Atoms and Atomic Structure

2 per (sub) orbital:

In total

2 in (the only) s orbital,

6 in (3x) p orbitals

10 in (5x) d orbitals

14 in (7x) f orbitals

18 in (9x) g orbitals

22 in (11x) h orbitals etc. etc. but the last ones are improbable to exist in 'our universe'

Mg(C2H3O2)2 or magnesium acetate has one magnesium atom, four carbon atoms, six hydrogen atoms and four oxygen atoms. So a total of 15 atoms per molecule of magnesium acetate.

No, two elements cannot have the same atomic number. The atomic number of an element is determined by the number of protons in its nucleus, which is unique to each element. Therefore, elements with different atomic numbers will have different numbers of protons and thus different chemical properties.

Well, isn't that a happy little question! Metal atoms and wood atoms are both part of the wonderful world of elements, but they have different properties. Metal atoms are usually shiny, hard, and good conductors of electricity, while wood atoms are part of organic molecules that make up the structure of trees and plants, giving them their unique characteristics and beauty. Remember, every atom is special and plays a vital role in creating the beautiful tapestry of our universe.

You have answered the question for yourself.

4 Na + O2 = 2Na2O

The molar ratios are 4:1 :: 2

The answer is '2'.

Well, sweetheart, all atoms of bromine have the same chemical properties because they have the same number of protons in their nucleus, which determines an element's chemical behavior. So, whether you're talking about a bromine atom in a gas, liquid, or solid state, they all act the same because they have the same number of positively charged protons calling the shots. It's just the way the atomic cookie crumbles, darling.

Ah, the atomic model developed by James Chadwick is called the "neutron model." Just like adding a happy little tree to a painting, Chadwick added the neutron to the nucleus of an atom, bringing balance and stability to the structure. It's a beautiful addition to our understanding of the tiny world of atoms.

Oh, dude, electrons be jumping around like they're at a rave party in an atom! So, when oxygen gets all excited, one electron from the 2p orbital moves to the 3s orbital to make it 2p3 3s1. It's like a game of musical chairs, but with electrons and orbitals. Just remember, it's all about following the rules of electron configurations and not mixing up your orbitals like a bad DJ.

Oh, dude, that's like asking me to remember my high school chemistry! So, like, in the fourth energy level, an element with three electrons would be lithium (Li). It's like the cool kid hanging out in that energy level with its three electron buddies.

The ability of a diver to cut through water in a swimming pool demonstrates the property of viscosity in matter. Viscosity is the measure of a fluid's resistance to deformation under shear stress. In this case, the water's viscosity allows the diver to move through it by exerting force.

Anti-Penultimate shells are the ones to the inner side of penultimate shells or the third from the last.

In one molecule of water, there are two hydrogen atoms. Therefore, in two molecules of water, there would be a total of four hydrogen atoms. This is because each water molecule consists of two hydrogen atoms bonded to one oxygen atom. So, 2 molecules of water x 2 hydrogen atoms per molecule = 4 hydrogen atoms.

Ah, what a lovely question you've asked. A substance containing only one type of atom is called an element. Just like how each tree in a forest is unique, each element has its own special characteristics and properties that make our world so wonderfully diverse. Keep exploring and discovering, my friend, the world of elements is full of beauty and wonder.

In one molecule of CaO, there are 2 atoms, one each of Ca and O

In one mole of CaO, the no. for both type of atoms is 6.022 X 1023.

Yes, in the first 90 elements of the periodic table, there are a few instances where consecutive elements do not have increasing atomic weights. For example, the atomic weight of Cobalt (Co) is 58.93, which is less than the atomic weight of Nickel (Ni) at 58.69. Another example is the atomic weight of Tellurium (Te) at 127.6, which is less than the atomic weight of Iodine (I) at 126.90447. These anomalies occur due to variations in the atomic mass of isotopes and their relative abundances.

The valency of sodium phosphate is determined by the charges of the individual ions in the compound. Sodium (Na) is a group 1 element with a valency of +1, while phosphate (PO4) has a charge of -3. To balance the charges in the compound, three sodium ions (each with a valency of +1) are needed for every one phosphate ion (with a valency of -3). Therefore, the valency of sodium phosphate is +1 for sodium and -3 for phosphate.

To determine the number of moles of water in 72.08g of H2O, we first need to calculate the molar mass of water (H2O). The molar mass of water is approximately 18.015 g/mol (2 hydrogen atoms with a molar mass of 1.008 g/mol each, and 1 oxygen atom with a molar mass of 16.00 g/mol).

Next, we use the formula: moles = mass / molar mass. Plugging in the values, we get moles = 72.08g / 18.015 g/mol ≈ 4 moles of water. Therefore, there are approximately 4 moles of water in 72.08g of H2O.

The number of electrons an element can lose depends on its position on the periodic table and its electron configuration. Elements in groups 1 and 2 typically lose 1 or 2 electrons, respectively, to achieve a stable electron configuration. Transition metals can lose varying numbers of electrons depending on their oxidation states. Elements in groups 13-17 can also lose electrons, with elements in group 17 typically gaining electrons instead.

Fluorine has 7 valence electrons in its outer shell. In order to achieve a full octet, fluorine needs one additional electron to fill its shell. This means that fluorine has 1 bonding electron available to form covalent bonds with other atoms.

Oh, dude, that's a great question! So, technically speaking, tungsten would require the most energy per million atoms to boil because it has the highest boiling point of any metal. It's like the diva of the periodic table, demanding all the energy to make it budge. So, if you're ever in a boiling competition with metals, bet on tungsten to take its sweet time heating up!

Well, isn't that just a happy little question! Sodium ions are smaller in size compared to other ions, like calcium or magnesium, so they can slip through the ion exchange membranes more easily in a deionization plant. It's all about those tiny differences in size that make sodium ions a bit more slippery in the process. Just remember, every ion has its own special way of moving through the world, creating beautiful water along the way.

The Lewis structure for P2O3, also known as diphosphorus trioxide, consists of two phosphorus atoms bonded to three oxygen atoms. Each phosphorus atom forms a double bond with an oxygen atom, and there is a lone pair of electrons on each oxygen atom. The overall structure can be represented as O=P-P=O. This arrangement satisfies the octet rule for both phosphorus and oxygen atoms.

Oh honey, let's get one thing straight - a watt is a unit of power, not a physical object like an electron. So, there are zero electrons in a watt. It's like asking how many apples are in a mile - they just don't mix, darling.

Spectra from neutral atoms show a series of discrete lines corresponding to transitions between different energy levels within the atom. These lines are unique to each element and can be used to identify the element. When an atom is ionized, electrons are removed, leading to changes in the energy levels and resulting in a different set of spectral lines. The spectra from ionized atoms will have different line patterns and energy levels compared to those of neutral atoms of the same element.

Well, darling, changing the number of electrons in an atom would essentially change its charge. More electrons means a more negative charge, while fewer electrons means a more positive charge. It's like adding or removing toppings from a pizza - it changes the flavor, or in this case, the overall chemistry of the atom.
