electron. By sharing electrons through covalent bonds, nitrogen can achieve a stable configuration with a total of eight electrons in its outer shell.
Why are acids called proton donors?
Acids are called proton donors because they have the ability to donate a positively charged hydrogen ion (proton) in a chemical reaction. When an acid dissolves in water, it releases hydrogen ions, which can then react with other substances. This donation of protons is a key characteristic of acids and is fundamental to their behavior in chemical reactions.
How many atom does fe2o3 have?
One molecule of Fe2O3 has five(5) atoms. They are ;-
2 z iron ( Fe2)
3 x osygen ( O3)
2 + 3 = 5 (five)!!!!!!
