The valence electrons are the electrons in the outermost electron shell of an atom.
Explanation:
The number of electrons in an atom's outermost valence shell governs its bondingbehaviour.
That is why elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table.
Generally, elements in Groups 1, 2, and 13 to 17 tend to react to form a closed shell, corresponding to the electron configuration <span><span>s2</span><span>p6</span></span>.
This tendency is called the octet rule, because the bonded atoms have eight valence electrons.
Answer:
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.
Weight can be explained as the force with which the gravity pulls an object. Your weight will not be the same in all planets. In moon, you will weigh far lesser than how much you weigh on the earth. However, in earth and in the moon, your mass will remain the same.
Answer:
At constant pressure
Explanation:
Enthalpy of a system may be defined as the system's internal energy in addition to the product of the volume and pressure of the system.
It can be regarded as the system's capacity of heat transfer and to do non- mechanical work.
The enthalpy of the system at constant pressure gives the amount of heat or energy that is either absorbed by the system or released by the system.
