In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge.  Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron. The correct option is option A.

<h3>What is atom?</h3>

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.

Quarks are present in protons and neutrons but not in electrons. Quarks are sub-atomic particles that have mass, but not an integer of charge.

Therefore, the correct option is option A.

A student measures the volume of a solution to be 0.01370 l. How many significant digits are in this measurement?
Mkey [24]

A student measures the volume of a solution to be 0.01370 have 5 significant digits in this measurement.

<h3>What are significant digits?</h3>

The significant digits are the minimum number from zero to nine for reporting any measurement where the digits are uncertain.

The significant digits starting from zero are not significant digits, decimal is not a significant digit, and ending zero after the decimal are significant digits.

Therefore, the student measures the volume of a solution to be 0.01370 5 significant digits are in this measurement.

Which direction does air circulate into low pressure zones in the northern and southern hemisphere
Yuri [45]
<span>Now consider a low pressure area on a disk as shown below.A parcel of air at point A would move toward the center of the low pressure area. That movement would take it farther away from the center of the disk and therefore it would move to the west. A parcel of air at B would move toward the center of the low pressure area which would also take it closer to the center of the spinning disk where its speed is greater than the surrounding points. It would appear to move to the east. With A moving to the west and B moving to the east the line from A to B is rotating counterclockwise.</span>

A chemical formula shows the kinds and numbers of _____ in the smallest representative unit of a substance.
Firdavs [7]

A chemical formula shows the kinds and numbers of <u>atoms</u> in the smallest representative unit of a substance.

<u>Explanation:</u>

In chemistry, a  formula unit is the empirical formula of "ionic or covalent network solid compound" that is used as an independent entity for "stoichiometric calculations". This formula is a representation of a molecule that uses chemical symbols.

The unit is the lowest whole number ratio of ions represented in an ionic compound. It gives the numbers of atoms representing the "smallest representative" unit of a substance. The number of atoms also tells us about the chemical and physical properties of the compound formed.
