Answer:

Physical change

Explanation:

Physical change -

It is the type of reversible change , where there is change in the state of the matter , is referred to as a physical change .

There is no chemical process involved during state change , i.e. , no new substance is formed .

Hence , from the given statement of the question, the correct term is physical change.

<span>Isotopes are atoms of a particular element that contain a different number of neutrons.
An atom or element have same number of protons and electrons, but when there is a change in number of neutrons, this is called isotope of that element. There are many elements that have their isotopes like carbon have three isotopes Carbon 12, 13 and 14.</span>

The hydrogen atom is not actually electronegative enough to form bonds to xenon. were the xenon-hydrogen bond to exist, what wou

Marat540 [252]

Answer : The structure of $XeH_4$ will be square-planar.

Explanation :

In the given molecule $XeH_4$ , 'Xe' is the central atom and 'H' is the terminal atom.

Xenon has 8 valence electrons and hydrogen has 1 valence electron. Therefore, the total number of valence electrons are 8 + 4(1) = 12 electrons.

The number of electrons used in Xe-H bonding = 8 electrons

The remaining electrons which are used as lone pair on central atom (Xe) = 12 - 8 = 4 electrons

There are 4 bonding pairs and 2 lone pairs of electrons, they will be arranged in the octahedral arrangement around the central atom with 2 lone pairs of electrons on central atom. The lone pairs are arranged linearly across the central atom. The resulting structure will be square-planar.

The structure of $XeH_4$ is shown below.
