All elements in the periodic table are made of subatomic particles. These are protons, neutrons and electrons. The protons and neutrons are found in the centre of the atom, which makes up the atomic nucleus.Ans
Atoms contain even smaller particles within them called protons, neutrons, and electrons.Answer and Explanation: The positively charged particles that are found in the atomic nucleus are A) Protons. While it is also true that neutrons are ...
英文词汇:molecules,nucleus,protons,neutrons,electrons一定要加S么,为什么.还是一般情况?atom呢? 答案 就是单数复数啦...比如说proton就是一个质子,protons就是多个质子……氢就是one proton……在这几个词中,nucleus比较特殊.nucleus是单数,nuclei是复数【参见半径单数=radius复数=radii】相关推荐 1英文词汇:molecule...
1.The neutrons and protons form the core of the atom. 1.中质构成了原核。 2.Electrons are negatively charged with electricity,protons are positively charged. 2.电是带负电荷的,质是带正电荷的。 3.The nucleus of an atom consists of neutrons, protons and other particles. 3.原核由中、质其他粒...
From the given data, the corresponding elements and the number of each nucleons has to be found. Concept introduction: The smallest constituent of matter is atom. Each atom consist of subatomic particles called electrons, protons and neutrons. Protons and neutrons are pr...
Protons, neutrons, and electrons make up atoms. The protons and neutrons can be found in the nucleus and they account for the mass of the atom. The electrons, on the other hand, can be found around the nucleus.Answer and Explanation: ...
Atoms:Atoms consist of tiny particles called protons, neutrons and electrons. Proton and neutrons are present in the nucleus and the electron resides around the nucleus. The protons number will be same as the electrons count in the atom. ...
To solve the problem, we need to find the number of neutrons in hydrogen, helium, and lithium, and then sum them up. Let's break this down step by step.Step 1: Understand the Mass Number and Atomic Number The mass number (A) of
