Is Cs a stable element?

Only one isotope, 133Cs, is stable. The longest-lived radioisotopes are 135Cs with a half-life of 2.3 million years, 137Cs with a half-life of 30.1671 years and 134Cs with a half-life of 2.0652 years. All other isotopes have half-lives less than 2 weeks, most under an hour.

Is gold the softest metal?

Metals are typically solids. Solid metals can range from very hard and tough to bend, like Titanium, to very soft and easy to bend, like gold. Gold is one of the softest solid metals, which is why gold is often mixed with other metals when gold is used in jewelry.

Why is CS so reactive?

The higher the effective nuclear charge is, the greater the attraction is between electrons and the nucleus. Cesium’s low effective nuclear charge indicates that the nucleus does a poor job of attracting its electrons. Both of these factors make cesium extremely reactive.

What is Cs in element?

What type of metal is Cs?

alkali metal
cesium (Cs), also spelled caesium, chemical element of Group 1 (also called Group Ia) of the periodic table, the alkali metal group, and the first element to be discovered spectroscopically (1860), by German scientists Robert Bunsen and Gustav Kirchhoff, who named it for the unique blue lines of its spectrum (Latin …

Which gold is the softest?

24k gold
18k gold is about 75% pure gold, which makes it less durable than 14k gold because it contains more pure gold. The more pure gold present in a metal, the softer the metal will be. This is why 24k gold is the softest option and is prone to scratches and dents.

What are the names of the elements on the periodic table?

They are: hydrogen (H), oxygen (O), nitrogen (N) and carbon (C). The Periodic Table of Elements is arranged in rows called periods. Columns in the chart are grouped together by similar properties like gases, metals and earth. The number in each box is the number of atoms and the letters are the abbreviation for the symbol.
