Thus, the fourth level can hold up to 32electrons: 2 in the s orbital, 6 in the three p orbitals, 10 in the five d orbitals, and 14 in the seven f orbitals. The sublevels of the first four principal energy levels and the maximum number of electrons that the sublevels can contain are summarized in Table 5.1.

hope this helps.

In which of the following is the number of electrons the ion contains given correctly

larisa [96]

Answer:

B. K+ has 18 electrons

Explanation:

Ions are formed when atoms of element gain or loose electrons.
When an atom looses electrons it forms a positively charged ion and when an atom gains electrons it forms a negatively charged ion.
Metal atoms such as potassium, magnesium and aluminium looses outer most electrons to positively charged ions.
Potassium atom has 19 electrons, 19 protons, with an electronic configuration of 2 : 8 : 8 : 1. To form an ion, K looses an electron to form a positively charged potassium ion (K+) with 18 electrons and 19 protons and an electronic configuration of 2:8:8.

The diagram below shows the different phase transitions that occur in matter.

Nimfa-mama [501]

The arrow that represents the transition in which dew is formed would be arrow 4.

<h3>How is dew formed?</h3>

Dew is formed by condensation. Condensation, in itself, involves a transition from a gas phase to a liquid phase.

From the diagram, the arrow that represents a transition from gas to liquid is arrow 4.

Thus, the arrow that represents the transition that leads to the formation of dew would be arrow 4.

A. False. If it is high tide in one place on Earth, the place exactly opposite to it will also have a high tide.

The gravitational attraction of the Moon and the inertia of the oceans cause two tidal bulges on opposite sides of the Earth.

B. True. Cassini used flybys of Venus, Earth and Jupiter as slingshots to reach Saturn.

C. True. The whole solar system moves around the galaxy.

D. True. If a planet’s gravity is not strong enough, the molecules in its atmosphere will have enough kinetic energy to escape into space.

E. False. The mass of an object is constant, but its weight changes according to the gravity of the planet.

F. False. To find the mass of an object, divide its weight by gravity.

$F = mg$ or weight = mass × gravity

∴ Mass = weight/gravity
