So it would be Sn with a mass number of 120. Antimony trioxide (Sb 3 O 2) Antimony pentafluoride (SbF 5) Antimony tribromide (SbBr 3) Interesting facts: Nicolas Lemery described it first in 1707. 0 0 0.

Get an answer for 'What element has 53 protons and 74 neutrons?' It rarely occurs free in nature. ... 51 protons and electrons and 72 neutrons.

PLAY. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. ... as there are a number of isotopes of this metalloid. Whichever you know, you subtract from the atomic mass. ... Daltons atomic theory stated that atoms of different elements combine in simple whole-number ratios to form compounds. A neutral atom has the same number of protons and electrons (charges cancel each other out). Gravity. chem.

Symbol Origin: From stibium, the ancient name for antimony sulfide Uses: hardens lead, plastics, chemicals Obtained From: stibnite, valentinite Related Links I currently do not know of any links for Antimony. This element corresponds to Kr-84. An isotope has an atomic number 51 and a mass number 123. A neutral atom has the same number of protons and electrons (charges cancel each other out). The periodic table lists every element on Earth and information about those elements. It is Sulpher . There are various "isotopes" of cesium, one of which has 82 neutrons , or 55+82=137 "nucleons". With 50 protons, its atomic number is 50, which is Sn. Write. It is often found in other ores such as silver, copper, and lead.

Protons have a positive charge distribution which decays approximately exponentially, with a mean square radius of about 0.8 fm. I'm really confused with this question, please help: An isotope of Element A contains the same number of neutrons … Protons and neutrons are both nucleons, which may be bound together by the nuclear force to form atomic nuclei. The atomic number is equal to the number of protons in an atom. Start studying Chemistry Test Chapter 4. and find homework help for other Science questions at eNotes How many protons and neutrons does cesium 137 have? Learn. Created by. ... Dalton thought that all atoms of a specific element have the same mass. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

The element that has 52 protons is tellurium, and the isotope of tellurium that has 76 neutrons is tellurium-128. Write the symbol for this ion (give the symbol for the nucleus and give the ionic charge as a right superscript). The mass number for an isotope is the sum of the number of protons (50) and neutrons (70). Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral. One isotope of a metallic element has mass number 74 and has 51 neutrons in the nucleus. An atom is electrically neutral, so if it has 50 electrons than it also has 50 protons. What element has 51 protons, 54 electrons, and 75 neutrons? Chemical Element.com - Antimony. Lutetium (Lu) has 104 neutrons To find this number for any element, take the atomic number (lutetium is 71 on the periodic table) and the mass number of the element and subtract to find neutrons.

True. at least for neutral elements, the number of electrons will always equal the number of protons, so also 6. as far as neutrons, you have to subtract the atomic number from the atomic mass (approx.

Cesium is number 55 in the periodic chart of the elements, which means that it has in its nucleus 55 protons . Test. The neutron is a subatomic particle, symbol n or n 0, with no net electric charge and a mass slightly greater than that of a proton.Protons and neutrons constitute the nuclei of atoms.Since protons and neutrons behave similarly within the nucleus, and each has a mass of approximately one atomic mass unit, they are both referred to as nucleons. The most common, stable form of iodine has an atomic number of 53 (protons) and an atomic weight of 127 (53 protons plus 74 neutrons). Learn vocabulary, terms, and more with flashcards, games, and other study tools. Atoms are made of protons, neutrons, and electrons. If an atom has 36 protons,48 neutrons,and 36 electrons then..What is the charge of the atom?..Makes a majority? From these data, you can easily calculate the mass number, that is 157 in this case. 22,10 Ne. The atomic weight is equal to the total number of particles in the atom's nucleus. This means the element is tin. Start studying Chemistry Test Chapter 4. Spell. The atomic number is the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table. Sulpher has many isotopes but Sulpher 32 is the most common. Its ores are widely distributed. ... neutral because the number of protons (positively charged) equals the number of electrons (negatively charged). The nucleus of the most common isotope of the hydrogen atom (with the chemical symbol "H") is a lone proton. An ion has an unequal number of protons … Match. ... part of an element that is the weighted average mass of the isotopes of that element.

... 51 protons, 51 electrons, 72 neutrons.

If you do, please let me know MLA Format for Citing This Page Bentor, Yinon. C. atomic number 6. that means 6 protons.
