How do you find out how many protons?

The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.

How many protons electrons and neutrons does an atom of Neodymium Nd have?

Diagram of the nuclear composition and electron configuration of an atom of neodymium-142 (atomic number: 60), the most common isotope of this element. The nucleus consists of 60 protons (red) and 82 neutrons (blue). 60 electrons (green) bind to the nucleus, successively occupying available electron shells (rings).

How much Neodymium is there in the world?

The reserves of neodymium are estimated at about eight million tonnes. Although it belongs to the rare-earth metals, neodymium is not rare at all. Its abundance in the Earth’s crust is about 38 mg/kg, which is the second highest among rare-earth elements, following cerium.

What is neodymium used for?

The most important use for neodymium is in an alloy with iron and boron to make very strong permanent magnets. This discovery, in 1983, made it possible to miniaturise many electronic devices, including mobile phones, microphones, loudspeakers and electronic musical instruments.

What element has 16 protons and 18 neutrons?

Name Sulfur

Are protons and electrons equal?

An atom contains equal numbers of protons and electrons . Since protons and electrons have equal and opposite charges , this means that atoms are neutral overall.

How many protons are in oxygen?


Is neodymium poisonous?

Ingested neodymium salts are regarded as only slightly toxic if they are soluble and non toxic if they are insoluble. Neodymium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure.

Is neodymium the strongest magnet?

Developed independently in 1984 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet available commercially.

Why are neodymium magnets so strong?

Neodymium magnets are so strong because of their high resistance to demagnetisation (coercivity) and their high levels of magnetic saturation allowing them to generate large magnetic fields.

Why are neodymium magnets illegal?

The Consumer Product Safety Commission has just banned the sale of Buckyballs, those magic magnets that can be shaped any which way, because the balls are a serious health hazard for children. It’s the first stop-sale order by the CPSC in 11 years.

Is neodymium expensive?

Neodymium magnets are relatively more expensive than ceramic magnets.

Is Lithium a rare earth?

Although lithium is widely distributed on Earth, it does not naturally occur in elemental form due to its high reactivity. … According to the Handbook of Lithium and Natural Calcium, “Lithium is a comparatively rare element, although it is found in many rocks and some brines, but always in very low concentrations.
