Therefore, elements whose atoms can have the same number of valence electrons are grouped together in the periodic table of the elements. As a general rule, a main group element (except hydrogen or helium) tends to react to form a closed shell, corresponding to the electron configuration s2p6.

Answer:
Explanation:
The potential difference between one side of the wire causes the electric field inside the wire (causes the electrons to flow). However, inside the wire, it is still neutral. The electrons are just moving, the wire is not gaining or losing electrons.
Answer:
R = 400 ohms.
Explanation: Voltage of the battery, V = 40 V. Current in the unknown resistor I = 100mA. Let R is the resistance of the resistor. It can be calculated using Ohm's law it gives the relationship between the voltage, resistance and current.. R = V/I. R = 40 V/10-¹A. R = 400 Ohm's. So, the value of the resistance of the resistor is 400 Ohm's
power = (voltage) x (current)
17 w = (5 v) x (current)
current = (17 w) / (5 v) = 3.4 Amperes

1. velocidad media = desplazamiento/tiempo
desplazamiento = 0 porque el athelete vuelve al punto inicial en un círculo
velocidad media = desplazamiento/tiempo = 0/10 = 0
2. la distancia entre A y B es 5 cm porque
a^2 + b^2 = c^2 (el teorema de Pitágoras) así:
rapidez media = distancia/tiempo = 5/5 = 1 cm/s o 0.01 m/s
y yo no se cómo hacer 3-5 :( lo siento
3. Creo que es dos triángulo
s AB y CD menos la línea de fondo
5. Creo que es E + F porque B y D b y d cancelarse el uno al otro y C y C tambien pero no lo sé con seguridad.
