The scientist uses an accelerator and high energy electrons to study the particles inside the protons of a helium atom, the particles under study are quarks.
Quarks are the elementary and fundamental part of matter. In Helium nucleus when the high energy is bombarded to study the particles inside the proton it is obvious that the scientist is studying the quarks inside the proton. In a proton there are two up quarks and one down quark present.
Answer:
Two non bonded electron pairs and four bonded electron pairs
Explanation:
An image of the compound as obtained from chemlibretext is attached to this answer.
The ion ICl4- ion, is an AX4E2 ion. This implies that there are four bond pairs and two lone pairs of electrons. As expected, the shape of the ion is square planar since the lone pairs are found above and below the plane of the square. This is clear from the image attached.
