What makes an element more metallic than another?
Valentin [98]
Group names in the periodic table give clues about the metallic properties of the elements.
Metallic elements are found on the left side of the periodic table. A simple conception of metals describes them as a lattice of positive ions immersed in a sea of electrons.

Two sealed flasks each have a volume of 2.0 liters. Flask A contains N, O gas and Flask B contains H, gas both at 1
barxatty [35]

Answer:

Each gas have same number of molecules.

Explanation:

According to Avogadro law,

Equal volume of all the gases at same temperature and pressure have equal number of molecules.

Mathematical expression:

V ∝ n

V = Kn

V/n = K

k = constant

V = volume of gas

n = number of moles of gas

when volume change is changed from v1 to v2 and number of moles from n1 to n2 this law can be written as,

V1 / n1 = V2 /n2

This state that by increasing the number of moles of gas volume also goes to increase.

b. A beta particle contains neutrons. NO. It is a electron originated in the nucleus.

c. A beta particle is less massive than a gamma ray. NO. Gamma rays don't have mass while a beta particle has a mass which is half of one thousandth of the mass of a proton.

A. They are the most destructive earthquake waves.

D. They can move in a rolling pattern through rock, like an ocean  wave.

Explanation:

Surface waves are seismic waves that cause the most destruction during an earthquake.

Rayleigh waves are known to cause rolling pattern of rocks just like an ocean waves.

  • Seismic waves are elastic waves that notably transmits energy.
  • They usually accompany earthquakes.
  • There are two broad categories of these waves.
  • Surface and body waves.
  • Seismic surface waves are low frequency and long wavelength waves.
  • They travel very close to the surface.
  • They are made up of Love and Rayleigh waves.
  • Love waves travels laterally in a horizontal fashion.
  • Rayleigh waves rolls like ocean waves in the ground.
  • The bulk of the destruction caused during an earthquakes is due to these waves.
  • They are the last waves to arrive a seismic station
