What is the electronic configuration of the following atoms?
Nastasia [14]

Answer:The electron configuration of an atom shows the number of electrons in each sublevel in each energy level of the ground-state atom. To determine the electron configuration of a particular atom, start at the nucleus and add electrons one by one until the number of electrons equals the number of protons in the nucleus. Each added electron is assigned to the lowest-energy sublevel available. The first sublevel filled will be the 1s sublevel, then the 2s sublevel, the 2p sublevel, the 3s, 3p, 4s, 3d, and so on. This order is difficult to remember and often hard to determine from energy-level diagrams such as Figure 5.8

A more convenient way to remember the order is to use Figure 5.9. The principal energy levels are listed in columns, starting at the left with the 1s level. To use this figure, read along the diagonal lines in the direction of the arrow. The order is summarized under the diagram

Why is glass brittle
WITCHER [35]
Glass doesn't contain planes of atoms that can slip past each other, so there is no way to relieve stress. It has many microscopic cracks that act as seeds for fracture. It’s molecular structure is composed of tetrahedral crystals so it ruptured easily under stress

bija089 [108]

Answer: B or C

Explanation: The question does not include the variable or steps Brian is using so either one could be correct. It has to be the one that he is controlling though. This is because a control group is used to rule out any alternate explanations. Therefore the answer should be the one that he is trying to test out.

How many torr, atms, and psi is 303.9 kPa equal to?
klio [65]

Answer:

2.99 atm

2279.43 torr

44.07 psi

Explanation:

Torr, atms and psi all units are units of pressure.

Conversion from KPa to atm:

1 KPa is equal to 0.00987 atm. To convert from KPa to atm we will multiply the  given value with 0.00987 atm.

303.9 KPa × 0.00987 atm / 1 KPa

2.99 atm

Conversion from KPa to torr:

1 KPa is equal to the 7.5006 torr. To convert from KPa to torr we will multiply the KPa value by 7.5006.

303.9 KPa × 7.5006 torr/ 1 KPa

2279.43 torr

Conversion from KPa to psi:

psi is pound per square inch. 1 KPa is equal to the 0.1450 psi. To convert from KPa to psi we will multiply the KPa value by 0.1450 psi.

303.9 KPa × 0.1450 psi /  1 KPa

44.07 psi
