If an atom has 19 protons and 20 neutrons how much electrons does it have?

It depends. From the given information about the number of protons, we can be sure that we are talking about potassium. The number of neutrons in this case won't matter. If the question emphasizes "atom" then we can be sure that the particle is neutral. Then we know that for the particle to be neutral, it has to have the same number of electrons as protons. However, potassium will not stay neutral for long if given a chance. It will lose an electron when bonding with others, to eventually have 18.

Distinguish between atomic number and atomic mass?
The Atomic Number of an element is equal to the number of Protons/Electrons in the nucleus and the Atomic Weight is approximately the total number of Protons/Electrons and Neutrons combined. Using Carbon as an example: Total Protons/Electrons = 6, therefore the Atomic Number is 6 Total Neutrons = 6, and the Atomic Weight is 12 Question? The Atomic Number of Lithium = 3 The Atomic Weight of Lithium = 7 How many Protons/Electrons? How many Neutrons? Answer: Protons/Electrons = 3 Neutrons = 4
How do protons neutrons and electrons differ in terms of mass electrical charges and locations in the atom?
a neutron's location in an atom is in the core, or nucleus, of that atom, this nucleus is made of both neutrons and protons. the electrons of an atom are located in the electron cloud that surrounds the nucleus. to picture this, imagine a baseball field. the pitchers mat is the nucleus, and all the remaining area of the field, including the bleachers, is the electron cloud. everyone in that field, when spread out evenly among the field, are the electrons.
Why does the number of electrons have little effect on overall mass of atom?
The protons and neutrons that make up the nucleus are much heavier than an electron. Protons and neutrons are almost the same weight as each other and are just over 1800 times as heavy as an electron. there are the same number of electrons as protons in a neutral atom and typically a number of neutrons as well, so the percentage by weight of electrons is very small.
What are the nucleus of most atoms consist of?
The nucleus of an atom is made up of two types of subatomic particles, protons and neutrons which together are sometimes called nucleons. These subatomic particles are in turn made up of smaller particles called quarks.
What is in an atom the atomic part relatively mass?
In an atom, the atomic part that has a relatively large mass is the nucleus. The nucleus is located at the center of the atom and consists of positively charged protons and uncharged neutrons. The mass of the electrons, which orbit around the nucleus, is much smaller compared to that of the protons and neutrons.
How much neutrons and protons and electrons in a atom?
These numbers actually vary between atom to atom.
What two particles are in the nucleus?
(The constituent particles of an atom are the electron, the proton and the neutron; all three are fermions. However, the hydrogen-1 atom has no neutrons and the hydron ion has no electrons.) WIkipedia
Why are protons neutrons electrons called subatomic particles?
Because they are much smaller than an atom
Are electrons larger than neutrons and protons?
no. protons and neutrons are MUCH larger than electrons.
What is the same between neutrons and electrons?
When the number of electrons and neutrons are the same, it means that the number of protons will also be the same amount. For example a nitrogen atom has 7 electrons and 7 neutrons, this means that the number of protons will also be 7.
Is a calcium atom larger than a barrium atom?
Calcium contains 20 protons, 20 neutrons and 20 electrons (on average). Barium has 56 protons 81 neutrons and 56 electrons (again, on average). So, Barium is much larger.
Why the electron is most likely to be lost or gained by atom?
An atom is made up of 3 items: electrons which are negatively charged, protons which are positively charged, and neutrons which carry no charge. The protons and neutrons are closely grouped together in the nucleus of the atom. The electrons are in orbit around the nucleus in a similar manner as the planets orbit the sun. In this configuration it is much easier to lose or gain electrons than protons or neutrons.

The three particles that make up an atom are?
The electron, the proton and the neutron are the "building blocks" of the atom. Protons have a positive electrical charge (p+), and neutrons which have about the same mass, are electrically neutral, or have no electrical charged (n0). Electrons, which are much less massive than protons - only about 1/1836th as heavy - have a negative electrical charge (e-). All atoms are made of protons, neutrons and electrons, though most hydrogen (1H1) has just the proton in its nucleus and a lone electron in orbit.
How much protons neutrons and electrons does manganese have?
25 protons 25 electrons normally 30 neutrons but it can vary between 21 and 40.
