Phosporus is a p block element too. AN ATOM HAS 15PROTONS AND NEUTRONS.
Isotopes are atoms (as regular as any!) which differ in number of neutrons in the nucleus. For example, hydrogen isotopes are:protium (nucleus contains 1 p),deuterium (1 p + 1 n), andtritium (1 p + 2 n).
The nucleus of an atom contains neutrons and protons. Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus. Because the nucleus is only made up of protons and neutrons, it is positively charged.
For finding the atomic mass of any element, we have to get sum of number of protons & number of neutrons. Atomic Mass (A) : p+n. * p = no. of protons. * n = no. of neutrons. Therefore, atomic mass of oxygen is 15.
Manganese is a metal element. Atomic mass number of it is 55.
P-31 has 16 neutrons and 15 protons
Oxygen is a p block element. It has 8 protons and neutrons.

Electrons are on the outside rings of an atom. neutrons and protons are together in the nucleus of the atom. There is always the same number of protons and electrons in an atom, equal to the atomic number of the element. The amount of neutrons varies, even between atoms of the same number, these varieties of an element are called isotopes. If the amount of protons and electrons varies, it is called an ion, and the chemical number is still equal to the amount of protons.
The nucleus of an atom contains neutrons and protons. Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus. Because the nucleus is only made up of protons and neutrons, it is positively charged.
how many neutrons there are in a phosphorus atom? The normal isotope of phosphorus is P - 31, which has 15 protons and 16 neutrons. Unstable isotopes are P-32 and P-33 which have 17 and 18 neutrons respectively.
For finding the atomic mass of any element, we have to get sum of number of protons & number of neutrons. Atomic Mass (A) : p+n. * p = no. of protons. * n = no. of neutrons. Therefore, atomic mass of oxygen is 15.
Manganese is a metal element. Atomic mass number of it is 55.
The mass number of an element is the total number of protons and neutrons in its nucleus. Gallium-72 has 31 protons (the atomic number of Gallium) and 41 neutrons, giving it a mass number of 72.
For the most part, yes the quantities of each are different. Light nucleii can have the same number of protons and neutrons and be stable enough to stay the same element (deuterium = 2H, 4He, 6Li , 10B, 12C, 14N, 16O, 20Ne, 24Mg, 28Si, 32S, 36Ar, 40Ca are stable), but a nucleus of a given element can sometimes have more or less neutrons, and be stable. Tin is the heaviest nucleus that has an isotope where #p = #n, and this isotope is very unstable
The three subatomic particles found in the nucleus of an atom are protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Together, they make up the structure of an atom.
