no some have 5 and 6 or more
There are a great number of things that can be found in the library that are important. Resources like encyclopedias are very important.
There are a number of things which motivate nations to expand their boundaries. Some of them are natural resources and establishing trade routes among other things.
There are a number of things that the World War 2 caused. This caused stagnation in production and industrial activities which hurt the economy, there were causalities and deaths among other things.
Quotas is the plural form of the word quota. A quota is fixed or limited number of things or people.
There are a number of things that Egypt traded with Mesopotamia. Some of the common ones include crops, animal, art, architecture and so much more.
then it would have 9 protons, 9 electrons,
There are 15 protons and 16 neutrons in the phosphorus atom. The atomic number, which is at the top of the square, represent the number of protons. In a neutral atom, there are the same amount of protons as well as electrons so there are 15 protons and 12 electrons. You can find the number of neutrons by subtracting the atomic number from the atomic mass and round to the nearest whole number. In this case, the atomic number would be 15 and the atomic mass is 31. 31 minus 15 is 16 neutrons total.
An atom is composed of electrons(-), protons(+), and neutrons( ). The nucleus is composed of neutrons and protons, and the electrons surround it.
Protons, neutrons (both in the nucleus) and electrons.
protons,neutrons and electrons
protons,neutrons and electrons
Protons aren't in electrons? The Protons and Neutrons are in the centre of the nucleus of an atom, whilst the electrons are outside the nucleus..
The mass number of an element is equal to the sum of the elements neutrons and protons.
The number of protons in the nucleus of an atom of this element will determine its atomic number. Only this. If the atom is not charged (in other words, not an ion), this is the same as the number of electrons in the atom. In that case, the number of electrons will be the same as the number of protons. But it is the proton count that sets or determines atomic number.
Ca-46 is an isotope of the calcium found on the periodic table. The atomic number is equivalent to how many protons the atom has and tells the identity of the element, if the number of protons is changed/ atomic mass number, the element would transmutate into another element. Thus, Ca always has 20 protons. Because it is not Ca++ or Ca- it is not changing the charge so no electrons are moving either. This means the number 46 is refering to a change in neutron in the nucleus of the atom, hence it is called an isotope. 46 is the number of protons plus neutrons so the isotope of Calcium has 20 protons, 20 electrons and 26 neutrons, or 46-20=26. Hope this clarifies things.
Electrons, Protons and Neutrons are Particles of atoms. They're 3 different things 2 of them (proton and neutron) exist inside the nucleus and electron revolves around it.
Its a normal atom if it have same protons, neutrons, and electrons to the one of the periodic table. If it have more or less neutrons than normal then its an isotope. If it have more protons than electrons then its a positive ion. If it have more electrons than protons then its a negative ion. An ion its a charged atom, more or less electrons than " normal " Isotopes its an atoms with the same number of protons, but different number of neutrons.
