The 3-dimensional orientation of a sublevel is known as atomic orbital.
In quantum mechanics, Atomic orbitals are locations around an atom's nucleus where electrons are most likely to be at any particular time(specific orbits). These specific orbits exist in levels and can be broken down into sublevels.
Each sublevel has an orbital and it is oriented differently in 3-dimensional space.
The atomic orbital is a mathematical function that depicts how one or two electrons in an atom behave as seen in waves.

c) A substance has a high melting point and conducts electricity. What type of structure does it have
Answer:
Metallic structure
Explanation:
They have a high melting point due to the strong forces of attraction between the positive ions (cations) and the delocalised electrons. Moreover, they conduct electricity due to the sea of delocalised electrons.
[Extra: It could be an ionic compound since they also have a high melting point, however they only conduct electricity in liquid or aqeouus state.]

An isotope: is one of two or more forms of the same chemical element.
Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number.
A different number of neutrons giving each elemental isotope a different atomic weight.
Whats the different between chemical property and chemical change, and physical property and physical change?
Answer:
I think the answer is A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
Explanation:
I hope this helps.

distinguizh between the 4 states ofmatter
Answer:
There are four natural states of matter: Solids, liquids, gases and plasma. ... Solids have a definite shape, as well as mass and volume, and do not conform to the shape of the container in which they are placed. Solids also have a high density, meaning that the particles are tightly packed together.

Gasoline has a density of 0.7197 grams per milliliter. Calculate the mass, in grams, of a sample of gasoline with a volume of 48.5 milliliters.
Answer:
34.9103 or 34.9 g
Explanation:
Remember Density is a broken heart: m/v.
In this scenario (Let x = # of grams in the sample of gasoline),
D = 0.7198 g/mL = x g / 48.5 mL
So,
(0.7198 g/mL) * (48.5 mL) = x g
x g = 34.9103 = 34.9 g (Accounting for Significant Figures)

7. Describe the difference between a genetically modified organism (GMO) and an unmodified organism.
Answer:
there
Explanation:
organic food is farmed and manufactured per the guidelines put forth by the Department of Agriculture. Organic food is typically pesticide-free, GMO-free, and sustainably farmed.
Non-GMO food, or non-genetically modified food, has not been altered or engineered in any way. Non-GMO food doesn’t necessarily adhere to the same guidelines that organic food does.
GMO food has been genetically modified in some form, usually in a laboratory.

Here the nuclear decay of phosphorous to give S-32 is an example of beta-decay. Hence, the emitted particle is an electron. Thus, option b is correct.
What is beta decay ?The heavy unstable radioactive isotopes undergo nuclear decay by the emission of alpha or beta particle. Thus, there are mostly two types of decays, alpha decay and beta decay.
In alpha decay, the isotope emits a helium nuclei. Hence, mass number decreases by 4 units and atomic number decreases by 2 units. In beta decay, mass number does not change but atomic number increases by 1.
Here, P-32 undergo beta -decay by emitting an electron to form S -32. Hence, atomic number is increased by one. Therefore, the mission product is an electron option b.

Which type of mixture can be separated using a sieve?
A homogeneous mixture with components of varying sizes
A homogeneous mixture with components of the same size
A heterogeneous mixture with components of the same size
A heterogeneous mixture with components of varying sizes
Answer:
D: a heterogeneous mixture with components of varying sizes
Heterogeneous mixture is a combination of substances that doesn't have uniform composition and properties. Just by looking at the mixture you can differentiate the compounds because they are so different. Using a sieve, allows the components with different sizes to separate, while one is retained, the others can pass the holes in the sieve.

They can throw away less garbage.
They can throw away more garbage.
They can pollute the land.
None of the above.
none of the above is the answer i think?!
Answer:
none of the above
