更新1: One last question... If the first element of group 1 pares to the last element of group 2... Which is more reactive? And which element of group 2 equals to the reactivity of any element in group 1? For example Ba = Na?? Just for an example..Your question is...
An element can, however, be decomposed into simpler substances, such as protons and neutrons or various combinations of them, by the methods of particle physics, e.g., by bombardment of the nucleus. The Atom The smallest unit of a chemical element that has the properties of that element is...
What is the atomic number of an element that has six protons and eight neutrons? Element X has three isotopes, ^{22}X, ^{23}X, and ^{25}X. The relative abundances are 60%, 35%, and 5% respectively. What is the average atomic mass foe element X?
Calcium is elementatomic number20 on theperiodic table, which means each atom of calcium has 20 protons. It has the periodic table symbol Ca and an atomic weight of 40.078. Calcium isn't found free in nature, but it can be purified into a soft silvery-whitealkaline earthmetal. Because the...
A chemical element is any substance that cannot be decomposed into simpler substances by ordinary chemical processes. Elements are the fundamental materials of which all matter is composed. Learn more about the origins, distribution, and characteristics
1.Land is a great stage for life, whilethenatural elements such as sun light, wind, earth, and water on that land arefundamental for life prospering.而土地是生命活动的舞台,土地上的自然元素——光、风、土、水等是繁育生命的基本条件。
Notice how early in the table it occurs; with just 22 protons, it's made of relatively small and light atoms. It's positioned right next to vanadium (V), so its atoms are of similar size, and that's why the two elements form many useful alloys. Key data Melting point: 1660°C (...
What is the name and symbol of the element that has an atomic number of 11 and 12 neutrons? How many electrons does a neutral atom of this element have? What element is this? Atomic Number = 6, Protons = 6, Electrons = 6, Atomic Weight = 12.0, Electrons in first energy level = 2...
