The statement that is not true about subatomic particles is Proton and neutrons have the same charge.

The other statements are true about sub-atomic particles;

Protons and neutrons have almost the same mass. Protons and electrons have opposite charges. Unlike protons and electrons, neutrons have no charge. Further ExplanationAn atom An atom is defined as the smallest particle of an element that can take part in a chemical reaction.Atoms are made of energy shells and the inner nucleus.Subatomic particlesProtonsProtons are subatomic particles that are found in the nucleus of an atom. They are positively charged. with a charge of +1.The number of protons differ from one element to another and thus used as the atomic number of an individual element.The nucleus of an atom is positively charged due to the positive charge of the protons. Additionally, protons do not take part in chemical reactions but in nuclear reactions.Neutrons They are sub-atomic particles in an atom that are found in the nucleus of an atom. They have a zero charge or no charge.Neutrons are slightly heavier than protons.The number of protons and neutrons in a nucleus of an atom results to the atomic mass number of an atom. Like protons they only take part in nuclear reactions.Electrons They are found orbiting the nucleus on energy shells based on Clouds’ theory. Electrons are negatively charged each with a charge of -1.The number of electrons and protons in a neutral atom are equal. Additionally they have the least mass of the three sub-atomic particles.Electrons are the only sub-atomic particles that take part in chemical reactions.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
