how can you calculate the number of electrons present in a shell? pls help!!! will give brainliest
Answer:
The maximum number of electrons present in a particular shell is calculated by the formula 2n2, where “n” represents the shell number. For instance, K shell is the first shell and it can hold up to 2(1)2 = 2 electrons. Similarly, L shell is the second shell and it can hold up to 2(2).

Answer:
31: 1366.82
32: 6.45062
33: 12.50400
34: 210.42700
35: 63.88200 cm
36: -970.8772
Explanation:
4.550 x 300.4 = 1366.82
2.45002 + 4.0006 = 6.45062
26.004 - 13.5 = 12.50400
2.667 + (5.6 x 37.1) = 210.42700
2.34 x 4.55 x 6.0 = 63.88200
4.60 x 5.16 x 1.05 + 6.2 - 1002 = -970.8772
What does temperature indirectly measure? 1)Sound 2)Thermometers 3)Chemical Reactions 4)Heat
Answer:
Heat
Explanation:
Temperature is the average thermal energy (or heat) in a substance. Sound isn't really related, thermometers measure temperature, and chemical reactions can produce heat, but none of those are measured by temperature.

PLEASE HELP!!!
Most lakes have rivers flowing out of them, carrying water to the ocean. However, some
lakes, including Great Salt Lake and the Dead Sea, have no outlet. Water flowing into
these lakes leaves only through evaporation. Considering that the water flowing into the
lakes contains many dissolved substances, how does the lack of an outlet affect the
composition of these lakes? What would you expect to happen after many more years
of inflow and evaporation?
Answer:
I feel like it could lead to flooding
For the following element, predict the most likely oxidation number (charge) for its corresponding ion.
Aluminum
A. Al+3
B. Al+1
C. Al-3
D. Al-1
The most likely ion of Aluminum is Al³⁺ (group 3A) since losing three electrons is the most energetically favorable way for it to follow the octet rule.
Because the charge on ions is equivalent to their oxidation state, then +3 is the most likely oxidation number of Aluminum.
Write Cadmium nitride formula using criss cross method
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here calcium is having an oxidation state of +2 called as Ca^{2+}Ca2+ cation and NO_3^{-}NO3− is a polyatomic anion with oxidation state of -1.. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral Ca(NO_3)_2Ca(NO3)2

What do these two changes have in common?
boiling an egg
bleaching hair
Select all that apply.
Answer:
destruction of protein bonds
Explanation:
bleach dyes the hair by opening the hair cuticle and dissolving the color (melanin). The longer you leave it on, the more the protein bonds (keratin) are destroyed.
The heat denatures the protein in the egg by disrupting some of its weak bonds that held the molecule into shape
a) What is the role of neutrons in an atom?
b) How do we determine how many neutrons are in an atom?
Answer:
numer 1:Neutrons are required for the stability of nuclei, with the exception of the single-proton hydrogen nucleus. Neutrons are produced copiously in nuclear fission and fusion. They are a primary contributor to the nucleosynthesis of chemical elements within stars through fission, fusion, and neutron capture processes.
number 2:The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).let me know if i helped

what is the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom?
Answer:
9.13 x 10^-8 m
Explanation:
The maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.
What is wavelength?
Wavelength is defined as the distance between identical points in the adjacent cycle of a waveform signal propagated in space or along the wires.
Wavelength is calculated as wave speed and frequency.
Wavelength = speed/frequency
SI unit of wavelength is meter.
A ground state atom is an atom in which total energy of the electron can not be lowered by transferring one or more electrons to different orbitals.
Thus, the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.

Identify the cells in interphase, prophase, metaphase, anaphase, and telophase by circling the cells.
Answer: See diagram below
Explanation
Interphase- cell prepares to divide
Prophase- nucleolus disappears and chromosomes shorten
Metaphase- chromosome lines up in the center
Anapahase- chromatids are pulled apart to opposite poles
Telophase- cell about to/is divided into two
Nitrogen has 5 electrons in its valence shell. How many more electrons will it likely gain? As a result, what charge will the Nitrogen in the above problem have?
Answer: 3 electrons; charge = -3
Explanation:
Nitrogen will likely gain 3 electrons.
Nitrogen will therefore carry a charge of -3. (since gaining electrons causes a negative charge.
